I recently bought by wife a 2007 EL. While on a road trip a few weeks back my sister inlaw stated she couldn't hear the stereo very well. My wife and I never noticed but the rear speakers didn't put out as much sound as the front when balanced out. I started playing with the fade and noticed that the rear speakers indeed do not put out as much sound when I fade all the way back as the front do when I fade all the way to the front. So we took it in to the dealer and supposedly there are special features and adjustments not listed in the manual that needed adjustment. Well the stereo does sound slightly better but still not perfect. I was wondering if anyone had a list of these "secret" adjustments and how to acess them. This doesn't sound to far fetched to me because the volvo my wife had previously, had similar adjustments with a seperate manual that I found online. Thanks for any help.
