If you add the end of the box the way you have it, the box will be 39.5" long. Instead, either the make the sides 1.5" shorter or the ends 13.5 x 15.5. Take the internal dimensions:
36.5 x 15.5 x 13.5 / 1728 = 4.42
Sub displacement is .07/sub = .14
4.42 - .14 = 4.28

Make a port in between the sub that is 13.5" tall and 1.5" wide. It will be 13.75" long and this will tune it to 28Hz. Let me know if you need a pic.

so the front part for subs will be

2x-18.25"w x 13.5"h and port in between 1.5" = 38" is this correct?

and port 13.5" h x 13.75" long tuned 28hz.
