Im designing a box for my 18's right now, and it seems the biggest port i'll be able to fit has an area of 165.75 square inches. Will that be decent for a pair of 18" RE SX's? I've never used subs this big before.

I'd try to get closer to at least 180-200sq.in. of port, but it depends on how much power you have to, more port area the better IMO when it comes to a box this large...

16cuft 210sq.in..
