Okay so i just got this car in a trade from a friend. I know for a fact that the subs (Kicker Comp) and amp (Alpine) work great. Only problem is that when we traded he kept his headunit and I kept mine, which was bad. I took the wife's out of her car last night to put it in mine (going on a road trip today for vacation) and the cd player worked fine, but no sound. I can get pics of the wiring if you guys want, but I was just wondering what may be up. I think all the speakers run off the amp, so maybe the amp isn't getting any juice? I know this much about audio.......Nuff said!
