The box or the sealing off with the boot and lid to the bed? I have a bad of silicone on top of my box to the bed of the truck and it doesn't leak ever. It's been through some good soaks too

So it sounds great and loud as hell. No noticable freq dropoff. It wont play the high freq on Late Night Tip but most subs won't and it seems to be loud down to maybe 20 hz. All it all its an incredible improvement.
