So i just blew my rockford fosgate t1, i had my subwoofer in a sealed box in the trunk and i also at 1 point had my subwoofer in the decklid. i really miss the "no rattles" with having my sub free-aired in the decklid. My reason for removing the sub from the decklid was, once i put more power to it, i started to have very bad rattles that would litteraly scare the **** out of my passengers.

For those who dont remember






Anyways im upgrading to a 15" inch fosgate T2 and i want to put it in my decklid again. BUT this time i will build a box under, seal every little hole that air could leak thru and dynamat the whole decklid. i am not saying my system is loud enough to pop off windshields. But do you think there would be any possible threat to it with a 15inch woofer sitting so close?

Also if i seal it off what would u recommend using?
