Wow.. Mine doesn't sound like that at all. No mids scooped, not boomy or flabby bass. If my EQ is set flat its a pretty perfect even tonality across the range. Are you using a MyLink EQ setting or a custom EQ? Sounds like something isn't right to me. I went from having 3 sets of JBL 660Gti's and 2 JBL W15GTi's sealed and a JBL MS8 with proper amps... Even though no system will sound as good as that car from a factory setup perspective ( I won Iasca world finals in SQ 2012 in that car ) I was not disappointed at all with the way it sounds. I feel like something isn't right with your setup.
