tuning box

[shadowm891 10+ year member]

right now i am running a single sundown audio sa-10 off a jl audio 300/2 amp at 2 ohm in a 08 nissan 350z. the box spec's for the sub woofer are w25" x h9" x d14.5" tune to 35hz. I really like how the sub sounds in my car right now but i was thinking about building me a 2nd box for spl only just for sh**'s and giggles to see how it would turn out in my car. Now my only problem is i'm not sure how high should i tune the box.
