I have a ACA mono and a Icepower mono amp and would like to run thenACA amp only when I listen critically. I would like to do this for my front 2 or 3 channels i can turn on and off the amps remotely, but I am not sure how to wire it. I thoughtnabout using a xlr "Y" to go from my crossover to each of the 2 amps, but was told that will not work due to impedance. I was told that maybe I could install a 2nd pair of speaker wire jacks on the Icepower amp and plug the speaker wires from the ACA i to the icepower amp case and use a relay to select which speaker wires go tonthe speaker out jacks on the Icepower. Is there a simple circuit or a board Incould purchase that could do this with little impact on the sound?
