How much is the tunning for this box?
2.28 cu. ft. total
Port volume: 0.39 cu. ft.
Dimensions: 24" W x 15" D x 14.5" H

And is SUBZONE better than Q-Logic in enclosures??? oh and something else...
I have a Rockford 12" T2SUBWOOFER 2000W peak... are this dimensions good... or do I need a bigger box???

Is that before or after port displacement?

Also keep in mind that the calculated tuning frequency will vary slightly due to sub displacement.

Way to high lol.

What are the port dimmensions??? That box is to small. You will need anywhere between 1.75 and 2.5 cubic feet. And 30 square inches of port area.

I recommend you spend the money and have a shop build you a box. That is an insanely loud sub and needs the proper box. A pre-fab will not cut it.

Sub zone is the better of the 2.

But I would still have a shop build it. They will custom build it to your vehicle...

And with the sub zone optimal port area will not be factored in;)
