Power? Elect to support power?

Car?

What you want to archive?

At 24" deep how far is that from rear wall?

Box building skills

Can that box go in the car hole on thoes specs

Vehicle is a 2008 Jeep commander....

Running a pair of hifonics brz2100.1's strapped.

Electrical is a Singer 275a alternator, d3400 up front and a d3100 in the rear.

@ 24" deep there is still 4-6 inches space to the rear hatch door.

with the dimensions given the box will slide right in through the rear.

Not chasing #'s just want loud to the ear if that makes sense.

Decent box building skills.

Do some research and build your own. I know myself I change enclosures more than my underwear. It's only going to benefit you in the future, if you can design and build them on your own.

I think he is planning on building his own just needs some more help with the design aspect. He might not want to change boxes like he does underwear, lol. box design IMO is an art with almost infinite variables where every little thing can change a lot. I am similar to what the dude described about himself and setup above and i left the design to someone who understands it more as well.

I have built a few boxes in my time but just looking for design from someone else that had more experience than I do. I would obviously build it myself. Just looking for help is all....

If you have an android phone, get the app called "box tuning calculator" almost as good as torres and its on ur phone. Now, dc suggests 3.5cbft for each sub, so when you go on the app, make the dimensions so the box is a couple cbft high than 7cbft play with the port dimensions because the port will displace around 1.5-2cbft plus youll have bracing, also it'll give you a suggested port area range (shoot for the higher number). Also, shoot for around 14sq inches of port per foot, and make sure you add displacements and make sure that the box 7cbft NET not gross.

Here is a suggestion:

Enclosure Specifications:

Fb = 34.5 Hz
Vb = 7 ft^3

External Height = 22 in
External Width = 40 in
External Depth = 24 in

Port Width = 21 in
Port Height = 6 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) = 40 x 24

Left & Right Sides = 22 1/2 x 19 3/4

Front & Back = 40 x 19 3/4

L Port Internal Assembly Parts:

Front to Back = 16 1/2 x 22 1/2
Extension = 5 x 22 1/2

Port Left Side Assembly:
16 1/2 x 6
11 3/4 x 6
Port Right Side Assembly:
16 1/2 x 6
11 3/4 x 6

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 6" of free airspace in front of it for proper operation.

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

Thank you. I like the design alot. Just what I was looking for. Highly appreciated.

What size dowell rods are implied for bracing?

[Joe X]

2x4s for the side panels 1 1/2" wooden dowel rods for the cross braces AND the port brace which you can do with 3/4" wood.

I wanted to say again that you must be certain that you have at least 6" of free airspace in front of the port or it won't work properly, make careful measurements, if the box need a small correction just let me know.
