Pioneer 800 prs issues

[Dr. Slam 10+ year member]

This is my second 80prs and I having similar issues with both. I've tried everything from resetting it, rewiring it, separate grounds multiple times. I couldn't change the volume or get to the menu on the first and I can't get to the menu on this one either. It switches songs randomly and the rear channels having issues with distortion and cut in and out, on top of putting my sub amps into protect. I've swapped out 3 different pioneer head units ( same wiring harness and everything else ) but I'm only getting these issues with this one.

It acts normal randomly

What are my other options as far as troubleshooting it.
