Hi all. In a 2013 e350 sedan, is there a test that can be done to determine if the rear deck speakers are working. When I sit in the back seat and turn up the volume, no sound can be heard coming out. Any suggestions or how to isolate the sound to just those speakers. Any suggestions appreciated.

You can do the balance fade to either rear left or right only (assuming its same as my E250). This would allow you to isolated to those areas. I think there are like 2 speakers per door in rear but not sure, can only single out quadrants with the head unit.
