I put a Blu-ray player in the cabinet under my kitchen counter. I ran hdmi cables to my outside tv, rca and hdmi under the floor to the inside tv and oe Jensen stereo. So, I can watch bluray on either, or both at the same time. With the rca cable connected to the Jensen, the audio can play through the inside or outside speakers. I like to play concert videos sometimes when hanging around the campsite. I have a pioneer touch screen car stereo that I plan to replace the jensen unit with. There are several choices of speaker selector switches on amazon to control the 3 zones. I might get the rotary dial type and mount it in the cubby hole next to the radio.
