I'm gonna tune to 33hz. Not sure how much cu.ft. i'll have. I think my measurements are 37" wide.. 28" deep.. and however high. Thats the amount of space I have in the blazer. Haha. I know the box definitely has to be 37" wide if I do 6 on top.

 

8 12s are going to require 10-13 cubes if you port them, before port displacement. you're not getting anywhere close to that with those measurements. even if you built it as high as the ceiling. if you want 8 12s you'd have to clamshell, i don't even think a wall will have enough surface area on the baffle to have 8 12s.

you'll have to run them sealed

 

sealed doesn't bother me. what measurements do you think I should do if I do it sealed? And should I do 4 on top 4 front?

 

you'd have to do something like that if you stick with the current measurments

 

so lets say I did 36 wide, 28 long, and however high. I should do that big of a box sealed? Haha. Aren't sealed boxes usually a lot smaller..

 

36x28x17 will net you 8.2cuft, by the time you brace it (you better or you'll have retarded box flex) it will probably end up close to 7 cuft. which should be fine for all of those subs sealed

 

It'll be built right. Haha. My dads built boxes before and if I really need to my uncles friend does amazing work. He'll do anything custom. Haha. But if I ask him for a sealed box i'm sure it wouldn't be too pricey.

I've never built a box before.. So it'll be a learning experience [= Thats basically what my Blazer is for. To learn with. Haha

Also, that HiFonics Hifi2500 should be fine for the subs right? Or would you recommend something different..

 

how are you going to run all of these amps on a stock electrical system?

 

I'm not running it off stock.. I'm not retarded.. Haha

I'm gonna put 2 yellow tops (hopefully if they dont cost too much) in the back and run either a larger alternator or dual alternator set up. Then change wires accordingly.

I just wanna know what amps I should use for what.. and I'd like to keep everything the same company if possible [=

 

are you dealing with 10 inch p2s or 12 inch p2s? and, why such a narrow box? mine is 32 inches only because i have a spare tire in the way. if there wan't that i'd be about 40ish inches no problem
