Stupidest Thing You Have Ever Heard When Talking With Someone About Car Audio?

I was just wondering what kind of stupid things people say when they talk about car audio. Here's mine:

This kid in my seminar said he was getting some Comp VR's so I asked if he was getting dual 2 or dual 4 and he goes "Oh it doesn't really matter, I don't use the voice coils anyways" I was like what?! and he went on to "fill me in" that voice coils only run highs and keep the sub from overheating. I told him that the voice coil runs the sub and he just goes OK whatever.

He also told me that Phoenix Gold wire is 24 Kt. Gold clear through, and that sealed box have higher SPL than ported boxes. He's the kind of kid you just want to slap him. It's funny to talk to him because he doesn't know jack and he really thinks he does.

Anyone else?

well, all my friends think that gains are the same as volume controls...


Posted by koolguy on 10-21-2001 03:40 PM:

my friend thinks that his thump subs are louder than my HE's just because they have tweets in the box.


Posted by Infinity526 on 10-21-2001 04:15 PM:

"My stock speakers sound awesome!"

yeah, whatever. . . .

155 Db can hurt your ears, HA can't we all hear fine???


Posted by The Trail Pimp on 10-21-2001 05:49 PM:

My friend says that, so he refuses to get new speakers or components he just keeps buying louder subs, and is convinced his deck gives 200w


Posted by Fozzie on 10-21-2001 05:49 PM:

man u guys dont even know stupid!!
this kid at my school, he goes 'yeah man i wanna get some sony exploids. (thats what he calls them). they sound tight without an amp.

lol the guy has like 4 pairs of REALLY beat up and OLD 6X9s all off of his deck and he wants to get 2 wal mart 12s cuz they're tight. he thinks that like ANY 12 is good no matter what it is.


Posted by tiggerjmp23 on 10-21-2001 05:57 PM:

I don't know who it was but I could have sworn I saw somebody on the forum claim they could hit 300db(it was a newbie I think). If you hit 300db, you would disintegrate! Literally!


Posted by SPL_Krayzie112 on 10-21-2001 06:11 PM:

oh this kid in Futureshop, he said: "people are saying the Xplods are POS" and his buddy said, "What are you talking about? They win the competitions, how can they be ****!"

After hearing this conversation I said out loud to my friend, "This Sony Xplods are just looks, I'll bet you I can find a POS looking sub that will beat that. And oh yeah they're pieces of ****. I install car audio why shouldnt I know." And the poser just fell quiet.


Posted by hobopenguin on 10-21-2001 06:17 PM:

"Wow, your car must be hittin atleast 100db!"

About two years ago I had just finished building a vented enclosure for a pair of PPI PC10's in the trunk of a Honda. The subs and the ports were facing toward the trunk. One of the other installers, who claims to have ten years plus experience, walks up and says
"Damn...... what kind of speakers are those?"

"They are PPI PC10's" I said.

"Hmmm... they look like bandpass" he says.

I'm like, "what the hell??? They look like bandpass? They, as in the subs, look like bandpass? What the hell are you talking about?"

"Yea, they look like bandpass speakers" he says

I remember his words verbatum because what he said was the butt of all jokes for at least a year. Everything after that "looked like bandpass"

"Why should I look on the Internet? Circuit city has the best stuff for cheap"

My store (tweeter) where I got all my first stuff installed, was telling me that my JBL 1200.1 can't possibly put out rated power because it's too small. They tried to convince me that their xtant1001x was SO much better because it put out an actual 1500 watts. I was like umm what's the difference between 1300 and 1500, besides I will strain my alternator before. They are like it'll be a lot louder, because your amp doesn't put out rated power. I told them about the magazine article, and they said that's with a high THD and stuff, when I told them it was at normal THD with all normal conditions, they told me that the magazine lied. So we went back to the xtant, and he honestly believed that 1500 watts would be noticeably louder than 1200+ from the JBL.

What a retard, then he tries to tell me that DEI components suck.

this kid at my work bet me fifty dollars that his two kick azz "Bumper" subs run by his "Rockford fosgate competition 100a2" amp which is hooked up to his stock hu through the high level inputs would destroy my 2 10" orion xtr's hooked to a pioneer deck and run by a (i know its crappy) bolt b400.4 amp. so we went outside and not having a meter, we had a guy from the service department judge. i beat him and i opened my trunk and what does he say but "wow, those subs have nice heat sinks" as i looked at him all confused he goes "holy shiit!! you got a bolt amp?? dont these cost like eight hundred dollars? I was gonna buy a stolen one once that put out 3000 watts but i decided not to give up my comp amp". At this i closed my trunk and took my money and walked away.


Posted by graham on 10-21-2001 08:00 PM:

some kid asked me "do u have a system yet" and i dint have one yet. He says "when you do get 2 12's and 100 watts, and make sure its "Boxed up". "boxed up you say? hmmm..... i give it a try" Lol

also this kid said "dude your subs are 2 close together, my brother said subs need to be 6 inches apart to play right.

i said, "Yeah but i have divider" lol dumbass


Posted by Speedy K on 10-21-2001 09:46 PM:

 

A salesman said to me that all subs sound the same.
they just go booom, and that's it.

I said ok goodbuy

You guys are always dogging on the people that work at Circuit City, but you don't realize the people that actually SHOP there on a daily basis. These are just some of the things I've heard.....

Can I get this installated today? or How much is it for an installment? How much for an installmentation?

It doesn't work when I "ground-out" the amp.

My speakers must be blown, cuz when I turn my radio up all the way they sound bad.

I just put in a bigger fuse on the amp, cuz they kept blowing.

Can't I just run the subs off the radio?

I'll give you $50 bucks for it. (are pricetags meaningless??)

I don't want RCAs.

Ground is ground. Just hook all the - speaker wires together. (heard this one from an "Electronics Engineer"!)

Where's your cheapest CD player? (immediately followed with...) Is this a pretty good one?

You mean it takes longer than 20 minutes to hook up an amp?




And this is my all-time favorite!! I still can't believe I heard this come out of a real live person's mouth.....

"The problem's gotta be the subs. Nothing can go wrong with the amp....it's just a big piece of metal."

On that note, I'd like to theorize that CC employees are not really ignorant, but just corrupted by the thoughtless ramblings of incoherent customers.

"Went to a comp today......i hit a 141.x but i would have been alot higher but i blew my tweeters on the way over here"


Posted by xDarythx on 10-21-2001 10:20 PM:

 

Hmm, lets see, I've had a few good ones...

A friend tried to tell me that a pair of "JL Comps" (I hope he doesn't mean components) could easily destroy a pair of MASSs, and that a sub would get loudest in a box where the sub was completely sealed inside the box because the bass would just "rattle around" in there and get really loud.

I had a tech at tweeter try to explain that a MASS had 20mm of two-way excursion, not one-way, and that my friend should get a pair of 10w3s over a mass because he would have to feed them less power.

I had another tech at this other place tell me that DEI Studio 6.5s were absolute ****.


Darthy, when i tell thiem about MASS, they task me how much is it in inches, because they aren't familiar with mms, then I tell them about how the inch number is just the P2P, and that the P2P of MASS is 11 1/4 inches, and the never believe me

this kid at school thinking that his 2 12" MTX thunder6000's run off a 200 watt sony expold amp with a crap HU and blown speakers will be better than my future system. 2 12" comp VR's with a kicker ZR360 amp (about 300 watts to each sub) and a poineer HU. And his system sounds like absoule crap!! i think he mush have his gains all the way up which he thinks is good and he is only giving each sub about 100 watts if that when they can handle around 250.

The shit that comes out of ignorant car audio customers, or "wannabe enthusiast"'s mounts has some degree of innocence to it though...
Ignorance, but really it's just what happens when you couple a cocky attitude with a topic that they don't even scratch the surface on...
That doesn't bug me so much, I expect that..


The greatest quantities of shit coming out of peoples mouths about car audio has to be attributed to salespeople!
And there's no innocence there, just a deception that should come back to haunt them come judgement day..
These are the guys that KNOW their stuff, or at least they are SUPPOSED to...

Short recent story:
A friend I work with came to me for advice, bought a new Maxima, wanted to add a real sub but leave the system stock.
I hooked him up with a PAC OEM-1, and had him remove his center-of-rear-deck-mounted factory 8" sub (which Nissan wants about $500 for a replacement, by the way!)..

Then I sent him to a local stereo shop that I have had experience with... (what, you think I have time to do a sub install for him?)
A local shop that has the best sales crew in my area (that says a lot about the quality of knowledge in my area... read on!)...
They first tried to sell him MTX's smallest Class D amp, told him it was about $500...
Then talked him into a Coustic 400se, which is 100x2 at 4 ohms, or 400 x 1 at 4 ohms.
Think they had a sales agenda?

They recommended a dual 4-ohm voice coil JL 12W3 to go with the amp!
There's no way to wire a dual 4-ohm sub to a 2 ohm stable amp and get full power out of it...
But he didn't know any better, so he had them install it...

About a month later, he told me his sub had stopped working, and that he had noticed his amp getting incredibly hot.

I suspect they wired the voice coils in parallel, and the little overacheiving amp smoked itself trying to operate at 2 ohms mono...

However...
Their verdict?
"Sub must be blown - removed sub to return to manufacturer for repair"

Can you believe that garbage?


Favorite pastime of mine:
On any day of the week, I can go into any stereo shop, play dumb, and let the shit talking begin. I'll let the salesperson talk themselves into a corner, I'll 'motivate' them into dropping at least 2 lies that form the foundation of their 'nieve customer' sales pitch..
Then I open up with both guns-o'-facts blazing and watch them melt like the wicked witch of the west...

Definitely, the greatest quantity of lies comes from your own stereo shops...
And those aren't innocent lies like the people who simply don't know better..

The ratings that people always believe whenever theres a huge sticker on top of the amp at walmartkmart or whererver else they decide to buy from when it says 1000watts x 4. (he's usign the front two channels for his stock speakers and the rear for his subs. I didnt even bother to ask what kind what box if any or how he plans on wiring it.

About 8 months ago, I remember a kid selling his subwoofers on ebay. In his auction, he stated that he hit "486 db's" with his subs, and that they have the potential to hit "800 db's" if powered right. Man, if people don't know what they are talking about, they should just shut up. That was HILARIOUS to read, though.


Posted by Nourdmrol3 on 10-22-2001 01:18 AM:

 

I was talkin to a kid at school about my new system a couple days ago and i told him i was lookin at 2 tempests and an mtx 81000d. I showed him all the stuff online and when i was showin him the 81000d he was like "you can't run two subs off a mono block amp, see it says 1000x1!" I was like WTF shut up and we argued for like 30 min. Then when we were lookin at the tempests he was like " dude 8 ohm subs really suck you should get 4 ohm like my Rockfords!" again i was like WTF dude im gonna wire them in parralel to get 4 ohm. why are people such dumbasses

I can't stand it when people argue with you about something they know nothing about. I've had people argue with me that pyramid is the ****, because it puts out 400 x 4, or whatever it claimed. When I tried to tell him it was crap, he wouldn't listen and bought it anyway. Man, did he pay the price for buying that amp when it blew 3 weeks later and put out dick for wattage. Hehe, serves him right...

800DB's......whoa
that's enough to shake a whole country


Posted by SystemAddict4 on 10-22-2001 01:31 AM:

 

Well, seeing as how 180 db's is the equivelent to an explosion, and 200 db's cannot be reached due to the laws of physics, I'd have to say that to reach 800 db's would be like the apocolypse. It would destroy the earth. Can you IMAGINE how much pressure that is??? Every persons head on this planet would explode.... That's what makes the comment so funny


Posted by streetrace_r on 10-22-2001 01:39 AM:

 

i thinkt hat 800db will absolutley disintegrate anything and everything in it;s path......lol


Posted by BrEaKaWaY on 10-22-2001 01:43 AM:

 

800 db's is to loud for you guys? Sorry let me turn down my HYPER PRO sub... you know how i do it... Pyramid only

see beaux did not even post to best one,

at that same comp he was telling me about a guy that got beat by a dual 8in Kiker setup,

He was running 15in Pyramids

My first though was way did he bring PYRAMID to a COMP. then beaux told me he was aurguing with the judges telling them the meter was wrong because he hit high 140's


LOL I would have like the seen the looks on the judges faces when he said that

That guy must have a horrible install, my one hyper pro hits 800db's

but thats cus i use 1/16" plywood with the holes ( you know the one ur garage has that u hang things on, looks like dots) well i use that so air can escape and increase spl as with sq but remeber not to tell anyone or think about this idea cus you might hit 800db's to

LOL, won't beat my Radio Shack 8" subs powered by a 10,000 watt Pyramid amp, or my friends 12" Thump subwoofers powered by a Kracko amplifier. I think we both must be hitting around 1000 db's.

walking into a car audio shop is about as frustrating as being a CPS major and walking into a CompUSA. I mean, some of these people know nothing! Sometimes I play dumb and to see the things these salespeople try to pull! It makes me feel really bad for people looking to get into car audio who know very little.

i dont really have too many really outrageous stories but here are a few:

1) went to a best buy and asked a salesperson about lightning audio's bolt (yellow) subs. Told the person i was looking for a serious system capable of being heard outside of my car (I figured that was a frequent question). He walked me over to the subs and said, "look, these are torture tested, which makes them some of the best subs in the market." I left.

2) I have this friend who is one of those people that knows a little about everything. He prides himself on his knowledge of car and home audio. He has amassed a nice home system and added a RF 60.2 and 12" sub to the trunck of his accord. So, when I told him about my 12" L7 and my orion XTR 900 he totally mocked me telling me that no one in their right mind would pour somewhere around 1000 watts into a single speaker. Now, this might be true for home audio where very refined enclosures and low amounts of exterior noise can be taken for granted however in a car its a different story. I told him he was right, and just chuckle every time he turns up his sub and I can't hear any difference from the stock system :-).


well, i guess thats all....

Ok so yesterday i go to get my exhaust fixed, and they turn on my car, i was in the other room and i could hear it a lil, just enough to know it was on, and the guy asked me what i got, I go ahhh just ****y legacy 10's, he said "they things sound real clear and pretty lound too" then he asked me why I have my amp up front, I told him thats for my highs, so he said so those are full range subs....
no thats to my front end speakers so then he ask if i got my subs runnin off my cd player, I said yep i got my CD player to put out over 200x2, he said thats how he had his. At this point I turned away and tried not to laugh (sp?)

Posted by RaVell_lott on 10-22-2001 04:51 AM:

 

dumbest thing i ever hear anyone say was when i walked into this car audio shop in a town 3 states from here and this salesman here comes up to me and i ask him what is the most powerful amp he has in the store and he takes me over to this really big pyramid amp and says now this baby will push almost 3000 watts but you have to have 3 car batteries and 4 caps within 3 inches of it so that it gets the power that it needs to push that much

that's not all 15 minutes later i am down the street at a fast food resarunt that they don't have here in utah and this guy comes in and i was like you on break he like no i don't work there i am like huh he says he just comes in to do the perfesional custom installs in cars for that shop so i says wow you must have a really cool setup in your car he says yeap so i ask him if i can c it and hear it he says yeah but it's not finished yet

so then we go out and he opens up his trunk and he has this really big pyramid amp and like 3 caps and a battery and 0 guage wire the subs were inverted so i couldn't c what kind they were but they have like 20 oz magnets so i'm like yeah lets here it

he must have been pushing like mid 110's cause he had the subs on hpf they weren't even moving

best part of the whole story is i ask him how much he spent and he says well cause i do install for em they give it to me at cost which i can't tell what it is but i payed 1600$ for the whole setup wait til i get my other 2 batteries then it will be so loud

i almost felt bad

I do about the same evil things that geolemon does, but with car dealers. It's also fun to just drive slowly thru and then STOP, back up...and stop again like you;re interested in a car...get the dealers to come after you...and let them sorta try to get near you, lol.


Worst thing I have ever heard:

There are way too many to name..
Just because I'm 16 the car audio shops try to sell me some stuff that is rather.. under par. It's usually at Best Buy when the salespeople can't tell me the difference between max power and RMS, and don't know what decibels are. I told him I was looking for a good sub that gets loud but still sounds decent, and he recommended some of the Bolt crap.. I asked him about the HE2 he had sitting there and he just shrugged it off like it wasn't any good.. then recommended me some Xplods

Stupid person : " You won't be able to sit there tomarrow"

Me: "Why not?"

Stupid: "I just put a pair of 12's in the trunk, and tomarrow I'm going to put a pair of 10's in the back seat"

Me: Why don't you just go with one set of 12's"

Stupid: The 12's are for the low bass and the 10's are for the punchy bass, that way I'll have the lowest punchiest car in town.

Me: ok, whay kind of subs are they

Stupid: The 12's are top of the line Rockwood, but I went a little cheaper on the 10's and went with Road Gear.

Me: HaHahahahahahhahahahahhahahahaahaha


I know its stupid but this guy was just so into it when he was telling me about it.


Posted by popimp on 10-22-2001 06:24 AM:

 

at least he understands the concepts he just doesn't know good brands. road gear is some sad stuff though..... i was suprised browsing through meijer they actually have stuff labeled as 1000 watt subwoofers.... wow

spacemonkey, are you an EE? As far as having smart people on the forum, I'll bet there are a decent amount of CS majors or EE's on here, as well as a lot of other college students/graduates. I'm a senior EE major myself.

The stupidest thing I've heard: I gave my cousin a listen to my system and he brought along a friend of his. My cousin was suitably impressed, and asked what I was running. I told him that I had 2 Diamond MacDaddy 12.8's off of a DEI 1100d, which meant next to nothing. Then the other kid said, "You should have gotten Polk Momos." I said, "Why would I want to waste my money like that?" I proceeded to ask him what type of subs he was running and he said "10" MTX's." I asked him which model, and he had no clue. He also had an MTX amp, and had no clue what model it was. What a dumba$$.

The air was being stimulated and pressurized by a giant Apollo rocket...

But is that really that different than stimulating and pressurizing the air with your big subwoofer cones?
Actually, in either case, you are pressurizing the air greater than "normal".

And when the Rocket's big subwoofer () left the area, it returned to normal atmospheric pressure... just like when your subwoofers are turned off... same deal (yeah right)

The rocket, after all, didn't have the advantage of "transfer function" that your small car interior does!

not Elect Eng .... chem eng. major, minor in physics(centered around subatomics..)


man tortoro... i cant seem to come up with a specific equasion that relates atmospheric pressure to sound intensity. throw me a bone here man

 


Posted by scooter1 on 10-22-2001 05:41 PM:

 

geolemon

Well, I don't think that the lauch should count because the rocket itself creates heat which alters the pressure of the gas around it thus allowing a louder sound to be recorded? Maybe I am off here? Where as with subs, the amount of heat created is fairly small and probably would not affect the gas in the cab enough to increase the dbs read on the meter. Anyone else think this?

Posted by The_spacemonkey on 10-22-2001 05:43 PM:

 

well increased heat would increase pressure to some degree which would allow for a higher db rating.

Actually, that penalizes the rocket..
Colder air is denser air, more pressure capability..

But with the rocket, since it is lifting off, that means that the air beneath the rocket is pressurized with more than the weight of the rocket itself, which must be an unbelievable weight...

Your subs couldn't come close to creating that pressure!

Nope. Ever notice that you system seems louder in the winter? Or your hearing seems more sensitive? Cold air = denser air. The pressure caused from heating the interior air in a car will escape somehow. You don't see anyone running their heaters at comps, do you?

 


Posted by The_spacemonkey on 10-22-2001 06:01 PM:

 

that is true as well...... well in this case you are right... but think of it this way. First.... with waves in a medium, the higher the pressure, the higher the intensity of the wave. we are agreed on that right?(think like this ... in a vacume, no pressure, there is no wave and with slight pressure there is extremely faint wave)
now think of a sealed enclosure full of air ... if you heat it the volume wants to increase for the same amount of room giving you more pressure.

P1V1\T1=p2v2\t2
v1=v2

Pressure1xtemperature2\temperature1=pressure2


but that is very true that density also plays a big role

well its very simple

hint

think of the equation for pressure in decibels

remeber there is a reference pressure and a <fill in blank> pressure

the end result fot 1 atm should be 194 dB

smaller speaker wire makes the subs more punchy or hit faster according to this kid in my class. Also a pair of LA storm 12's hit 142 off of an S2.250 while in the trunk of some old american V8. I say that is a in trunk measurement. He had it done by Ultimate Electronics.

More than twice as Powerful then the new BD1000 which is 1000 x 1 @2ohm, More Powerful than the BD1500 which is 1500x1@2ohm. this amp will put out 2600 watts @2ohm mono. very underated @ 500 x 2 @4ohms, this jumps to a underated 1000 x 2 @2ohms, and in 2ohm mono this amp can produce 2600 watts which is what the birthsheet says!

About 10 years ago some kid tried to sell me "Atomix" 12's for $30 each. He said that since you could see the logo on the speakers making straight lines backwards when they hit, rather than moving side to side at all, this meant they were very accurate and one of the top subs.

A friend of mine is going to install two 6x9 sin the rear deck. I told him how to do it, but then he said my friend at Circuit City told me to just use a pair of pilers to rip the bolts out from the bottom of the rear deck, then pull the speaker through the whole sideways!!! Then set the new ones back in there. Then he also advised that he bridge his amp to all four midrange drivers.

Sometimes I wonder, and this guys installs for a living at Circuit City!!

This 16 year old Pimple Factory told me that the MTX6500D was way better than the JL 500/1 because the 500/1 was high maintenance. I said "What do you mean High Maintenance?" He says " You have to adjust the settings for different types of music" as he points to the X-Over and the Gain. I laughed and said " thats a good one hah hah hah High Maintenance!". He looked at me funny and said "no I'm serious!" and I just laughed even harder as loud as I could while I made my way to the Checkout. Hah hah hah High Maintenance!

Posted by benasmith on 11-18-2001 06:11 PM:

 

Yesterday I was told that one of the reasons the MB Quart reference coaxials sound better than the component set from the same line is because the coaxials have a better basket. I was also told that MB Quart tweeters are better than JL tweeters because the MBQ tweets play up to 32,000hz while the JL tweets only play up to 20,000hz. I said "but you can't hear over 20,000hz, so it doesn't matter!" The salesman said that tweets that only play up to 20,000hz will distort as they reach their upper limit, while MBQ tweets will be easily within their range at 20,000hz. I like the salesman as a person, but I call B.S. to that!

but that's not as bad as the guy in the other shop who told me the JL XR components and coaxials will sound 10 times better in the car. uh......sure.

Just an hour ago, this sales MANAGER told me that JL Audio only gives 90 day warranties on their sub enclosure/woofer combinations but 1 year if you buy the woofer seperate and have the box custom built (actually the reverse is true, but 2 years for an enclosure).

His reason is what's funny: he said that JL figures most people who buy the enclosures will try to hook them up themselves and they won't do it right; but people who buy the woofers alone will have a custom box built by a professional who "knows what he's doing". (Because clearly any "professional" at Circuit City or Best Buy can build an enclosure just as good as JL Audio's and always hooks it up properly).

The funniest part is that he kept trying to justify this by saying, "I mean it just makes logical sense. JL Audio has to look out for themselves, right?"

I told him that, in fact, it makes no sense at all which is probably why JL Audio REALLY offers 2 year warranties on their enclosures but only 90 days on woofers (unless the box is certified, blah blah).

The look on his face was priceless.

Just to let you know, Best Buy doesnt even do custom install. Nevertheless, it's not difficult at all to build a box suited to a specific application which performs better in that instance than a mass produced box.

he also said that SVC subs suck because you cant get good power from your amps with them. and I'm too nice to beat someone down,so I'm just like "I dunno, it depends on the amp"

another guy told my friend to cut a big thing out of the bottom of his sealed box, and screw a peice of wood a little ways in there,a nd it would bump hard.A couple days latter,I relized he had seen a slot ported enclosure that was loud.

and these 2 guys were supposed to be the biggest audio buffs in town.No wonder I havent even visited my local car audio shop yet.

Went to a local audio shop and listened to a 15 solobaric. Asked him to play High Roller by Crystal Method (the bass hit is around 35 hertz) and it didn't play so i said you must have the box ported high. Then the guy looked at the top of the box and looked at me funny.

lmfao!!!!

i remember i was listening to a guy's system that consisted of 2 JL 15w3's and a PG MS2250 amp. it was a fairly large ported enclosure and it was LOUD. i asked him what his box was tuned to, and after hesitating, he said with a stupid look..."Well, its built to JL specs."

One of my friends keeps insisting that a sealed Isobrarik clamshell enclosure is the loudest type of enclosure.

He keeps saying, "Now if I were to switch boxes and put my two 12's in an Isobrarik box, it'll be twice as loud as my ported box because it's more efficient."

I got something stupid for ya... And this just happened.

I was talking with ABRA on AIM and he claimed that some sub had 2.5 coils... I was like, "dude? what are you smoking? yu cant have 2.5 coils... you either got 2 or 3... but nto half... i mean, you take one coil, chop it in half and do you end up with two HALVES? NO! You end up with 2 ENTIRE coils..." what a dope.



I can be so mean....

I was visiting Fry's Electronics one day and stopped by the car audio section. I was talking to the sales person there, who claimed he went to some Kicker school for 6 weeks to learn about their products. I was asking him about the Solobarics, and he tried to tell me that the L7 is the same thing as the L5, as in same woofer, except the L7 has a ported box, and the L5 is just the woofer. I was like wtf?

 

 

OMG, MY SIDES ARE HURTIN!!!!!!!!!!!!!!!!!!!!!!!!

when we told the salesman that we were looking for an amp for my son's 2 15" subs, he said we wouldn't be able to hear any bass in the car because you had to be farther away to hear such a long soundwave. This was at Best Buy.

my favorite are the people who come in ( i get one at least once a month) and have a cd player installed. Then when they come back to pick their car they get all mad because they thought they were still going to be able to use their stock radio as well

I can I can!!!!

RMS stands for Root mean square. Basically when you take a sinusodial wave you have a peak voltage. The time the waveform stays at the peak voltage is very very short, infact can the time actually be measured that the waveform is at peak voltage? Anyways, you shouldnt measure at that peak voltage because the actual output at that level is only at that peak for a very short time. If you look at a graph of a sine wave with time on the x axis and voltage on the y axis you see that the actual time spent at the maximum potential is only half of that when compared to a square wave. The square wave stays at the same max voltage as a sine wave, it just stays their a lot longer, this is why your amplifier can put out up to 2 times as much power when producing a square wave when compared to a sine wave. The amplifier is also more efficient when clipped. anyways the "meat" of the sinusodial wave is at the .707 point well approximatly .707 for a pure sine wave, so you multiply your voltage peak of the waveform by .707 and you get the RMS voltage! So your equivilant DC voltage would be .707 times the AC voltage's peak voltage. Same thing goes for current. You measure the RMS current the exact same way. So, when you multiply RMS voltage by RMS current you get very close to half the peak value!

Equations:

peakW = peakV * peakI

so assume we have an amplifier with a peak power rating of 100w, at 10v and 10a.

So:

peakW = 10v * 10a

100 = peakW

rmsW = peakV(.707) * peakI(.707)

So:

rmsW = 10(.707) * 10(.707)

rmsW = ~50

Oh and actually there is no such thing as RMS wattage...

Once I was at Ultimate Electronics trying to help my friend's brother pick out some equipment. The salesman told us that the Alpine speakers have better bass because of their huge surrounds! I told him larger surrounds don't make for more bass, it actually takes away cone area, cutting down on maximum displacement therefore less bass. He then told me that the alpines have a much larger diameter basket as compared to other 6.5" speakers therefore it isnt a big deal. I wish I had a tape measure on me at the time....

Please explain.

If you have a DVC 4 ohm and an amp that is 2 ohm stable and you can wire the DVC sub so the amp sees 2 ohms why won't the amp be able to give it the full power the manufacturer says?

If you bridge the amp it will see half the impedance, though, which would put it at 1 ohm.

I've been tryign to knock this concept into my sales councilor's heads forever, but they never seem to be able to get it straight


Posted by nasty_totoro on 09-05-2002 07:55 AM:

 

bridging an amp that "halve the impedance"

it DOUBLES the voltage accross the speaker terminals ...

its only that the current draw is the same as "halving the impedance" ...

impedance is wholy dependant on the load ... which hasnt changed ...

another car audio myth that went poofy courtesy of you fattah hungry totoro ...

sushi please

zzzzzzzzzzzzz


Posted by Jerry Parker on 09-05-2002 08:12 AM:

 

Hey totoro, what do you think about my post on RMS readings? Is it right?

Also, how come you were banned from Richard Clark's carsound messageboard?


Posted by automaticman on 09-05-2002 08:12 AM:

 

yeah but try explaining that to a sales councilor that can't even remember that 2 4 ohm subs go with a monoblock and 1 4ohm sub goes with a 2 channel...

*wipes tears from eyes*

Oh man, that was too much. I got SO many evil eyes from the people in this computer lab going throught reading that. Absolutely priceless.

I have a good laugh at all the incredibly stupid people that think they know something about car audio, but in reality they know nothing.

because this silly totoro pointed out that certain ID tech support comments about class D amps "killing" subs because they are class D are patently false ... not to mention the fact that they stated that JBL 1200.1 are the worse sub killers ...

money and advertising revenue talk more than yummy sushi

you can do a search for the actual post at carsound or elitecaraudio ....

there really is no such thing as "rms" power ... what people call "rms power" is really average power ... which is defined as 0.5 of peak on a sine wave ... its simpley the power derived from rms voltage and current ...


begs for sushi

zzzzzzzzzzz

That makes me mad that you were banned... I surely hope it was hephner who banned you and not RC, because RC seems to be a pretty nice guy.

Hehe, I know there is no such thing as RMS power, check the last line of my post!

Maybe you were eating too much sushi and missed that part?

But the rest is correct, right?

1/2" OSB Plywood and .6 cubic feet is perfectly fine for a subbox for a 12w3v2 with 600 watts.


oh, and my personal favorite is "you don't know what you're doing!" then i show them my install portfolio and the references and say, "heres the people call them, tehy all like my work." (damn jealous people, lol)


another good one was, JL is ****, sony kicks ***!


Posted by BASS on 09-06-2002 02:55 PM:

 

JL is ****! HAHA but thats just my opinion, I think one of my favorite stupid things was when some kid bet me whatever I wanted from mcdonalds that he was louder than me. I ask him what he has, "TWO ten inch pioneers, you only have ONE twelve inch" he also had a kenwood "600 watt" amp pushing them. Now I have a brahma 12" in a ported box with close to 1400 watts on it, in a little hatch back...needless to say, I chose mcdonalds for everyone

But Ive heard it all, circuit city/best buy has the best stuff, my stock system rocks, the usual...but it really sux when you cant convince your stubborn best friend that his 5 year old RF prefab box, and kenwood coax needs replaced...I even offered to pay for everything...still no

went to a car audio shop near me one time. In the store there was a photo book of cars I guess they done & photos from car shows. Me and some random guy were looking through the photos when the sales guuy came over and start talking to us.------ well he points to a group of photos... one photo is of a RED VW golf--- the other is a RED VW jetta. He tells me and this other guy that he put $35,000 into the golf to turn it into the jetta in the photo THEN------- spent $35,000 MORE! to change it back. .......... I walked out just as the other guy looking at the photos with me REALLY started believing the sales man.... down the road 10years later I go to a party where the guy (sales man) happens to live with 4 room mates in a small house. At the party to look cool for some girls he was talking **** to he pops in a video tape of a car show that he entered his newer VW bug...----- I don't know I guess his car is alright looking ----- basic stuff--- 4 subs & amp in a waterfall fiberglass box in the hatch back area.... --- well he starts getting all loud so people can hear him say ------ I put $70,000 in that car!
I don't ---- and didn't use sponsors. It all came right from here[holding his wallet in the air]
your fake if you use someone elses money to hook up your car!

guys first can tell you I could do the same thing to this car for $2,000 PLUS what assh*le would put $70,000 into his car and live with 4 people!


Man I just wanted him to look at me wrong ---- I can't stand people like him.


on another note----
is it me or does it make no sense to use AUDIO products for SPL comps ???
I mean these things don't play music and are built just to reach the highest SPL possible.
why even use subs & amps ?
it makes no sense cause they cost $$$$$$$$ and you just using them for the burst of power
I mean if people want to hear something loud why not just set off couple sticks of TNT for a crowd or better yet get one of those sh*Ty SPL car that look like they are held together with glue and stick 10 full sticks in it------ it be more fun
If it can't be an explosion use some air powered--- modulator.... I seen a show where a guy had one the put out 50,000 acoustical watts <-------- NOT electrical watts. then all you'd need is an air tank


basicly the TYPE of SPL the comps are is in no way related to audio


Posted by amcdude on 09-06-2002 04:52 PM:

 

Well, mine won't top all the hilarious posts so far, but I thought it was pretty funny. I was checking out an Elcipse HU (1997 model, beat up, it did work, barely, but the dude wanted $130 for it !!!!) Anyway, I was talking to him a little about car audio, mentioned that I had crap P-mid subs, and he says "Well, that's not too bad." Then I tell him I am planning on saving up and buying a DD sub, which drew a blank look. I said; "It stands for Digital Designs," to which he replied "Yeah, my friend is really into comps; he has one of those too; with the digital junk on one end." I guess he was thinking about some crap powered tube sub, and it was hard not to laugh. I didn't want to laugh, 'cause he didn't look like the real patient type, if you know what I mean.

Here's another: A friend of mine bought two "10 Pioneer subs at Wal-Mart for the low, low price of $35!! What a deal!! Actually, they sound almost as good as my $30 apiece P-mid "10, as long as they are in a undersized sealed enclosure; ported they sound like CRAP. Well, he talked to a guy who he though really know car audio recently. This dude told him that his Pioneer subs sucked, to which he agreed, but this "expert" was sold on Volfenhag subs!!!! Hahahahahahahaha, now I'm going to convince my buddy not to buy Volfenhag. He looked at a pair, and was impressed with the cast aluminum basket and "That thing weighed 14 pounds!!"

I love this thread, keep it coming!

resonance frequency is 35Db

Back in the day, when I was going to buy stuff from a local shop, the installer, who was going to recommend a box for me comes into my truck and knocks on the metal behind my seat and says,

“Yup, just as I thought your resonance frequency is 35Db.”

I’m like what the ****, where in the hell did you get that?

He says proudly, "I have a degree in acoustical engineering."


Ya sure…. Resonance frequency 35dB try more like 50hz.

He wasn’t close in anyway. He didn’t even get the units right. dB my ***
