Hey everyone, my cousin gave me one of his old subwoofers and amp, but i need to get a box for the sub. It is a ten inch alpine sub that needs around 1.2 cubic inches of volume if it's ported. I will leave the specs in a link below. The truck i want to put it in is a 1998 f150 xlt extended cab. It has the seats that flip forward with the metal plates underneath. There isn't a whole lot of space under there so i want to make my own. If you can, post the specs of any builds you may have done. Any help is appreciated, thanks http://www.crutchfield.ca/ProductDet...3&Show=ExtInfo
