If you are having DSP in your sound system (and also in that thread which you posted), it should help to reduce the noise.

I have routed the wires to each side of car (L to passenger side & R to driver side) and had the noise.
I reckon it was due to the fact that all the major wires passes on driver side of the car and R side was picking up the noise.

The noise in my car was associated to intereference from FRM (light) module / its wirings. As each time I read and code that module on my car, that noise increased.

With new harness, all issues resolved.
