Thank you for the reference. I will take a look at 12volt.

All I know about ported box construction (or what I thought I knew) is that they can be a heck of a lot pickier than a sealed box in terms of design and that they can either "make or break" the sub. I'm trying to "make" it if I can.

I know I can build it properly, just don't know anything about designing it or if the box that the manufacturer specified is good for sq or not.
