got another box made up

Some will tell you that program is not very accurate.

Just use Winisd and rocford fosgate box tools.

Then just transfer it all over to paint or what ever. I know it takes some time but gets the job done.

Here is one I did for my 15" btl

4.5 cuft @ 33hz @ 90 square inches of port area.

It not 100% finished.

I have to figure out bracing displacement and what not but just a ruff 5 minutes and got a good idea.

Few more and it will be done.

Is 36^2 enough port for those subs? If not change the xmax to get the desired port size. I've built 5 boxes with that program and they've all sounded fine.
Use about 12-16 square inches per cubic foot.

I like to use alittle more on a sub that moves alot of air.
