Aftermarket head unit issue

[jlgray81]

I installed an aftermarket unit about a month ago. Everything has been fine...until tonight. I started the truck up and noticed I was only getting sound from one speaker. Then I realized I lost all my settings on the unit. It was dim, the treble and bass wasn't the same, and my preset radio stations were back to the factory presets. Also seems that my antenna wasn't working because it wouldn't find any stations. What could be the issue? My main worry is that I'm only getting sound from rear passenger door speaker

Sounds like bad wiring or a faulty head unit.

All wiring is fine. Checked it out a little bit ago. I pulled out cd player fuse to check it. It was good. After I put it back in I checked the unit again. I had sound coming from 3 speakers. But not driver door speaker. Now I'm lost again

throw the factory unit in and see if all the speakers work. do you have an amp at all?
