18S Black SubWoofer just Stop working

I was doing a Sweet Sixteen event and it was performing great the whole night. Just as the event was over notice i din't hear or feel the bass. I notice the subwoofer wasn't playing. Luckily the event was over and my tops carried for the little time left. I am trying to find out what is wrong. Thought it might just be over heating we played from 7pm to 12am. Went i brought it home i tried everything but the sub refuse to play. I check my lines they worked fine with the tops I even tried using the bypass to the tops to ensure it wasnt the amp component that was defective. Tops played but nothing from the sub woofer. I think the woofer it self is blown. I would like to have it repaired or replaced. What steps do i have to take.
