i removed my stock sub and put in a jl w6, with a ppi amp, 1000x4, bridged only to the sub =p kind of getto riged it, but sounds decent, also i need to get dynmat or something simliar, best place to get it?

Definately change em. Stockers suck.

boston acostoics

try indoaudio - got most my stuff there

the rears if they are like the b5's are powered by an external amp so if you wanna change the rear you are going to have to add an amp anyways.

altho if you want to do it right, put in a new amp and speakers....ikesound.com has really good prices and excellent customer service. also, crutchfield.com has good customer service and a huge selection...prices aren't anything special though

nothing that i'd put in my car. Good selection on headunits, thats about the only thing id buy from them but prices are eh.
