Yes. This didn't change the noise at all. I disconnected the RCA's at each of the amps, all of the amps, and at the back of the stereo (Aux) as well. No change. The one thing I didn't do is disconnect the speaker wires. The article above says long speaker wires can cause a problem, but there's nothing I can do about that except to wrap them in a ferrite dealy close to the amp.
It's good that you've narrowed it down this far though! Are the speaker wires the originals or were new ones run when the system was upgraded? If original did you have any noise prior to this? It's possible you have a wire which has had the insulation worn away and is touching ground. If new - what type of wire did you use?
