I was considering doing some light stereo work on my car. I really can't afford to change the head unit and even if I did, I would have to bypass the amps in the car. I don't want to do that. Upon some research I have found that the amps in the car equal 460w. Does anyone know if putting a bigger amp in place of the two rear ones and bridging it to a, lets say 10" sub possible? I'm trying to put a little more bass in my car with out having to sacrifice so much money on a hole know set up.
