Help With Airspace

[reinke]

i have some 10's that i am gonna put into my wifeys car soon. (look out for the build) i can not find any specs on them at all. i am gonna do a sealed box for sure. i need to know what airspace should i use for each. there will be 4 10's total. each set of 2 will be powered by a SSL 2f800. i would also like to do a fiberglass box and was wondering how do i determine the airspace of one. do i just build it and then make it bigger by adding a compartment, or if i need to make it smaller then i would just add something to take up some air. thanks for the help

i would say a safe guess is 1 cubic foot per sub. If you have to, build the box bigger and make smaller by adding stuff [bag of sand with resin, expanding foam with resin. Its hard to get more space once the box is built. You can determine volume by using packing peanuts [go to fed ex and ask to borrow about 6 cubic feet worth. explain what you need if for and promise to bring it back exactly as it is. no guarantee, but it worked for me]

so i should shoot for 4 cube total if i do not fiberglass. if i do decide to fiberglass how do i make the box so it is right around 4 cubes. the only part of the box that would be MDF would be the bottom and the mounting rings. everything else is gonna be fiberglass. i am kinda going for a GP2K2 look only alot smaller.
