box design for 18btl

[jft32 0]

Need help with box specs and design for an 18btl. It will be going into a 2002 jeep grand cherokee. The space that I have available is 40x23x16 (w,d,h). I want the box to be tuned to @30hz. Sub will be powered by a planet audio bb2400.1 I would like the sub to be facing up with port firing back. Any input that you guys can give me would be greatly appreciated.
