Thanks for all the replies!  It doesn’t seem to hurt anything so at this point, I’m just going to leave it in place. I’m actually moving the receiver and the TV down to a console fireplace and “televator” where the passenger side couch was located, so I do not need any switching of any kind. The TV will have its own sound bar and the new NAV flatscreen stereo I installed will utilize the old ADS speakers (except the middle).  I really should’ve put some of these upgrades on hold until I could figure out some of the basic air system problems, but I can’t help it!
