[QUOTE="ultimate157, post: 4304782, member: 566638"] If disconnected, and the noise goes away, then it means there is a problem from the RCA's back, aka RCA's, headunit, headunit wiring, battery. Most likely its the headunit; IIRC DC current cannot induce noise into an AC circuit, it has to be AC to AC. I've run my speaker wires touching my 1/0 power wire... Not an issue. Not sure about the RCA's because since its pre-amp and low voltage, its more susceptible to noise induction. Yup, that's my HU... Been running like that for 2 years now and couldn't be happier.
