alright so i get home from work today turn my car off, radio stays on like it should until i open up the door, i go ahead n open the door to get out n POP! get a loud pop that seemed to of come from the rear deck speakers, i thought it might of been caused by my ipod so i switched the radio to am/fm and got the same result, the radio is the stock one that came in the car not the shaker 500. anyone have a similar issue or have an idea what could be causing this? oyea btw on the drive to work this morning it was fine everything was normal....thanks fellas
