I think the rule is big box, and higher Hz like 41 and up..

There is no magical formula for making an SPL box. Testing differen't enclosures in your vehichle is what to do. Do you know what your vehichles peak frequency is? Find a shop or person with a Term Lab and find your peak frequency and tune your box to that or around that frequency .

x2, the best advice given; plus lots of tuning/tweaking and adjustments to car and equipment to get numbers (it will take a lot of patience and time but it will pay off in the end). Good luck man.
