could someone please spare 5 mins to look at these figures :)

[TUNES]

boot area is maximum

width 39.5"

height 20"

depth top 31.5

depth bottom 39.5"

[Joe X]

Ok, here is a suggestion for 4 of those, it can be changed if necessary:

Enclosure Specifications:

Fb = 32 Hz
Vb = 7.8 ft^3

External Height = 18 in
External Width = 39.5 in
External Depth = 30 in

Port Width = 28 in
Port Height = 3 1/2 in

Cut Sheet List:

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

External Enclosure Parts:

2 x Top & Bottom (3 parts) = 39 1/2 x 30

Left & Right Sides = 28 1/2 x 15 3/4

Front & Back = 39 1/2 x 15 3/4

L Port Internal Assembly Parts:

Front to Back = 22 3/8 x 29 1/2

Port Left Side Assembly:
22 3/8 x 3 1/2
Port Right Side Assembly:
22 3/8 x 3 1/2

Assembly guide (generic dimensions):

Important notes:

- All boxes built outside the vehicle 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 subsonic filter to 28Hz is suggested.

- Top to bottom brace is 1 1/4 wooden dowel rod, port brace is just 3/4" MDF as the rest of the box.

hey joe that looks awesome but what if i asked if it could be 39.5 wide and 19 high? depth can be whatever it needs to be

[Joe X]

Changed to 39.5", however if I make it taller it would need loose depth to stay the same volume. I need the depth for port clearance to the backwall.

[TUNES]

thats ok buddy, could i put the box on 1" raisers so would allow cables to run underneath?

[Joe X]

Yes,why not, just very solid support.

[TUNES]

Hey joe sorry not been on, been loaded down with work. Ive imported a circle jig from the states and waiting for that to turn up so I can build that box nice and properly. Would it make a difference if I countersink the subs?

[Joe X]

No problem, unless you were to use higher power subs later, flush mounted subs are a little harder to remove though.

[TUNES]

hey buddy hope you good, i been so busy and ill that ive only now started looking properly at starting your box design

when i calculated the dimensions, it comes out at 12.34cuft? and i need about 7.5-8ish or am i calculating something wrong....as usual lol

and cargo area i have to play with is 39.5" w, 20" h and 30"d

i have a sq up front and i would like the box to be for spl when i want to really bump it hard

i want to use 4 of these http://www.jbl.com/estore/jbl/us/products/GTO1214/GTO1214_JBL_US

and 2 of these http://www.jbl.com/estore/jbl/us/products/GTO14001/GTO14001_JBL_US?searchMode=refurbishedProductOnly

sorry for the long ass message but im ready to build and just wanted to double confirm original numbers were correct as it looked a massive box for 7.8cuft lol

hope to hear from you soon buddy

[Joe X]

Checked with Torres gives similar results, I can guarantee at least it's not 12.34 cubes net.
