356qb Outdoor speakers not working
These speakers previously worked. They are zone c on my unit. Zones a & b work but not c, the outdoor speakers.
Brand new unit, haven't even camped in it yet. It has already been back to the dealer once.
I have pulled the head unit out of the cabinet and checked all speaker wires, all appear to be good connections. When zone c is selected, the outdoor speakers light up blue like the did before, but there is no sound. Fuse is good in the head unit too. Tried radio and DVD surround and they work on all zones except c, my outdoor speakers.
Any thing else I should check? Thoughts?
