I just installed 2 amps. I used an audio control amp for the speakers with that GTO feature that turns on whenever it senses signal and I won’t need a remote wire. The problem is, it won’t turn off. I don’t know if there’s always an audio signal or something else. Anyways, I need to run a remote. What’s the easiest thing to tap into so I can get this damn thing off when the car turns off.
