box help SA-15

[gmc123 3]

I am building a ported wall for 6 SA-15s and im having a hard time figuring out a good volume for the box. Its going to be a dailly driver so I want good sound tuned around 35hz. It will be ran off 2 2600w soundstream amps. I plan on listening to rap and bass tracks.

12.5-13ft^3 would be a start and tuning at 35hz is a good choice.
