kind of a pain in the a$$. take the time and do it right, If need be rewire the speakers with more speaker wire its simple enough with wire crimpers and strippers plus a few butt connectors. Because i know the 7.1 setup for pc's come with special wiring unlike home stereos. 7.1 should be setup 1 center front, 1 front left, 1 front right, 1 rear right, 1 rear left, 1 center of left wall, and 1 center of right wall, which should be to either side of you.
