I have ordered the ever present PE 250w plate amp and the Tempest sub. They will show up within days. Next weekend I'll make my cabinet for the sealed sub. This is my first project. Here's my question: How do you seal the sub and amp into the cab? I've heard closed cell foam for the sub... but I'm interested in anyone that has pictures of the process and so on. The speaker doesn't need to be pretty because it's downfiring, but I'd like the amp to look decent. Anybody with any suggestions/tips, they would be greatly appreciated. Anybody with pictures is a saint. Thanks in advance!!
