exactly what macbeth asked, what's rattling

RE: Sub rattles!! Why?
 

check all the screws on the box, and also if the foam surround on the sub isnt broken

could be:

blown speaker
vibrating against box
box vibrating against something in trunk
or car vibrating (but just sounds like it's the sub)

yeah it actually just went away by itself but it was the sub itself. i think it was vibrating against the box

That probably means you need to tighten it down a little more...
