First night in our new 5th wheel and notice possible audio issues. As far as I can tell I have 2 speakers in the living area. 1 just above the TV in the ceiling and the other above the recliners facing the TV. There is one in the bedroom and 2 outdoor speakers. Zone A is the one above the TV, zone B is above recliners, and zone C is the bedroom. No sound outside as far as I can tell. I am thinking I need to pull the unit out and check the wiring. It is the Jensen JWM 70A.
