Definitely get some of this to put inbetween the back of the woofer frame and the enclosure to insure you get a good seal with the subs.

On the Cheap side, and having some left. I would usually run a bead of caulk around them and smooth out, and lay the subs, and run another on the outside.(PITA) when you have swapp a bad sub out, but thanks to a razor knife..... Old school installation

Looking forward to that for sure man!!! Sweet. Nice work thus far. do you have help to get that enclosure and subs in? It may help. Its going be pretty heavy when subs go in. Take your time. Ive seen people rush and damage the enclosure as well as subs. Just take your time. You are almost back to some Bass man. You may have drop subs in after enclosure goes in. be sure center up on the outlets so no air leaks bye.

Yea man my dad is off today so when my car is ready at the mechanics gonna go get it and take it over to his place and hus gonna help load them I'm. I couldn't do it by myself
