Have you tried another set of speakers in your system? even a pair of headphones (directly connected to your soundcard, not the headphone port you can have on your speaker control)? If you get good sound through headphones/other speakers- it's likely a fuse in the subwoofer or the speaker set itself has gone bad. Usually the subwoofer has the power unit for the speaker set- check and see if the fuse has blown. If so, you can get a replacement either from a place like Home Depot, Radioshack, your local hardware store, even Autozone or Advanced Auto (even Wal-Mart usually has a few fuses). Check the documentation for your speakers to make certain you get the correct amperage fuse- too low, it will blow the fuse again; too high: it blows the speakers.
