I just got done watching Star Wars A New Hope and was thinking I was going to have some great surround sound. I heard almost nothing from my surround speakers. I am using a 20 or 22 gauge speaker wire for them. When I complete the install I will have a 12 gauge wire run to them. Is this my problem? I used the auto setup on the 2500 should I manually adjust that and crank up the db level for the surrounds? The surrounds are about 7 ft up on my wall and right between my couch.

Thanks for your help
