Have the amp grounding redone properly. Ask them to scrape the grounding point down to bare shiny metal, and use copper washers when connecting ground. Quote:

The noise in call is unrelated. Probably there is no noise cancellation in the mic circuit. Check if your HU supports noise cancellation, and switch it on if it does.
RCA filters? What item is that? Unlikely to help in your case if it is a balun-choke type of filter.
If the RCA cables were to be bad, you would have had the other kinds of interference that you mention are not there in your system. Quote:

Overkill, and won't solve your problem. Signal processor is for a different functionality. |
