Recently purchased a 2011 Prius III with the JBL Premium Sound w/NAV. I've turned the Treble/Mid's/Base all the way up, and find it sounds best overall when the speakers are "centered", BUT.... 95% of the sound is in front of the car, so it doesn't sound centered. I though perhaps the rear speakers weren't working, so I moved the settings to the back, and you can hear the speakers, but they sound isn't impressive at all.... basically useless IMO. Is the way of the JBL Premium Sound system, or is there something wrong? Any advice/help would be appreciated! Thanks! Jeff
I upgraded front speaker to 6 by 9 3 way speaker and got the best result. Posted via the PriusChat mobile app.
