I have the PAC installed without the 12 volt and remote wire connected.

Whenever I press the brakes the speakers buzz, whenever I have the automatic lights on it buzzes. As soon as I stop braking or turn the automatic lights off it stops buzzing.


Any suggestions?

RCAs and amp power are on separate sides. Amp is grounded on the drivers side in the trunk on that ground stud.

Just tried a ground loop isolator and it did not do anything. I have a replacement aa gm44 coming in Incase mine is defective.
