I'm building a sub box to fit a specific area. I can alter the volume of the box itself but the positioning of the port has to be opposite from the sub. As in sub facing the trunk with the port coming up between the seats. Is this way going to make SQ suck?

I could also, I suppose, face the sub toward the seat, but it'd be basically up agains the back for the trunk so I don't know if that'd be good.
