What subs would sound best in this fox box?

DODGE QUAD & CREW CAB 2-12" VENTED

I have already bought this box as I was told this was the absolute best box for my truck, I am trying to figure out what subs would get the loudest in it. It has already been said that the sundown sa-12's will fit and sound great, but im wondering with the box specs would I be better off going with a different sub? Im not opossed to making some reducers and going with a different size sub either lile a sa-8 or something which may get louder due to the minimal air space etc. What do you guys think? The box should be here by friday and sundown has a dealer who has all lines of their subs on my trip home from work Saturday.

Thank you in advance for your help.

Box specs:2-12" VENTED SUB BOXAIR VOLUME: 1.55 CUBIC FEET PER SIDE*DIVIDED

PORT/VENT TUNE FREQUENCY: 35*Hz

MAX FRAME SIZE: 13"

MOUNTING HOLE SIZE: 11.125"

MOUNTING DEPTH: 7.25"*WITH A 6.5" DIAMETER MAGNET

Sundown sa-12 subs show 0.14cu.ft displacement so I guess that would give me an ending internal volume of 1.41cu.ft of air space per side in the box. Is that enough to make the sa-12's get loud?

Very sorry, it said database error and I hit refresh 3 times then hit back and vlicked on subwoofers up top to make sure I wasnt double threading and sure enough, the damage was already done and I tried to delete the extra threads but couldnt find the option. Im sure a mod will clean it up for me, sorry mod... now any suggestions on the thread topic?
