I found that if I turned off the "CLOCK" setting in setup screen on the radio, when powered off, the display would turn completely off. At least that's the way the JVC model radio I have works. (only cost me $100 from the store, so a pretty inexpensive unit.).

The system in the TH has a,b,c. switch bedroom only, coach only and both. I guess the dbl throw dbl pole is the ans to my question. Thanks. I have a new set of Sony marine speakers that came with the new stereo for the buggie. But I kept the MTX Audio marines in it so I can use the Sony's for the ext ones. Thanks everyone for the info.
And, great job on that instal. Looks good.
