I have a kenwood head unit from Double D mods, kenwood amp and JL sub. Out of nowhere, the rear speakers and sub stopped working. Also, the clock on the head unit reset back to 12a at the same time the speakers stopped working. I checked the fade, that wasn't it. Can anyone point me in the right direction of where to start checking? Door speakers work, so that rules out a blown fuse right? I was thinking maybe a loose wire on the adapter for the head unit?


***FIXED****

I dont know why the head unit reset, but it looks like thats what it did. Thanks to another forum, they suggested trying a CD, which the rear speakers worked. Turns out there is a setting in the Kenwood head unit for Bluetooth streaming and it was set to front speakers only.
