Ok, so I took my Kenwood unit out of my truck. It was working perfectly fine with no problems. I put it in my wife's Hyundai b/c her radio was a pos. After I got everything working, when I tried the Ipod, only bass comes through. I used the usb cable, then a head phone jack and both times just bass. The cd player and radio were working properly though. This morning my wife takes her car, and says the cd player is now playing just bass, but the radio still works fine. Anybody got any ideas on how to fix the bass problem?
