I'll definitely be interested to hear how that turns out. That's not normal at all. My Bose system in my Cruze sounds good too for this class of car. It doesn't have thundering bass by any means, but it does have good clarity and sound. It definitely does not have an echo or 'reverb' sound to it at all in mine. Is this all audio sources that you're getting this same type of sound? Or is it only some sources? If it's through your cell phone, your phone could possibly have some sound effects or DSP turned on. Just an idea. When you say Tech's say it sounds great, I'm wondering if they're listening to it on a difference source than you usually do.
