Does the whine change pitch with the engine, or is it constant?

Changes with the engine. Going to check the head unit ground, I had cut it from the harness when running a tablet so had to repair it, but I'd not be surprised if the joins not great.
Ground the rca cables. That used to be the go to repair for alt whine.
Good luck. I hate noise.

Same, even if I could not hear it with music playing, just knowing it's present would annoy me.
Got it sorted, not entirely sure how. Had to remove the DSP to check the input sensitivity switches, after putting it back in and moving the RCA just slightly, the noise is gone. Here's hoping it stays that way.
