An RCA cable, such as a stereo RCA, is comprised of a left and right channel. each plug is positive and negative. These carry an A/C audio signal, so that outer RCA negative, should not be a direct chassis or 12V DC ground. In most cases we come across, it is just that, DC on the signal negative, that is the source of the noise. 9 of 10 cases, its a result of the audio gear drawing from different battery sources.
