hooking up passive sub to Sony receiver.help!! (1 Viewer)

[KEVINTHONGS]

I just got this huge passive subwoofer that just has the red and black wires sticking out of it. I currently have an older sony strd511 receiver that doesn't have any sub connections on the back.

How do I connect this sub to my receiver? Or can I even use this sub at all? Any help please!! Thanks

I think you might need to buy a separate subwoofer amplifier.
