Personally the only issue I've ran across with the Excursions was a power issue when the car would start. There was an issue after the glow plugs warmed up and the turn of the key causing the radio to postpone its power cycle. "Sound" is something that is entirely different and something I'll need much more information on to throw a dart at some possibilities.
This short list should provide me some better insight into your situation. Thanks for allowing me the opportunity to help you out, here on the Best Buy forums, and I'm hoping to hear back from you soon!
