Here's what I'm going to have: JBL NSP-1 Kenwood VR-507 Sony SA-WM40 Panasonic RV-31K What I need to figure out is what cables I'll need. Correct me if I'm wrong, but I'll need a mono RCA for the sub, another mono RCA from the DVD player to my TV (composite), and a set of RCAs for the audio from my DVD player to the receiver. Unless there's another way I'm supposed to wire this up? I see there is a subwoofer connection and a pre-amp subwoofer connection on the VR-507. Does the subwoofer connection from my DVD player to to the pre-amp, then the subwoofer connection go to the sub? How high should my surround speakers be mounted? I'm not sure where I'm supposed to put these.
