Well, I'm stuck in Mod w/ my ext silverado...so I figured, why not try an semi-permanent wall.

I messed around w/ a few ideas, and came up w/ a drawing for a 2x4 skeleton that will fit through the doors. (not 3rd door)

I can get a solid 16-16.25cuft (gross) out of my first design w/ a 2.25" baffle and a single layer of 3/4" on the skeleton. But, here is the kicker...the internal depth of the wall is only 15".

I have never built a wall before, so I don't know how bad that will hurt airflow or maybe choke the port.

As of now, I have 2 DD3515's doing just 153's w/ 2 20.1's in basically a daily box (subs and port up). I was thinking start w/ them and maybe go to a 3rd 15"...but 55-56' is really all I'm looking for.

So, how does ~14cuft w/ ~330-360sqin port ~7" deep. The port would be around 10-10.5" wide, but only 10.5-11" from the back wall of the box.

Distance from the baffle to the front glass will be ~50". From top of port (extreme top left) ~80" to the kick. And from center of baffle between the subs to the kick (~10" from the right wall of box) is ~56".

Am I psychotic, or would this be a decent design to start with?

The only way to know is build and test. Nice drawing. What did you use?

I used Google SketchUp.

Anyone else wanna chime in please?
I have the skeleton up and going, hope to have it boxed in by Sunday.

What do you think about this design?
Am I wasting my time?

Looks like a good design, worth a try and build. The depth won't hurt you to much on 2 subs. If you went with more, then there may be a prob with back pressure at that depth.

The port is fine for being that far away from the back wall.

Nice drawing by the way. I like sketchup as well.

This is for spl of daily?

To tell the truth, I'm just having alil fun w/ something new.
The wall will fit through the doors, so it is FAR from permanent.

This truck is my daily driver, so I will most likely build some blockers to fill in the port area some for daily driving.

Its nowhere near a true Mod build.
Just something louder than I used to be.

Sadly, my old 153.1 was by far the loudest in the Monroe, La area. It sounded pretty good though. It would play any song and peaked at 45-47hz.

None of the other local shops build for even local SPL anymore. I have been the only thing keeping it alive for the last few years Sad

As a matter of fact about 2years ago, I held the first SPL comp Monroe/West Monroe had seen in over 6 years.

I am trying to bring it back and get locals interested, but its slow going. Even other installers at local shops will not compete at my local shows. Its sad. I would love to have some friendly rivalries spring up Smile

(all in good fun, ya know)

At least USACi will be in town for Dream Cruz this summer.

Well, I got the skeleton about done today. Still going to add more 2x4's. After getting to the point I amp now, I have 4 studs left...plenty for extra braces.

I'll get some pics up soon.

Here is the start of the skeleton:

Pretty basic, but should be the job done.
