Port Question

The port area required depends on the power you are applying to the subs. Port noise becomes a factor with really high excursion. You do not want the port too small, trust me! But the larger port are you use, you need to make the port longer to keep the smae tuning frequency. If you were to just increase the port area and not the length, the tuning would go to a higher frequency, probably sounding really bad! So you need to use a box program to find out what will work for your application. You can make the port area bigger if you want, but you will also have to make it longer. Surprisingly, a small change in port area can result in a much longer port if you wish to keep a low tuning frequency. Maybe you already knew this...

build the box with the port on the same side of the subs like in jalat's picture, get the specs from him since he graciously offered (he knows about boxes from what I have seen). then you can screw around with placement up, back, forward...until you find what you like best. Jeeps are pretty square in the back so, a typical rectangular box will allow you to re-position as required.
