Sa-12 spl/daily box

[sundown escort]

I have a Sa 12 D2 running on 900 rms. The box it is in is 2ft^3 with a L port tuned to 35 htz. It is in a small two door trunk car, no clue what the resonate frequency is.

Dimensions i have available are 27w x 13h x up to 25d

Im looking to find an optimal box size and port tuning for spl/daily use.

Any info or opinions appreciated.

Thanks

(If i need to give more information let me know)
