Alpine type R 15' box help.

[JesseyMclame]

My buddy bought a box from his friend, and it was a piece of shit. I have half a sheet of MDF, and wanna build him a ported box. It's going in a late 90's Chevy 2500 ext cab. If possible, port up and sub up, and if someone could provide a visual for me, that would be great. I guess max dims would be 17" deep, 18" high, and 28 wide. I guess tuning preference would be around the 34 hz range ? Someone please help me out, thank you all.

Ok here is a suggestion:

Enclosure Specifications:

Fb = 34 Hz

Vb = 3 ft^3

External Height = 18 in

External Width = 28 in

External Depth = 17 in

Port Width = 2 3/4 in

Cut Sheet List:

* All Dimensions in Inches.

* Wood Thickness is 3/4 for all Parts.

External Enclosure Parts:

Top & Bottom = 28 x 17

Left & Right Sides = 15 1/2 x 16 1/2

Front & Back = 28 x 16 1/2

L Port Internal Assembly Parts:

Top to Bottom = 13 3/4 x 15 1/2

Extension = 7 3/4 x 15 1/2

Assembly guide (generic dimensions):

Let me know any questions.
