Kicker Comp R 12s box build help?

[Connor]

Could anoyone help me with designing a ported (square/rectangular port, not a round port) sub box for 2 12" Kicker Comp R's (Dual 4 ohm)? Preferably with the port in the center of the box, and the subs to each side of it.

And what would be your recommendation for what to tune the box to?

Welcome, no problem, post your vehicle and amp models and max dims for the box, also you mean CVRs right?

Seems iffy to me...

I'll measure in the morning, I'm just setting it on top of the back seat of a 2004 Dodge Ram quad cab. I'm using a Hifonics Brutus 2400 watt amp (BRZ2400.1D). And they're not CVRs, the CompR is in the newest model out. http://www.sonicelectronix.com/item_66619_Kicker-CWR124-40CWR124.html

Max dimensions are 36" long x 20" wide x 24" tall. Thanks

Those are not, by any means, the dimensions needed, they're just simply the MAX. I'm pretty sure the box doesn't need to be 10ft^3. Anything within those dimensions will work.

Ok here is a suggestion, bear in mind that those backseat enclosures don't give best results, also upgrade your electrical and set your gains properly:

Enclosure Specifications:

Fb = 33.8 Hz
Vb = 4 ft^3

External Height = 18.5 in
External Width = 36.25 in
External Depth = 18.5 in

Port Width = 3 3/4 in

Cut Sheet List:

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

External Enclosure Parts:

2x Front = 16 1/4 x 17
2x Front Internal = 14 3/4 x 17
Back = 36 1/4 x 17

Left & Right Sides: 17 x 17

Top & Bottom = 36 1/4 x 18 1/2

Shared Port Internal Assembly Parts:

2 x Front to Back = 15 1/8 x 17
2 x Extension = 9 9/16 x 17

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.

- The port needs 3 3/4" of free airspace in front of it for proper operation.

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

Thanks!

Hi, i have the same question.

I have 2 comp Rs (2 Ohms)

I drive a 1999 Chrysler Sebring

Max dims. :32W 17.5D 16H

Amp: Kicker DX 1000.1 (might upgrade to Kicker 40KX1600.1) <--will that change anything?

Only like this:

Enclosure Specifications:

Fb = 33.8 Hz
Vb = 4 ft^3

External Height = 17.5 in
External Width = 32 in
External Depth = 21.25 in

Port Width = 3 3/4 in

Cut Sheet List:

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

External Enclosure Parts:

2x Front = 14 1/8 x 16
2x Front Internal = 12 5/8 x 16
Back = 32 x 16

Left & Right Sides: 19 3/4 x 16

Top & Bottom = 32 x 21 1/4

Shared Port Internal Assembly Parts:

2 x Front to Back = 17 7/8 x 16
2 x Extension = 4 13/16 x 16

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

- The port needs 3 3/4" of free airspace in front of it for proper operation.

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