I have a Rockford Fosgate P1 sub (newer 1/silver) on almost any song all it does is rattle i took it in and got it replaced but it still just ridiculously horrible, the only time it won't rattle is if nothing on the amp is turned up at all. My other sub is a sony 1200 W explode would this also be causing the problem for the 300 w rockford, **note it is in an enclosed box which does rattle some but i took it out and it still rattled like crazy**

any suggestions would be great thanks!!
