this morning I was in my car and speakers were working as usual. I stopped to get gas. The car was turned off for about 3 minutes. When I got back into the car and started it a loud static and crackle coming from the driver side rear speaker. It happens on bands, AM FM and Sirius. It's never done this before and any information yall might have would be greatly appreciated. I will probably take it in Monday if I can.

 

it restored itself after being turned off for about 4 hours but information on this situation will help. Thanks
