Question about Panasonic CQ-C1100U CD Player
If you unplug the RCA's (Jack wires) and the noise goes away - your problem is induced noise. Eminating from a Engine Computer, bad amplifier or radio grounding point or close proximity to power wires in the vehicle. The only fix is to re-route the RCA wire.
If the problem persists when disconnecting the RCA's the problem is the ground loop filter (or lack thereof) in the amplifier or a bad grounding point.
Make sure your grounding point for the amplifier is bare metal (sanded off paint) and on the vehicle chassis - not a interior support bracket.
Troubleshooting noise in an audio system can be tedious.
