What amp are you using to drive the speakers? Does it have control wiring ports available or are you just using the sub-room output on a receiver? You could just use an IR system from Xantech or Russound or one of the other many companies. Hardwire a IR Eye out on the deck, feed that to a Xantech box, and output IR through emitters to each device. I have a russound pre-amp that has pushbutton panels with IR for each room. The IR output from the preamp feeds IR to each device through emitters.
