Alright Im horrible at math. I have been since the 6th grade.
This is going in a 2008 Dodge Caliber.
I want to take my pair of ID8D2V3s out of the ported box they are in and build a sealed box that is smaller so I can gain hatch space back.
I want to go with .40-.45 cubes a piece so .9 cubes total. Mounting depth on each sub is 4.75", total diameter is 8.375", screw hole diameter is 7.125", displacement is .04cuft.
