I need to make a box for my 12w7. Dose any body have any designs for me.

well you need to tell more...

1. Whats the dimentions of your trunk? Or whats the MAX sizing you will go(Height, Width, Depth)...leaving room for tools, groceries, etc
2. Do you want ported, sealed? If you could list the reccomended sizes
3. What kind of wattage do you have for it?
4. What "shape" do you want? Rectangle (wide, mainly fits the car), or a mostly cubic box?

I really don't care about the dimention. I have an explorer so i have room. I want it ported. I have a BX1500d so about 750 watts. Whatever the best shape for one.

Well whats your width of the xplorer...43"? And whats the height from the floor to the rear seats??

JL 12W7

Usefull for you...
Mounting Hole Diameter: 10.5 in. or CUTOUT

Sooo, whatcha wanna do is make a box that is

Width = 27.5"
Height = 14.5"
Depth = 12"

So that the internal dimentions are...

Width = 26"
Height = 13"
Depth = 10.5"

This will give you 2.05cuft minus the displacement of your sub (.14cuft)...minus the displacement of your port (.1354cuft) finishes you off with a which ='s 1.775cuft

So in your box you will have a port thats the height of the box and will wrap around 25.16" Heres the pic http://memimage.cardomain.net/member_images/8/web/836000-836999/836385_8_full.jpg

Hope this helps ya...
