Klipsch ProMedia 5.1 Sub -> Kenwood receiver?

[davismatson10]

So I have this receiver/amp, and I want to hook up the sub from this. Can someone help me out? I'm confused because the sub has it's own amp just built in, but I just want to have it run through my amp I'm already using. Also, I don't have the volume control thing from the 5.1 system, do I need that to get the sub to turn on?
