Sorry to post such a basic question that Im sure gets asked a ton but what do you guys use between the sub and enclosure to make sure you getting a good seal? I looked into the foam strip for sealing doors but I couldnt find anything solid. I didnt know how well it would work. The stuff I looked at when sqeezed with very little presure colapses completely. Thanks again. BTW if there is a faq or guide that answers any of the easy questions like this please point me to it. I couldn't find a very good diy guide.
