My old DA5ES now belongs to a friend. He has a 5.1 set up in the main room and 2 speakers on his patio. Currently, to run the patio speakers, the center channel in the main room is sacrificed. I have an extra stereo amp that I would like to add to the system. I would much prefer to use that amp to power the front left and right in the main room, and use the DA5ES's amps to run the rest of the main room's speakers and the patio speakers. That way, he could get "separate's sound" when he listens to 2 channel stereo. He is also having a problem with the DA5ES's protection circuit when playing music at high volume, which I think can be remedied with the set up I'm proposing. I'm just looking for suggestions on how to do this...if it can be done. Thanks.
