More info is of course needed but some of the reasons that I've found for EP500 rattles are:
1) Some sort of damage
2) Wire rubbing on the amp casing
3) Wire rubbing on the port casing
4) Speaker wire terminals loose (there is a second set inside the sub on the amp casing)
5) Vibrations of something near the sub (sub cable touching, surge protector, etc.)
7) Spikes vibrating on uneven surface (need to make sure they are properly seated or switch to rubber pads)
Hope this helps.
