about to build a ported box outside of the exact dimensions from the factory. the question i have is, I have the recommended internal volume of the box and the recommended dimensions of the port. do i include the volume of the port when calculating the volume of the box? or do i calculate it separately... the internal volume is 1.25 ft3 and port size is 3"x10.5" if you wanted to help thanks fellas.
