Hey so I just built a sealed box for my new jl 12w6v2 and I was going by jl's site for box dimensions. Somehow the dimensions got off and the box is about .15 to.2 cubic feet too big. It's about 1.52 cubic feet or so before the sub goes in and it should have been about 1.34 cubic feet before the sub. So I thnk the box sounds pretty good but I'm wondering if I should add some material to deaden the sound inside to make the sound cleaner or anything else?
I'm hesitant to put polyfill in cause it seems like it isn't good if the enclosure is already above the recommended size...anyway I would appreciate some help.
Thanks!

I think you are fine.
Most subs like a bit larger sealed box anyway.

If you really want to get the most out of that sub I recommend having one of the Box Builders here (Pro-Rabbit) design a ported box for you that you can build.

A larger sealed box should be fine. Go to Walmart and buy a $5 bag of polyfill throw it in and see if you like it or not. I have always used polyfill in my sealed enclosures. Add a little at a time and test it each time to see what its doing/if you like it. Save the receipt, worst case scenario, you will have to go back and return it.

Okay well I'll try that...another thing: I can feel air coming out of the speaker terminal and there's a rattling on the speaker terminal. Not sure how it affects anything but the rattling is mildly annoying. This was my first box and I'm thinkning about building a second and maybe I will use a speaker terminal from online instead of radioshack...
