A box doesn't depend on your vehicle, it depends on your subs. Making a "Perfect" sub box is very hard! Like professional hard. You need to get how many squar feet cubed your box has to be and go from there, and you have to have the box a special shape. Try looking on the internet they may have some dimensions. It may be alot easier and probably cheaper in the end to get someone to make one for you professionally. You'll most likely get better sound qualitly out of it. But if you have your heart set on trying it, it can be pretty cool thing to do. =)
Enjoy!
And keep pumpin' that bass!
