You're going to need to offer a little more info than that. Is this new and just installed? Or it was working fine then crapped out? Describe your setup and what troubleshooting you've done....

Have you checked that cables are tight and dials in sub are in correct positions? Also try swapping cable to it from another sub / output from receiver.

I'd try the cabling as tyhjaarpa suggested. Maybe try turning off the automatic on if you're using that. Otherwise probably just typical amp failure.

You can also try a low frequency sound check with a 3.5mm/rca connected to the sub.
