[QUOTE="helotaxi, post: 2792588, member: 550915"] *cough*BULLSHIT*cough* There has to be a serious flow of alternating CURRENT to induce noise. The current in your remote wire is only a couple hundred milliamps at most and is not alternating. Actually in a lot of cases it is... Depending on the topology of the HU and amp, the outer part of the RCA is simply the other half of the signal, not a ground. The signal is ground isolated to keep from introducing noise into the signal from ground loops. By partially disconnecting the RCA all you did was cut the circuit so no signal is passing. If you are going to try to cut the shield, you need to ground it. It really sounds like you have a grounding issue with the HU. Either the signal is not ground isolated (which sucks as a design) or the HU is damaged resulting in the signal not being ground isolated (a common problem with Pioneer HUs, though I wouldn't rule that out just because you have a Sony).
