I would like to be able to use two of my home theater speakers with the whole-house-audio system. Basically, they could serve double duty in this regard. In other words, if the theater system isn't being used, the speakers could play sound from the whole-house-audio system. Otherwise, I would need 'additional' speaker mounted in the room just for the whole-house-audio.
I am having difficulty coming up with a good way to do this, while keeping the signal sources isolated from each other. I don't want the signal from the theater amp, for example, feeding to the whole house amp via the speaker connection.
Any thoughts on this are appreciated.
