I Need an enclosure design please

[Brandon Mendoza]

For 2 SA 12's, 33-34HZ tuning. Will be a daily music setup (mostly decaf) powering them with a Massive Audio N3 at 1 ohm (1200 to 1300 RMS hopefully) going in an 01 Expedition with the 3rd row out so space isn't really a problem just keep it under 15 inches tall if you could so its below the window line.

Here is a suggestion:

Enclosure Specifications:

Fb = 33 Hz
Vb = 4 ft^3

External Height = 15 in
External Width = 38.5 in
External Depth = 20 in

Port Width = 4 in

Cut Sheet List:

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

External Enclosure Parts:

Top & Bottom = 38 1/2 x 20

Left & Right Sides = 18 1/2 x 13 1/2

2x Front = 17 1/4 x 13 1/2

Back = 38 1/2 x 13 1/2

Shared Port Internal Assembly Parts:

2 x Front to Back = 16 1/2 x 13 1/2
2 x Extension = 4 1/2 x 13 1/2

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.

- This box should be operated around subwoofer(s) rated power. If that´s not the case, let me know.

- The port needs 4" of free airspace in front of it for proper operation.

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

That thing looks perfect, thanks. Should work great in my application and with the power I'm running which is right around RMS to each sub 600-650 per sub
