If you make it with 3/4 mdf which you should its 3.38 cubes before displacement

thanks for the link... how do you find out what it will be after displacement tho...

find out how much displacement your subs/ports/bracing take up and subtract it from the gross

Use simple math.

For the rectangular part

LxWxH

For the triangle

(1/2)(Base) x Height x Length

the only problem with is i have not built the box yet.. this is just how much room i have behind my seat and im trying to see how many cubes it is to determine what subs i can get..

edit- im a noob, as you can probably already see

The subs you buy will have it listed as displacement

ok so now i have another question.. i am most likely going to run 12" memphis prs sealed.. should i make a seperate chamer for each? and should i poly fill the box?

I would run 10s ported over 12s sealed myself

yeah, but ported takes alot more time and skill which i dont have at the moment.. i planned on putting in the 12s sealed and then down the road building a ported box...
