Speakers Turn Off. No Sound From Left Side. 08 JBL

[RTAYLOR]

I need your help troubleshooting my sound problem with my 2008 4R with the JBL system. The problem is that the speakers on the left side of the vehicle will turn off while in operation. No sound will come from the front or rear driver's side speakers. When this happens, I can adjust the Balance on the stereo to the Left side and it will be completely quiet. The audio source doesn't matter. It has happened with the radio, CD, ipod, etc. It happens randomly so it is hard to replicate the issue. The only time that I have been able to notice the cause was after hitting a pot hole. But it doesn't do it after every bump or hole.

Have yall ever heard of this problem before? Do you have any suggestions?

Thanks in advance.

It would be easier to diagnose if it were just a single speaker, but the whole left side? hmmm. Take the door panels off yet and have a physical look?

Yes, it is the whole left side. I have not taken the door panels off for inspection.

I have this issue every now and then as well but only when I am using my USASPEC adapter for Sat radio (radio/CD are fine). In fact I think going over a bump is usually what causes it. The problem fixes itself when I turn off the car. Maybe pull the radio and check the connections in back, make sure no wires have pulled out of the connectors.
