hi all i recently purchased a fi q 18 to go in my 95 4 door explorer and now i need to come up with the plans for the box so i can start building. my maximum dimensions for the box are 40 wide by 40 deep by 22 high. i am a some what skill full carpenter but i need help in the tunning area. also if anyone has a similar setup to what i will have and still has the plans lying around i would greatly appreciate it or if someone could use or tell me where i can find a box calculator to spec out this box that would also be greatly appreciated. oh and lastly i am open to using a t line but would need the plans to build one.

thanks
