Check the speaker set up menu in the Pioneer, Make sure that the sub out is turned on. You may also need to set the other speakers to small.
If that doesn't help then the cable connecting the sub to the receiver may be bad. Is the sub plugged into a working AC outlet? Is the a light indicating that the sub is on?
