Answer
Unless your subwoofer is an active speaker (which I'm assuming it's not), you'll need an amplifier to drive the speaker.

The "subwoofer out" on this unit is a line level signal, and a passive speaker needs a speaker level signal. You can find active subwoofers at pretty reasonable prices online.
