Op, just use one side. No biggie. Hook the center RCA to one channel, left or right on the power amp. Hook that same left or right speaker OUT to the speaker you want to power. Volume control? Where ever that CENTER speaker RCA is coming from, cable box, TV, something with a volume control..
You aren’t picky.. so have at it..
