ive got a pretty heavy 5 channel mounted to the back, i just used the thickest screws i could find, they were #10's, maybe #12's, dont remember. i also put in these rubber washer things that were like 1/2" thick, when they screwed in they compressed to 1/4". to "abosorb" a little vibration, and space the amp away fromt he seat just a little for heat disipation. but mainly, i was worried the screws i was using were just a little too long
