What do you think about 2 3" or 2 4" ports?

A friend wants me to build him a box for his new car its a scion t/c. anyway he has a dc level 4 15". we are planning a 3.25 cubed box after all displacements I have only done a few boxes with aero ports and they were in trunks. how would this sub and box do with a aero port in a hatch back car? we are planning on tuning it to 35 hertz with a 4" port. let me know what your thoughts are. We are not throwing out the idea of a slot port but trying to save some of the room. thanks in advance guys
