Ok thanks man and if another sub does that how can I fix it if it's back pressure?

the spider is very loose, and that one is new, the dmm reads a final impedence of 2 ohms, which is what we have it wired to.. the top left one http://s706.photobucket.com/user/dk_ah/media/VIDEO1006.mp4.html

I have 4 sa-12's in a wall and 1 of my speakers has more excursion than the others. anyone know what might cause this?
