Stereo noise issues

[h20boy22]

No eq in the system. Signal goes straight from head unit to amps.

Not to hijack, but since the topic was brought up. Regarding moving the B+ Yellow from the H/U to the same battery the amps pull power from - Does this have to all be the SAME battery in the stereo bank, or lets say if there are multiple batts in the stereo bank just make sure and go to the stereo bank vs. how it comes from the factory?

In my case, I need to make this last wire move pretty much just so everything is completely stereo bank dependent, and I have a battery in the stereo bank that takes about 1/4 of the work to get a wire to, except every other + and - related to the audio goes to the other batts on the stereo side.
