[QUOTE="THATpurpleKUSH, post: 8607911, member: 615398"] 1. For clearance from the end of the port to the wall of the box allow no less than half the width of the port, personally I usually go no less than the width of the port. 2. If you are chasing numbers yes location of the port can matter, for your application it's not as important. Use either the same face the sub is on or fire the port out the top of the box. It's hard to tell but from the pictures if you rear fired the port toward the hatch there might not be enough room between the mouth of the port and the wall of the hatch. If that space is at least half the width of the port then it would be ok to port to the rear. 3. If the ends of the port are flared then the length of the port needs to be extended by the length of the radius of the flare on each end. For example PSP 4 inch aeroport kit is 18" long overall but only 17" is usable. If there is no flare just use the full end to end length. I like to use a piece of pvc to mount the port tube to then bolt the whole assembly to the box. It's easier to swap out different length ports that way. [/QUOTE]
