Box Design Needed

[Brayden76]

Can anybody design me an enclosure for 2 Sundown Sa 12s? I would like a sub up and port in the middle and back design. Ive tried multiple programs and its not working for me. I have about 34w and length and height don't matter. Im looking to run about 2000w at 1 ohm to the pair.

So here is a suggestion, power: to subs rated, amp subsonic filter to 28Hz, minimum port clearance 4 3/4", figure is just an assembly guide:

NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside.

Could I use that same box but mount the subs in the top piece?

[Joe X]

Yes, just don't do it if you are installing this in a trunk car.

So each front piece needs to be 15.125 inches?

[Brayden76]

And the back port wall looks longer then 11/16

I have modified a cutsheet to match the figure, sorry.

[Brayden76]

Thanks I appreciate it a lot

So the inner port wall is only 9/16 long?

The extensions are very small as you say, being so short you could dismiss them without any significant changes in performance.
