Huh. I never even noticed that the Crossfire had that feature.
So the amp just takes a control voltage from one or both sending-units? I've got it unplugged entirely right now and it didn't throw any error codes. Do you think it's OK to connect a new amplifier and just cap off those wires, if necessary?
