Okay well my previous box would not fit into my car, so this time I measured correctly and I am going for a slot port instead of my previous PVC vents.
I have used BB6 a bit to get the size and what not, but it does not calculate if there is a bend in a slot port. So I was wondering if someone would be so kind as to let me know if all of these numbers are correct (since I came up with them on my own basically, from bb6's dimensions for my needed cubic size).
Red: 16 x 23.25
Purple: 16 x 28
Blue: 16 x 20.5 (x2)
Yellow: 16 x 16.5
Green: 16 x 13.25
Teal: 28 x 22 (x2)
It should come out to 17.5" H x 28" W x 22" L
Port is 16" H x 4" W x 30.5" L
Anything that is wrong please correct me on, or any suggestions on a different size/design just let me know.
