help on port size

[mtxfan4life]

i have a 18 inch sub its in a 6.7 cu ft box after sub displacements. its in the trunk of a car. im wondering what would difference be if i had a 6in-- 8in or bigger/smaller slot port on the box. im thinking going with a 6 inch port. what would u do?

port widths mean nothing when there are no measurements to figure it out.

ok see thats why im asking. measerments of the box? the box is 35w x 14.5t x 29d. and would it be better to use a aero port? ive never done thisam just trying to learn here

6-8x 13?

yes it would be 13in tall by 6 or 8 inch wide. i know how long it would have to be. i just want to know is there a sound difference between a 6inch port or a 8 or 10inch port?

6 inches would be 30" long
