I finally figured out my father's stereo enough to use it, along with the HDTV, for my Xbox 360. But when I watch movies I don't feel the Subwoofer working like it used to. Actually, I don't believe it's working at all. It's on, with a green light, and has all the volume knobs at something other than zero. It is connected to the stereo, and plugged in to an outlet. Why am I not feeling this?
