Kenwood head unit protect mode
I've got a 98 XJ. My brother outfitted it with a kenwood head unit, mtx terminator amp and sub, and some speakers. I put the head unit in wrong once and we think it might've bent it. It works on and off, going into protect mode after a few days of me resetting it. I recently discovered that the RCA cord going from the head unit to the amp had broken in the amp. I replaced it, hoping that was the cause of the protect problem. Played great last night and this morning but now went back into protect. What can I do? Do I need to get a new head unit?
