Hey all im new here ive read up a bunch and cant find some specifics. My issue is no bass at all in my sound system i have the 300 watt 9 or 10 speaker system (not sure) all door speakers and center dash speaker work the 2 bass speakers in the front and the 2 in the back are non op. Very crappy.i want to get it going by just replacing the amp. I just don't know which amp it is. Basically my question is which amp is responsible for the bass? Theres a few junkyards in my area and i can snag both for around 15 bucks each. (Hopefully they work) ive been very lucky with this car to my understanding its the rarest there is (for the usa) ita a 06 2.8T 6 speed manual. I got it for 1100 would't start turened out to be the ABS unit needed tires and a windsheild, a few other small things. And it had bad sun damaged paint that i fixed up ill post pics for yall shes pretty now. In the end its cost me around 1800 and id like to keep that cost low thats why im just lookong to replace the factory amp. Thanks for any input!
