I have a ddx d2 15 dual 2 ohm and I’m needing 4th order specs

Need to know sealed volume, ported volume, port area and length! Running a 1000 mono block skar amp at 1ohm on 1 15. Any help would be appreciated. It’s going to be in the bed of a sxs so we were told 4th order would be best to exposed elements. Thanks again.
