[Ineed A Box]

are you using prefab boxes?

if not then in plain english.

dimensions =

how wide is your trunk?

how tall is your trunk?

how deep is your trunk?

if you want to do 3.5cu ft. per sub and tune it to say 35hz then we need the max dimensions of your trunk or hatch or whatever you have so we can help you figure out what you want to do.

"I think that they are 17" height/ 30" depth/ and 33" width i have to make sure"

17" x 33" x 30" = 16830 divided by 1728 = roughly 9.7cu ft.

thats over 4.5 feet per sub.

i'm gonna give you some dimensions just because you sound really confused.

build your box 17H x 24W x 33L and it'll give you roughly 7.7cu ft. once you take the port area out of that and the sub displacement you'll have about 3.5cu ft.

separate the chambers and on each end (or in the middle) have a port for each chamber.

now your port for each chamber will be 15.5" tall X 2" wide and will extend into the box 16.32". this will give you a tuning frequency of roughly 33 HZ.

i hope this kinda clears stuff up for you.

if you will draw up a picture on paint or something of how you want your box i'll help you out some more.

I want something like this.

That is the top view; and i checked my space in my blazer and it is 33" depth/ 37" wide/ and 16" tall. but i want to leave about 7" on the side for my spare. so about 30" wide. And if the pic dose not work it's like the box that steven mead for that explorer on the built page, but with 2 port's. and yes you are clearing some stuff up for me. See i know alot about sub's amp's and wiring, but not to much with boxes.
