Aside from the rattle how does it sound? It might be the amp rattling on the sheet metal since it’s only held in with zip ties. If you have even a small piece of sound deadener you could put some in the back of the amp.Got it powered up last night. Not impressed. I have to CRANK the gains to get any meaningful excursion, and on top of that I have a bad rattle to track down. Also my cobbled together sub spacer has bowed and I will have to make a real spacer after all.
Did some post install research on setting the gains via measured voltage, which I'll look at tonight, but it may be that my 4 channel amp isn't suited to this use (go figure . . .). No real issue, amps are cheap now, I just don't want to have the car sitting for four days while I wait on shipping.
Also your amp might be 4 ohm in which case you are running parallel to a 4 ohm sub with 8 ohms.
