So me and my buddy just installed an amp and subwoofer. Everything is wired correctly. Everything works until we turn off the jeep. Once we turn it off and pull the key out of the ignition it still runs until we open the driver side door. The engine light then turns on. We tried switching amps and moving the wires around but still the same result. Once we disconnect the power chord from the battery and start the engine the issue is gone. We don’t know what else to do and would appreciate any help or ideas.

 

This is the XJ section.
Maybe Mod can transfer this thread to the correct section.
