The error is usually in the ground path. First, of course, we have a signal source. If it is an indash radio, the case (outer metallic shell) of the radio is electrically connected to the chassis of the vehicle at it's point of mounting. If the radio is mounted in plastic , the radio's ground wire will make the connection to the chassis.

A few things could go wrong when using the chassis as a ground point for a high-power amplifier. First, the connection to the chassis needs to be secure and reliable. Second, your installer needs to brush or grind away any paint, rustproofing or undercoating from the metal before they drill a hole to make the connection.

It is Important to not have a chassis isolated – it must have some ground. Everything has a potential to everything else. Either control it or you have noise potential. Thus a chassis or cable shield must be connected to signal reference; however, no current flows in the connection between the shield and the signal reference.

For 95% of applications, grounding through the body is perfectly fine. For super-high current (SPL) applications, grounding through the frame may be more effective. In rare cases however, such as what bikinpunk describes, running a dedicated wire to complete the circuit just works and/or makes the most sense. Bottom line: Don't over-think it.
