Box Help

[Curtikins]

Hello, i currently own 2 ZV3's in a ford expedition, and im curious what a good low tuned(28-30 hertz) box dimensions should be. Sundown posted a box on there website but im just curious if there is anything better

We can't tell you if something will be better cause all the variables in each car are different, there are general dimensions that work in a wide range of cars, but if you wan't something louder then you'll have to build it and test it.
