Question about Car Audio & Video
If this occurs with the head unit plugged directly into the amp (no signal processors inline, you probably have open shields on the head unit.
To check the shield ground, disconnect all RCA cables from the head unit and measure the resistance between the RCA shield on the head unit and the case of the head unit. It should read ~0 ohms.
