sealing question

[funeralxero]

i just recieved a box from my friend cuz we just built him a custom box for his kickers, anyway, he had his amp mounted to the top of the box, my amp isn't the same size as his so i have to seal the holes, any suggestions on how to get the strongest seal on these holes? like what to use to fill it in...thanks

just squirt some silicone into the holes and let dry

[funeralxero]

will that be strong enough and hold a good seal?

on my old box when i cahnged the amp I just put Rock Hard Puddy in the holes thne sand it down when it dries. Its perfect
