A couple of box designs which one to choose.

This box is for a dd9515 and will be in a Chevy Cobalt coupe on 2000 watts.

Each box has the same outside dimensions(32x16.5x22), tuning(36.5hz), and cubic feet(4.15)

I am going by DD's box specs for the tuning and airspace.

Box#1: 67.5sqin port, Double Baffled, and some bracing

Box#2: 75sqin port, no DB, no bracing

I cannot go any bigger on the outside dimensions.

What do you guys think?

Do box #1, without a double baffle and more port area or airspace.
