creating ported box {help me}

[Nore474]

I am going to replace my sealed box with 2 MA audio XL 12's into a ported box with them

I have to make the box volume 2 cubic feet for each sub how does this sound
lentgh 41"
hieght 18"
witdh 14"

I am not to sure where i should place the Ports?

I have those black prefab ports with a 4" diameter and the port lenth is 6" i am pretty sure that is to short I think i need it to be 10" I can make that longer by just putting pvc pipe over it right? or should i just use pvc pipe?

This box should fit into my maxima right?
can you guys give me some pointers!!! please

thanks!!!

Add an extra 2 inches in length on each end, and add the porting all up and down the height of the box. I have one JL 12, in a ported box and it has a single port, up and down one side.. it should work the way I'm thinking..
