Rockford Fostgate P310D4
Bought it off ebay, I now see why he sold it so cheap.
Hopefully this should fix it, if it comes loose again I will use epoxy next time. If it works with the glue, it was still a good deal. If not, I will be pissed.
The subwoofer was definately new. Hey may have tested it out and heard the flapping sound and decided to pawn it off on someone else. With luck I will find out tonight.
Appreciate the response.
