find that option and see if it controls the speakers as you need
When trailers used car stereos, that was the way it was done.
HOWEVER, Furrion makes RV-specific radios that have separate zones that can be individually turned off. There is no fader because there is two speakers per zone. I've got a different brand of radio in my trailer but it works the same way.
