First, turn the volume down to zero. Do you still hear the whine with engine idling? If yes, get close to all 4 speakers and see if you hear the whine on all four or one or two speakers. If you hear the whine on one speaker, disassemble and scrape 6 pins on the amp where the harness plugs in. You might have poor connection.
Good luck!
