Fi Bl 18

[basshead445 0]

Hello all, I am wanting to purchase a bl 18, but possibly a q 18. The dimensions of the box i can make are around 16h 32.5w and 22d with the sub facing up. I have a couple of questions, first, does it sound better to have the port on the side of the box or going along the bottom? Secondly, would that be enough space, i calculated it to be around 5 cubes after speaker and port displacement. Lastly, this is going in a celica gt-s hatchback and i was wondering how much room do i need between the back of the car and the front of the box? I think with these measurements i left out like 6 inches between the two. Any help is appreciated.
