Title says it. I am confused by this. There is only one set of wires going to the satellites but I'm getting no sound from either side from the main speakers, while both tweeters and the sub are working fine. Is there a fuse inside the sattelites that I need to replace or something? Thanks for the help! PS. I am within warrenty but they are closed for the day and I want to figure this out ASAP. I miss my music! :-P
