I had a shop put in my stereo and they charged me for new wiring for everything. The head unit I am running is a pioneer 3100 dvd and I have the gains set fairly low. The stereo place set the gain higher the first week I got it but when I began messing with my amp I found it sounded better at higher volumes with a lower gain. I've kept it at that ever since, I don not turn my bass up very much either.

digital- I'm pretty sure they did all new wiring because theres wires for the amp, speakers, and some lead to my battery. I've got my amp on the carpet under my backseat, I've started to raise them any time i play it now.

Norm- All speakers sound fine can one of them still be damaged?

 

Yes.
