Here is a suggestion, any changes let me know, the c124s are rated only 150W so be a bit careful with the 500.1:

Enclosure Specifications:

Fb = 35 Hz
Vb = 4 ft^3

External Height = 17 in
External Width = 38.75 in
External Depth = 15.5 in

Port Width = 3 in

Cut Sheet List:

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

External Enclosure Parts:

Front = 35 x 15 1/2
Back = 38 3/4 x 15 1/2

Left & Right Sides:
Side 1 = 14 x 15 1/2
Side 2 = 14 3/4 x 15 1/2

Top & Bottom = 38 3/4 x 15 1/2

L Port Internal Assembly Parts:

Front to Back = 11 x 15 1/2
Extension = 3 x 15 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 car 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 3" of free airspace in front of it for proper operation.

- Setting your amp subsonic filter to 32 Hz is suggested.

Thank you I had one of the comps in a sealed box and it was surprising it took some power the max on the comps I have is 500 as the manual says and my amps rated power at 2 ohm is 500 so I should be ok
