Okay, I never realized how important my "big black box" (as my wife calls it) was until it seemed to just stop working. I know the sub is the most important part of a home theater, but wow...when you lose it, you really realize how important it is! Facts: Fuse is good, I checked it. It lights up no problems, like it's active volume control on it and all switches are the same as when it worked IT IS NOT PUTTING OUT ANY BASS What happened? Any ideas how I can test this out? Nothing on my receiver changed. It's the same on my xbox 360, PS3, and cable.
