Ok, I decided to change both batterys out. Now my alpine unit stays on after i turn my truck off and open the door? It will remain on till i turn it off with the remote. All my lights and everything else works fine. Someone told me it could be a relay stuck after i reconnected the battery..i have no clue. It worked fine before i replaced the batterys. So i know its not the radio. Any help pr input would be Awesome!
