No Subs up....PORT BACK BUT UPRIGHT on left or right end of box....

Is there room to slide the subs hard to one side of the enclosure and move that middle port over to either side upright...Put it in the opposite side of the enclosure where you would like the most pressure up front....in other words port on drivers side = more pressure to the passenger side......I have done several enclosures like this in SUVs and they all POUND.........good luck

yes if your port is in the center like a lot of prefabs.....its only touching the top and bottom so that is 2 in Torres

The common port walls thing wants to know how many sides of the box will also act as a port wall as well....like a slot port on the end of an enclosure is using 3....

I tune most of my enclosures in the range of 34-35hz and they sound amazing on most anything I play....My Ascendant Audio Havoc 12" doesn't have any problems finding the low notes in the 34hz box it is in.....good luck

What final OHM LOAD are you running? You need to get an amp that will handle the load and back it up with the proper electrical. Good Luck!!!!!

I came up with the dimensions you gave a box that nets 15.49 cubes (3.8 per sub).....tuned to 34 hz with a port that is 5.5"h x 35.5"w x 14"d.....that is 12.61 inches of port per cube!!!!.......Thats with .60 sub disp, .30 bracing, and a double baffle......Box built with 3/4"

NICE!!!!!

I would suggest going with 3 subs unless you want to spend tons of money on AEROS.. I just played around with my box building program and a SLOT PORT is just going to rob too much valuable air space to get any kind of PORT AREA out of it. If I can help in any other way let me know.
