yeah how does that sound with a port coing out one side. I'd really like to have it up the middle but I know i'd have to stagger the drivers to make them fit.

cool i see but i have 68.5 wide 37.5 high and i dont wont to go no deeper than 33 deep it will probably be 53 wide 37 high 31 deep that gave me 31.25 so 30 cu ft is it after the drivers then got some bracing

how do you come up with that im trying to learn so would 20x20=15.5 Port Length right would that be enough thanks

it could be either now that im gonna gut the back out i got a lot more room i was thinking 31 cubic feet after though

come on now 156 pep looked 2 replied

ku40 thanks for the help. Helped me out alot. Couldn't figure it out I must have been brain dead. But now the box is gonna be alot wider than I thought. Gonna strip the back of the truck down and that will give me close to 70" wide but the same heigth. hopin to put a 15x20 port in the middle at the bottom and that would give me a port length of 10"?. gonna be using for daily but would like to take it to some shows and want to open my own fiberglass shop so I want it to look good for customers.I want it to be really loud but sound good. That's why i'm trying to stay in the 33 hz area. i've never messed with 18's or a ported box. This is a first for me. I want to be able to pull the port out and go to 40 some hz. Been reading lot's of other posts to get ideas but there doesn't seem to be too many people that have done this in a explorer or just run a wall with 4 18's. i'll figure it out one way or another. any help by anybody is appreciated about how to do the ports and the optimal cubic feet that i should try to reach. thanks, bigjay

i have read it you spent a lot more time doing your test than i did and had a lot more equipment to do your test. i see your point. my bad.

check this out lol

sounds like you had a better test than i did lol

distortion blows subs up butt not as fast as way to much power.

its too much power that blows subs and it's distortion and i've never broke in subs. I've gave them hell from the first day. I'v still got a set of jl's that are 7 years old.

if you find 1 let me know your box would be pretty easy i was looking at TurboBass Express

If anyone has tried this could you tell me what you think of it? I'm trying to build a wall that is all funky shaped. Trying to smash 4 18's into a Ford Explorer. found this program but would just like to know if anyone else has used and what you think of it. The bottom is 37" deep x 52" wide then go to 33" deep x 18.5 " high. Top is 33" deep x 52" wide 18.5" high Grand total of 37" tall x 52" wide and the depth. Trying to utilize every bit of room I can so I can still have room for batteries and amps. Plus the ports gotta go in there to. Any help on any other programs or any ideas would be appreciated. Got it drawn out on paper. Kinda to scale it down to where it will be the same. The only chunk of cement i could use to draw on is the road lol.

O I see that makes a lot of since.duuuuuuuuuuuuuuuuhhhhhhhhhhhhhhh I do appreciate it.
