I just installed one and it has high level inputs for off the speaker wires, connected them to the rear speaker wires and it rips!no noise or interference coming through it at all.

I'd go from the outputs of the 4 channel to the inputs of the mono.although, urinal biscuit is on the money, dont bother amping your rear speakers, just bridge the amp and run fronts only of it, will sound much better.
