You keep asking "What will I hit with this setup" on message boards

You don't cover your box with vinyl or carpet because you think
 it will affect SPL. 

You go to shows with those super ugly BARE MDF enclosures with
exposed wires and screws. BONUS! Add 5 Ghettopoints if you feel
offended with this statement. 

You go to Audio Shops (Circuit City, Best Buy, etc) and you act cocky because you think you know more than the sales guy

You hate MTX and RF just because they sell them at Circuit City

*NEW* You hate MB Quart because they are now owned by RF

*NEW* You bump the hell out on stop lights because you think you're
"The Shit" and you like attention 

You think your prefab bandpass box sounds good

You jump on brand bandwagons.  (I smell Vifa mids... )

You use lamp cords for power wires

You have different subs in the SAME box

You install neon lights on plain sight

You believe in the "Magic Three Upgrade" BS

You think your car runs better with a Grounding Kit

You drive a Civic (ok I'm just messin ;)
