I have a 1992 Honda Accord Ex. I just installed the new Sony CDX-f7700. I had a sony receiver before and it gave no problems. I have a Kicker Class D Kx 600.1 Amplifier and 2-12 inch infinity subs with 300 watt RMS. The head unit comes on and plays fine. When the car is in parked the bass level is constant. However, when I drive off or when im driving somewhere the bass level just drops in half(it sounds like someone turned the bass down). The bass level returns and drops on its own. The amplifier is brand new and never cuts off. I have a Monster Cable Digital 1 farad Cap that always stays around 14 volts. I thinking it could be some wire that has a short circuit or something. Any suggestions?
