Need help with box

[SchnuppeR]

I need some help designing a box for my new subwoofers.I bought 2 Alpine Type R's 12inch(SWR-12d4, 5th gen) to replace my 1st gen type r's. I listen to mostly house/trance/dance music with the occasional rap. I am purchasing an AQ2200D amp to power the new subs(replacing my kicker kx600.1)

The box can be 14 1/2 inches height and 34 inches wide.

Thanks in advanced and happy holidays SMD members!

Here is a suggestion:

Enclosure Specifications:

Fb = 33 Hz

Vb = 3 ft^3

External Height = 13 in

External Width = 33 in

External Depth = 21 in

Port Width = 3 1/2 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

2x Front = 14 3/4 x 11 1/2

2x Front Internal = 13 1/4 x 11 1/2

Back = 33 x 11 1/2

Left & Right Sides: 19 1/2 x 11 1/2

Top & Bottom = 33 x 21

Shared Port Internal Assembly Parts:

2 x Front to Back = 17 3/4 x 11 1/2

2 x Extension = 4 1/8 x 11 1/2

Assembly guide (generic dimensions):

- 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 trunk boxes built outside the car 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's subsonic filter to 28Hz is suggested.
