JMAC, your the pimp daddy box master. I got to hand it to you, all the help you've been giving lately and not one or two different examples, you give the man 6 possible solutions. Good Job.
By the way, we just finished the ported enclosure you recommended for the Alum12Q's, and it sounds like it's gonna bang once we figure out why the subs aren't getting full power. But as little as the subs are moving, it's putting out a decent amount of bass.
