Just have a quick question. I'm looking for the easiest & most inexpensive solution. I have KSW-12 powered subwoofer and anytime I try to connect it with the RCAs it makes this awful buzzing & thudding noise and nothing else. I'm frustrated b/c it worked awesome until I moved and now it doesn't do anything. This was an expensive piece and I just want it working again. Any help would be appreciated. Thanks
