i second that thats how i lost my first ampuse some rubber feet, or something in between to dampin the vibrations
you also have sony xplode 10 inch subs. so of course you wouldnt know if a box would vibrate or notI've heard the box is one of the best places to put it if you're worried about vibrations damaging your amp. Think about it, the box doesn't vibrate that much if it's built right. I don't know for sure though.
