My first time using sundown. Im looking for a street box ported or a 4th order box. Just need internal cubed for each. 4th order sealed side and ported side. And square inch port for each. For know I will be running it at 4 ohms and will have 1500 watts for rms. It Will be in a 2002 4runner. Sub again will be a X15 D2.

I tried entering the specs into winISD gave me errors and wouldn't calculate a box for me?
