Here is a rgeular prefab firebird box with fiberglassed top from fiberglasspros.com. It's my friends and fiberglasspros messed up when they put the top back on. their were lots of gaps where air passed through so now I got to tweak it a lil then put the top back on.
It's about 3 cubic feet tune at 50hz and gets real loud with his SA-12's. He did a 142 with those 2 subs in the regular sealed box so I imagine this box will get him to at least a 145 146
