Default 8 15's 4th order wall possible?

im gonna start a new build in the spring in a blazer and im thinking of doing a 4th order wall kinda like this


im thinking about using 8 15's. i know there is enough physical space mounting wise, but im not so sure airspace wise. do you think i'll have enough airspace for that? (will be gutting the entire interior behind the front seats). i might have to find a cheap tahoe lol. also im leaning twords (i cant spell lol) aq sdc2.5's because i love the ones i have and their price. are they a sutible driver for a 4th order? i would like to design the box myself but have never done a bandpass before, what do i need to know to calculate it.
i am aiming for 150+ on music low as hell.

thanks for the help!

But to be honest its sort of hard to design a 4th order if you dont know what your doing and if its not a good design it will sound like ass so i would suggest u invest the 5-25 bucks to pay a designer that knows what he is doing and that way you know it will be a good design and wont sound like ass and wont be a waste of wood just saying.

Yes, it can be done like that. That way is how I have mine setup with my 12 12's. However, SDC's suck for 4th orders. Too stiff of a suspension. I'd reccommend more 4th order suitable 15's if you are going to go that route. Sundown SA-15's, Or Obsidian 15's would fit your application very well.
