you need to give measuments of the port. if it's a slot port, how tall and how wide is it.

its 3.375 tall and 41.5 wide. and its 25.75 long. i used the re calculator. i got the volume of my box and figured out different measurements to put into the re calculator to get the vent size

you do realize that port displacement is going to push total box size to larger than 8.3^3. maybe you knew that. you should be ok with the port.

it would probably be better to put all 4 subs pointing back, or all 4 forward.

the side where the vent is is the passenger side. it'll be a wall. so i want to see some of the subs on the wall. then the amp will go on the back slanted part

not the best option in terms of how it will sound.

If nothing else, I'd at least move those two extra ones to one on each side of the box
