Give them each atleast 30 square inches IMO...

As far as the tuning, what kind of music do you listen too? Do you want all out SPL or some SQ?

All out SPL? not with GTI's, those woofers sound **** good.

I'd go with 30+ per sub. As far as tuning goes, I prefer low tuning for daily, and you could tune higher if you plan on competing. What part of Louisville are you in? I may be able to help you out some if you need it.

going to be living on campus at u of l the 17th

i'll probably try and do a shared 80 sq in port if doable. and maybe make it removable.. tune to 28 for daily, 40 for other days.
