I am moving into a new house, and the location I want to put my Home Theater does not have a basement under it, and the room is finished. Is there a website that might give me some tips on running speaker cable, and cable that might work well in this situation? Also, my receiver is 7.1. Is there a reasonably priced speaker cable that has 2 pairs per line? So I can run one single cable to the back and have the connections for both the rear and side surround speakers?
