    Without knowing more information, here's what you can do.
    • Run a new ground wire for the head unit to bare metal that connects to the body of the vehicle.
    • Clean the ground connections for the battery. There should be a ground wire going to the body and a ground wire going to the engine.
    • Make sure your amplifier grounds go to clean, bare metal.

    Get the idea? Alternator whine is often caused by a poor ground, possibly in multiple places.
