Also double check that amp gains aren't set too high.

I had the same problem. I tried everyhing and realized it was my NVX amp. If the amp body touched metal it would make a ton of noise. If I isolated it the noise would go away.

Update I found the buzz/ ground loop and it’s the fog lights. When I cut them off it goes away. But when I run a ground from the lights to the battery negative it still the same. So I’m guessing bad fog lights?
