I have spent years in audio and my ML audio system sounds worse in my 2002 Es than my Premium sytsem did in my 1997 ES? What is up with that? The local dealer has no clue as to what to do. Any audiophiles out there that can give me feedback???? My daughter's Nissan sounds better and so does my wife's RX 300. Anyone have the same problem? I thought this was the best audio system they made for this car... Any ideas on what the problem could be? Very flat high end, little dymnamic range, lot's of mids, no clear separation, no real low end. Sounds better in the back seat than the front..
