I'm running a system right now with 8,000 watts (peak) going to 4 PA FUBAR 12's, all wired down to 1 ohm. Incredible amount of bass / vibration in the car (VW Beetle). I "sort of" mounted my amps onto the box, there's actually an amp rack (board) mounted to the front of the box, and the amps are put onto that. In a year I've had zero problems with the set-up and no amp damage of any kind. I wouldn't mount an amp *directly* onto the sub box, but you can be creative and get it "close". Check out the pics and you'll see what I mean:
