What do you guys think of this design for 2 soundqubed hds300-12's. Subs up port back on a soundqubed 1200. Building for my bro in law in a 2007 yukon. I opted for a little on the big side seeing as how we are only running 1200 watts on them, he may uograde to the 2200 in the future if this isn't loud enough. He is coming from a single JL 12W0 in his challenger on maybe 300 watts so I'm sure he will like it, just want the most bass we can get.
Max dimensions are 48" wide x 16' tall x 24" deep.
