How to reset aftermarket adapter for 02 Impala.
So I unplugged my battery to install a new amp and when I plugged it back in, my kenwood aftermarket stereo won't turn on or anything. When I originally had the deck installed they had to also install a new wire harness and head unit adapter. Believe it or not this same thing has happened to me before except I had taken it into best buy and the tech basically said that the adapter needed to be reset. I watched the guy fix it in literally 30 seconds but I don't know the sequence of events to reset it. Anyone here have a clue? I've looked everywhere online!
