They are a forum boner. Don't do rated power, but do enough to still make them a decent deal I guess. I've never been a personal fan of PA. Believe it or not, I like Lanzar better.........
How much do you have to spend?
And PS: Brahma's are D2 subwoofers; neither of those power options you have listed in your first post are relevant to what the Brahma can be wired into. You'd need ~700-1000w @ 1ohm and ~1500-2000w @ 2ohm. So, for two Brahma's, none of those amps are a very good choices at all as they make their most power into a 1ohm load.
