Re: 15" brama vs two 10" Alpine Type R's
I'd have to disagree with the subzero box altogether. If you had a shop port the box for you, it wouldn't be big enough for the brahma. If you can't build your own box, your best bet would be to cancel the order for the subzero, and head over to http://www.gnomeaudio.com (LoneRanger here on the forums). You won't be spending over $200 shipped for a custom box from him, and it'll be built like a tank.
