Dual sa 15's Box Design Help

[Typhoon]

Hey guys I just recently purchased 2 Sundown SA 15's and i was trying to make my own box but I am not sure if it is good or not. Any tips or help would be great.

Thanks!!

Here is the link to my design - http://prntscr.com/4x7lv2

net area is to big and you need a lot more port area

i would go with 7.5 cubes with 14" of port per cube

A. You're a little high on net airspace. Not high enough that you should be in trouble unless you're throwing a LOT more than rated power at them.

B. I think you're way short on port area. How did you figure 60 square inches would be enough for two SA15's. That is concerning, as too little port area will strangle those subs.

I was planning on putting a brz2400 amp in and wiring it to 1 ohm would that still be too much airspace?

Is this better with port area? http://prntscr.com/4xdyys

Only advice would be to throw a roundover on the port with a router (if you have one with a roundover bit.). Otherwise, you're right there in the ballpark of what I would've tried in your place.
