How many Cubic Inches??????
I am planning on building a down firing ported box for a polk 10" 4 ohm sub. Does anyone know off the top of their head how many cubic inches are need for this application. I am going to be putting this in a 96 full size bronco in place of the current center console between the front seats. Any help would be greatly appreciated.
