Furrion is not known for making quality products. They are a regular topic of discussion on the Grand Design Owners' Forum (since GD uses them in their RVs). I - and a number of other Grand Design owners) have simply bypassed the Furrion unit altogether with a good quality sound bar, wireless subwoofer (installed behind the fireplace) and a compact, brand-name DVD/Blu-Ray player. The new system sounds infinitely better and is trouble-free.
