holy hel l !!!!!! nice set up, you gotta put up pics after it's done
anyways, listen to the previous suggestions, two layers of 3/4" is more than enough i've seen a 100lb cerwin vega stroker pro setup using a dual layer 3/4" box

lol thank you man. This setup is going into a really tiny car= 1994 Mazda MX3. Sure i'll post pics.

So i'll just double the whole board where the sub sits, Can do.
