32-34hz you'll be fine with coppers on the 3500. Should sound great if you can really do 160 sq in of port (displaces 3.5 cubes at 34hz //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif).

Ive done the math, i can really do 160 in^2. It threw me off at first, i didnt realize how big the port volume would be, then i thought about it and was like, yeah...i can see that...Im just not sure how im going to design the box yet. I saw a box on SMD for 2 18s that the guy had a slot port with a divider down the middle the whole way, i may have to ask him about that.

Using three 6" tubes would save displacement. They would each need to be 15" deep and displace less than 1 cube. But you need to take into account more that just that. The tube needs to breath outside the box and inside, so you want it more that 6" from the interior box wall and more that 6" from the tailgate; not only that but you need room to play with the distance from the tailgate, as 6" may not be the optimal distance.
