Speakers should not be working when engine is not running and shifting the seat makes a difference means something is interfering with the electrical circuit. Could be a loose ground circuit or a short to power or a fault with control modules.

Detailed diagnostic is required to get to the bottom of this. Start by checking for trouble codes and this could be related to Body Control Modules.
