Can someone help me find what my box is tuned to?

[Anonymous 10+ year member]

I posted a thread before but the measurements were wrong i forgot to subtract the thickness of the wood. Actual measurements w/o port are: 15.5"H x 38.75"W x 32.5"L. Port is: 6"W x 32.5"L x 15.5"D. I have 4 Orion P Series 15d4 i do not remember the T/S Parameters but they can be found at http://www.orioncaraudio.com. Thank you for any help. And hell if someone could just give me a formula i could probably find somwhere around the tuning but i do not know where to begin. So please help.

When my subs are upfiring then the width would be from driver to passenger side right? And length would from hatch to back seat? Or do i have them confused?

I got 24hz which seems low to me, 406er got 28hz, and the place that built it says 35hz. But i have gone through the formula numerous times and i get 24hz. Once again the net volume is :15.5"h x 38.75"w x 32.5"L, from my hatch to backseat.Port: 6"w x 16.25"h x 32.5"L, from hatch to backseat
