Hi Rich

The usual cause of this is that the fader has been turned to front speakers only. Give that a shot and I hope it helps you out.

Pull the unit out from the dash and check the wires first. Most aftermarket untils have a two pair of holes on either side, use nails to insert into the holes and press to release the unit after you get the fascia off. Check the wires carefully. Try taking one of the rear speakers out and plug the connectors from a door panel speaker on it to see if the speaker is good. If the speakers are bad, replace them. Crutchfield sells replacements you know will fit properly. Check the ground wires too!

Mode door may be dragging a bit. As long as everything works, I would not tear into it. Its a big job to repair.

My gas door will not open on my 2012 Nissan Maxima.
It looks to be pushed in too far

you could have wires coded with a red stripe this is usually pos . speakers will work with wires either way as they are only running the cone electromagnet .

Here are the stereo wiring colors.
