Well, have you changed the sound field? Press menu until you come to the 'driver seat', 'all seats' or 'rear seats' display. Once here, use the arrow keys to select from one of the three. Choose all seats when you want everyone to listen, driver seat when it's just you. This adjusts 'sweet spot' of the stereo. The driver seat option makes a huge difference and that's the one I keep it on 90% of the time. Give it a try.
