I don't have RCA yet but when I removed the high level input, there is no sound and the buzz disappears.

As for the HU, there is no specific ground cable. I used the harness. I also tried connecting the GND cable from the harness to the HU chassis but this has no effect. This is all using high level input.

I am aware of the need of grounding the HU if case using the RCA's. Yes, the amp is quite cheap. it was only $60.

That black cable in the head units harness should ONLY be going to a metal chassis somewhere behind the head unit not to the rca's.

Swap to RCA's
