You want the Brahma
Excellent SQ, and if you want it to go loud. Well, Just look at the videos (check out the ford explorer... Quarters brouncing off the roof) It's not cheep, but then again, great stuff is almost never cheep.
I have the tumult, which was designed for home use (design dosn't take into account the cabin gain when it was designed.) but they have the same basic motor and design. It owns everything out there. Get a Brahma, you wont be disappointed.
