port placement in a truck

just curious on design for this kinda appication. rite now i have a single 15" firing forward with port on drivers side firing forward as well. I am restricted to only firing the subsforward due to space issues. I wanna drop one more 15 in and was thinking of having both subs firing forward( behind each headrest) with a long port on the bottom of the enclosure face firing forward also. Will this work, or will i run into compression issues or anything like that...

If your port is 8 inch round port, allow 8 inches of clearance to closest object in front of the port. If sloted like 2x12.75, allow 2 inches (the short part) of clearance to closest object in front of port for the full 12.75 (the long part) inches of the port.
