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.
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.

I forgot to mention I tried the fields also. I'm trying to get the rear speakers to be louder. They are significantly quieter than the front on the same volume level.
Hmm... I did see somewhere some info where you hold down two buttons while powering on the radio and it lets you into the 'tech' mode. It plays static in all speakers one at a time to test each one, etc. I would post a Q in this forum. Ford techs hang there.
Speaker Walk-Around Test:
NOTE: To enter the speaker walk-around test or audio unit self-diagnostic mode, the audio unit must be turned on and in radio tuner mode (AM/FM).
1. To enter the speaker walk-around test, simultaneously press and hold the audio unit preset buttons 3 and 6 for approximately 3 seconds, then release.
2. The speaker walk-around test applies sound to each speaker for about 1.5 seconds. Each speaker is tested and displayed on the audio unit in the following sequence: RF, LF, LR, RR.
Audio Unit Self-Diagnostic Mode:
NOTE: Always document and clear DTCs and carry out the audio unit on-demand self-test again.
1. To enter the following tests, press the desired preset button while in the speaker walk-around test or while in the audio unit self-diagnostic mode.
2. To exit the audio unit self-diagnostic mode, turn the key or the audio unit to OFF.
3. The audio unit self-diagnostic mode has 5 tests available:
Preset Button 1 = Audio internal/external SELF TEST. This test is an on-demand self-test. If SELF FAIL is displayed, press TUNE > to scroll through the DTCs stored. Refer to the Audio Unit DTC Index. If the system is OK, SELF PASS will be displayed.
Preset Button 2 = View/Clear continuous DTCs. NO DTCS is displayed if no DTCs are retrieved. If DTCS FOUND is displayed, press TUNE > to view the DTCs retrieved. Refer to the Audio Unit Diagnostic Trouble Code (DTC) Index. To clear all DTCs, press the EJECT button. DTCS CLEAR will be displayed.
Preset Button 3 = SIGNAL TEST. This test measures the average strength at the current tuner setting. ** Perfect for testing antenna types and position changes. **
Preset Button 4 = Software level query. This test queries each audio system controller for its software configuration level. SOFT LEVELS will be displayed upon completion of the query. Press TUNE > to scroll view the software configuration version level.
Preset Button 5 = DISPLAY TEST. This test will light all the audio unit display segments for 5 seconds. When the test is complete, DISPLAY TEST is displayed on the bezel.
5. To exit the self-diagnostic mode, press the power button on the audio unit or turn the key to the OFF position.

Thanks for the information. My sound system sounds really good, So I think I won't mess with mine as if it can be made to sound worse. I am sure I could do it.

Thanks for the information. I will see what can do with it. If not I will post like you said.
There is some interesting info in that post, do you have the breakdown for all the wire colors out of the factory head unit as well. I want to keep my facgtory sirius radio, but I want to add an amp to run my aura base shakers, so it doesn't have to be top of the line sound quality, just the signal. So I bought a speaker level to RCA converter, just need to know what wires to splice...
