Sound moves from speaker to speaker?

I have a 2009 DCSB with 180k miles and today, music started on all the speakers like normal, but then moved to the rear only, then moved to the front only, and then to the rear and stayed there.

I got home and waited an hour to go look at the issue. When I went to start up the truck, nothing happened. It didn't crank over, no lights on the dash, no radio, and no clicking noise.

I pop open the hood to make sure the terminals are connected to the battery posts and it was but decided to juggle it around. Went to start up the truck and it starts up! But oddly enough, my radio presets are gone, even though the terminals were never removed from the battery posts.

Any thoughts of what's happening? I did replace the head unit about 150k miles ago.

 

You have a loose connection somewhere if wiggling the cables caused a loss of resets. I would Check your ground points.

 

I'll check the ground points. Thanks!
