sub not working?
Vag com reveals a subwoofer fault stating open circuit.
Ive check all over for a sub fuse, left and right of the dash and in the trunk on the right side. haven't found anything. Does this car even have a sub amp or does it run of the radio like the rest of the speakers. I don't have B&O just the regular sound system that came with the 2011s
thanks
