Amp rattle?

Yo guys, whenever i play my music kind of low, like 15/35 on the HU, i hear a rattle coming from my amp with every bass note that hits, it only happens on deep bass notes and i know the rattle is coming from somewhere in the amp, just wondering woulod you guys maybe have some kind of idea whats doin this? its a hifonics bx1500d mounted on the back of a box with 2 12"L7's, i know its not from the subs bumpin, because the bos hardly shakes and i tried tkaing the amp off the box but it still has the same problem.

When i had my amp attached to the back of my box it would rattle like crazy when i turned up the volume. so i made an amp rack and boom no more rattle.

or you can try and put like a cloth, or some dampening material behind the amp.
