What's the cubic size of your room? I hope you are not trying to fill a large space with that sub. That would contribute to over driving it.

Rattling or even "fluttering" sounds during heavy bass passages can be contributed to many things including the driver bottoming out, port noise (is this sub ported?), poor assembly like loose screws securing the driver and or amplifier (air escaping) or even user setup like having the receiver subwoofer pre-out set too high which in turn clips the signal.
