The opti's are pretty good subs and since you already have 2 12's I would snag 2 more and go with 4 12's. Subs up port back. Gonna need a good 4k+ and will need to upgrade your electrical to support this amount of power. As far as box tips I am no expert PM DonH, Pro-rabbit, they can answer all those questions for you.

Four 15's is pretty easy to do if you take out the 3rd row seating.
