[moto211]

here you go , 2 4inch will be 14"long or 2 3inch will be 7 " long i would go with the 4" good luck

IMO, you need +3 4inch ports.

Two is going to choke that sub.

thanks guys! I wanna stick to 2 ports though would 2 6 inch be too much?

[moto211]

yes 3 would be better if you can fit 25 " of port or one 6x6 square would be 18 inches long , a few options to go with

Do you already have the box built and you're wanting to add external aeros? If not I'd just do a slot port. Aeros just get too long if you're wanting to tune low while using a good amount of port area. And you'd save money with a slot port as well.

Ya its already built or I would have done a slot port. Its in a car and firing into the cabin. I have two holes in my rear deck on eather side of my sub and I thought it would be nice to get two ports aiming threw the holes.

Ive never seen a square port only aero ports and pvc pipe.

ok 2 6 inch would be about 151 " so thats no going to happen . 1 6 inch is 15 inches with a port area of 28 square inches , but 1 7inch port would be 24 inches long with a port area of 38 square inches , a 7 inch port has more area than 3 4 inch ports , imo i think a 7 might be your best bet
