Thanks for responding!
The PO (Prev. owner) CUT the factory connector OFF and used BUTT connectors to join Pioneer's wires to GM's. The radio is mounted with plastic brackets so the only thing left was the rear bracket/brace and it's screwed into plastic as well so I grounded the chassis of the radio. The Truck came with a premium sound system so the speakers don't have to use chassis ground to work. I think there is something going on with the power supplies to the radio, I think the radio might be connected to a circuit that isn't shielded.
Your thoughts would be appreciated!
