Port design question

[jj53913 10+ year member]

I am looking for some help. I am looking at building a box for 2 subs with the port centered in the box. The port and subs both facing forward (going in an ex-cab pickup) The port will have to be longer than the box is deep so I have to figure out how to make the port split. If you were looking down on the box the back of the port woult look like a "T" I guess is how to explain it. My question is say the opening is 10"x10"=100 cu.in. when it T's to the left and right would I want the port to measure 5"x10" on each side to finish the port length out or does it stay 10"x10"? Thanks for the help

Yep, once it gets to the back (or the 'T') it'd be 5"x10" for the two individual ports

Thanks now I have to figure out some other way to design the box. My port ratio will be 8.1 to 1 after it T's wich I think is a little to much isn't it?
