You basically run with audio to all speakers, front and rear. You can adjust them to front or rear, so, there in lies the problem. Whatever you see on the head unit, is sent to the rest of the coach. DVD, Navigation, etc. That is why i separated and installed seperate systems. I turned on the speakers to the tv, which comes set to off in the menu system of the TV from the factory. They dont design them to have the TV operational in motion.
The good thing is, you can customize it however you wish and there is space for the gear.
