My question is Why do my subs make a humming noise when I turn my car on but the volume is all the way down? And also Why do the subs turn on to full blast when I shut my head unit off? Any advice is appreciated.

If Anybody Can Help Or Know Someone Who Can Please Let Me Know Cause It Sort of Sucks Not Being Able To Shut Off The Cd Player.

I would recheck your ground of the amp and make sure you are using the proper awg wire.

The Ground Wire Has A Good Connection And Its 4 Awg Wire
