HELP please Airspace calculations for irregular sub box
Hi, guys, I need some help figuring out how to best calculate the airspace in an irregular shape. I am building 2 custom enclosures from fiberglass in the trunk of my 97 prelude. they will go in the rear corners closest to where you open the trunk up. I have 2 12"Kicker l5's and i know they both they each have a kicker recommended min .66 cubic feet and max recomended 1.0cf but it is a weird contoured shape. If anyone can help me figure how it is best to calculate odd figures like that it would be greatly appreciated.
Yes i know a standard shape would be l*w*h usually in inches and divide by 1728 for cubic feet. No so easy when dealing with indentations and such.
I am sure they taught this in school and it was probably chalked up to one of the useless things i thought i would never use and never committed it to memory.
I googled the hell out of it and found no good solutions for irregular shapes.
Searched the forums turned up nothing as well
