I have one of those woofers and that box laying in my shed. I mounted 2 old school MTX thunder 5000 10's in that box , fed them 400 watts and blew the box apart at the seams. LOL. And the amp is crap too.
Before anybody asks why i have this crap let me just say , it was stored for someone. IT IS NOT MINE AND I DID NOT PAY FOR IT. LOL
