I have a Sony CD w/wireless remote 4 6x9's, 2 tweeters in the dash and 2 12" Subs all are Audiobahn. Its powered by a huge fan cooled Audiobahn amp. It has a real good sound and the subs hit really hard, they dont drown out everything else though. My subs are made out of aluminum instead of paper. I've been out of touch with the stereo world for about four years and this new stereo shop in town sold me on this stuff and I really like it.
