My rear speakers are not working I got in the car this morning and there is just static coming out the back it increases if I turn up the volume and decrease when I turn it down. It was not like that yesterday. I put the speakers in last year and they have been working good since then until now. I did put in a new head unit about a month ago and everything was working fine and has been until yesterday. All my other speakers work and my head unit is working good.

 

Well for some reason they are working fine again and I didn't do anything except pull down the speaker bar a little so I could grab the wires and make sure they were in there

 

If you have the factory stereo with the joystick balance/fader control, it can cause issues with sound output. Try moving it.
