My ability to troubleshoot audio issues is pretty limited and Google is information overload, so hopefully the brain trust here can help me.

We have a 26' pontoon that we stripped down to the pontoons and restored a few years ago and installed a new MB Quart GMR-3 head unit, Pyle amp, speakers and speaker wire. The speakers and wires are in the same spot as they were prior to the restoration and I wired the new head unit in just like the old one. The radio sounds fine until I start the engine and am greeted with a popping / whine that gets louder with engine RPMs. This issue exists with FM radio and bluetooth.

In my limited knowledge of troubleshooting, I wired the radio and amp straight to a separate battery right under the console thinking I was getting interference from the engine - this helped, but the issue still exists. What else do I need to add, delete or modify to fix this?
