I run MBQuart in my Passat. They are the 'Q' series, so I can't speak for the lower priced line, but these babies are amazing. Just a few weeks ago I was driving a buddy of mine to the Colts game and we were listening to a song (it escapes me which one exactly) and all of a sudden he goes, "oh THAT'S what he says right there! I never knew what he was saying in that part of the song, it's crazy how much better I can hear the lyrics through these speakers".
I think I've said it before that if MBQuart had home speakers I probably would never know that Axiom even existed, because I certainly would have bought MBQuart home speakers without thinking twice if they had carried them. Oh well, I'm not mad.
