Well, I'm adding 2 more DP21"s to my Expedition in a month or two. I was planning on doing a clam wall at the B-pillars. But I also started thinking doing a diamond type enclosure would be pretty sweet too.

So I'm looking for some opinions on what you think would be louder, first and foremost, and look better. Which ever design I go with will be at the B-pillars, between 35 and 40 cubes, tuned to 32hz. Please explain why you voted the way you did.

I have never done either of these designs, so any tips are also appreciated.

The subs.

I like the clam idea, seems a little easier to build.

^ x2

And to add, this is gonna be one hell of a build

Should be a fun one.

Yep. Have had them for a few months now.

By the way, this is gonna just be a demo vehicle. Not looking to compete too much. Will be tuned to between 30 and 32 hz.

will be moving some air, huh!
