Im building a new enclosure it will take up most of my ext cab. The dimensions are 54" L x 21" H x 17" D. My subs will be sitting on top 2 SX 15"s I know with a 17 inch depth its going to be tight but I can get the job done. The enclosure will have two seperate chambers. I want to put a port in for each chamber and the chambers to sit on top next to the towards the middle. I dont know how long to make the board to go inside for the port and I dont know how large i should make the rectangular ports.

That looks like it will work. It's about 3.7 cubes net per side tuned to about 33hz. It has about 50 square inches of port per side as well.

you have the dimensions for the interior boards for the port. thanks dude. thats awesome. its going to be somewhat shaped differently because the ext cab of my truck rises up in the middle about 4 inches. So its going to be like the bottom half of a H if you follow me. this is just the bottom its 54 inches total but its going to be 18 inches then rise up 4.5 inches, then go another 18 inches across, then down 4.5 inches, then another 18 inches to equal 54 inches.
Im changing the height to 18 inches also i dont need a 10 cu foot box lol

If you're going to have the bottom change its height, I would NOT suggest going with only an 18" height total.
You will be losing a lot of airspace by going with a max of 18". I would NOT recommend doing it. 3 cubes per sub is a little small for the SXs.
Let me redesign it but with the 21" height.

Here is what I came up with:
Let me know if you need any more shots or if you want the sketchup file.
