i dont know what measurements you are trying to find... the12volt website will give you dimensions, and exact volume for almost any given speaker on the market.you only need to punch in your woofer, and it will give you length, width, and height, along with port size. it is up to you to decide what will fit in your car, and go from there. (i have designed a 2-12" enclosure to fit between the back seat, and the trunk area for my 65 coupe, the two power amps, and crossovers will fit on the back of to box)
