Quick question. I installed an aftermarket sub and amp to my CTS BOSE system. Sounds great, love it. Problem though...when I turn off my radio my subs turn on and hum quite loud, and it doesnt stop until I turn the key off. I have the remote wire to the CCP fuse under the rear seat. Did I wire the remote to the hot side? Is this bad? Is it my ground? I tried moving the ground and it didn't help. I have the amp grounded to one of the 4 bolts that fasten the top of the rear seats to the trunk. Is this a bad ground? Can anyone help!!
