Looking for specs on ported box for 2 x 12 DC Level 2 subs.

Thanks

Post max dims for a box, vehicle and amp models and type of music you listen.

[akatreyt]

height 13 1/2

width 33

depth (top and bottom) 12 1/2

vehicle dodge charger

amp sundown 1000d or dc 1.2k

mostly rap

Here is a suggestion, had to go deeper but I could go wider or taller if the box can't be that deep:

Enclosure Specifications:

Fb = 33 Hz
Vb = 2 ft^3

External Height = 13.5 in
External Width = 33 in
External Depth = 14.25 in

Port Width = 2 1/4 in

Cut Sheet List:

* All Dimensions in Inches.
* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Front = 30 x 12
Back = 33 x 12

Left & Right Sides:
Side 1 = 12 3/4 x 12
Side 2 = 13 1/2 x 12

Top & Bottom = 33 x 14 1/4

L Port Internal Assembly Parts:

Front to Back = 10 1/2 x 12
Extension = 13 3/4 x 12

Assembly guide (generic dimensions):

Important notes:

- The 45s if you want to do them are 2 1/2" wide except the one/ones inside the port, if you want that let me know.

- All boxes built outside the vehicle need to fit in their way in not just have the right dimensions.

- The port needs 3 1/2" of free airspace in front of it for proper operation.

- Setting your amp subsonic filter to 28Hz is suggested.

Thanks!!!

Hate to ask this but could I get a schematic of 2 10s instead of 12? The box needs to be smaller so maybe 10's would work better.

[Joe X]

So I changed it for a couple of L2 10, hope you can live withe new size.

beautiful, thanks. I do have a few questions

Left & Right Sides:

Side 1 = 12 3/4 x 12

Side 2 = 13 1/2 x 12

are different lengths?

Also is there a way to make the port in the middle like the 12' box?

[Joe X]

Yes, there ia a 3/4" difference check the sketch to find out why, I would not recommend port in the middle for a small box like than when tuning low, it would need to take two turns each side and it therefore a loss of port efficiency, in addition to that, the box would need to be deeper due to all the extra parts needed to do the port.

I don't know how Joe X gets these up so fast, true hero to many of us in need of designs
