Might have a little too much port area per foot. I'd try re doing it closer it 14 ish. I had 19 per foot and it was loud but very narrow band width around tuning. When I had 12 it was a lot more musical. Could've just been my truck tho. Maybe someone with more knowledge will give u some better advice!

My friend has a box for his sundown sa 12 @ 12 per foot and its pretty damn musical but doesn't have a good amount of output. Like its loud but I think 14 would be a lot better. My box for my 15 is at 14 and its got good output ans bandwidth. Pretty happy with it id shoot for 14

[Dan2427]

You're right Dylan. I just went back and looked I was at 13.9. So I agree shoot more for 14-16 range!

you need to change the "Common Walls" to 3. You are just doing a port that uses 3 walls of the box for port walls right?

and you might want to change baffle thickness to .75 unless you are doing two layers of 1.5 mdf for the baffle. Torres automagically figures the thickness of the baffle when you put a number in the "Extra baffle" field. Also, extra baffles are figured inside the box not on top.

Here is a suggestion, recommended for about 600W RMS per sub, proper electrical:

Enclosure Specifications:

Fb = 34.5 Hz
Vb = 3.8 ft^3

External Height = 15.5 in
External Width = 36 in
External Depth = 19 in

Port Width = 3 7/8 in

Cut Sheet List:

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

External Enclosure Parts:

Front = 31 3/8 x 14
Back = 36 x 14

Left & Right Sides:
Side 1 = 17 1/2 x 14
Side 2 = 18 1/4 x 14

Top & Bottom = 36 x 19

L Port Internal Assembly Parts:

Front to Back = 13 5/8 x 14
Extension = 5 1/4 x 14

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 car need to fit in their way in not just have the right dimensions.

- The port needs 3 5/8" of free airspace in front of it for proper operation.

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