Newbie Bernard here, Fascinated by the subject but definitely not an expert on car audio. I do know what sounds terrible though! I also feel that what one listens to has a lot to do with what is an appropriate system right? I'm probably sooo stating the obvious! My favorite car stereo was a stock system in my old Pathfinder. Call me a fool. Then again, I like classic rock, oldies, jazz etc. I don't need insane bass frequencies. Looking forward to being part of the discussion. B
