ok so i havent been on here in a while, but i had mazdaspl design me a box a long time ago and he kinda messed up on my 4 18 design port up. The way he did it they are only seeing like 3 cubes per woofer. The subs are 4 18s FI BLs off one t4k soon to be 2 t4ks runnin at 2 ohms. thing is im sure im choking the shit otta them now. Me and him talked for a bit last night and figured out a new box design but the thing is if i use slot port on bottom i can only get like 3.6 cubes per woofer and 4.1 cubes if i use aeros. The thing is aeros are costly and i have already built 2 boxes that have cost me alot. First box was just 3 18s and sound way better, than with the 4 in my new box port up. So basicly im just wondering if anyone has ran these woofers with that kind of space. There in a 04 explorer. My MAX dimensions are 23 high, 45 wide and 37 long. That and to get 3.6 or a little more cubes i would have to run one baffle but just double up on internal bracing. Idk thinkin i should just sell the one 18 and go back to the 3. But i really want to build a new box just to see what it would sound like port back instead of up. I mean its trial and error to see what works. Bad part is i should have tested my box that i have now with the 4 before i wrapped it and did alot of fiberglassing cuz now im going to have to throw away the box and be out like 400 or so bucks.
here is my box that i have now
here is a pic of before i wrapped it when i was doing resign 45s and fiber glassing.
