Ok, so I don't get a lot of time in this car since it's my wife's, but I finally managed to find the sweet spot in the sound system tonight. I'd been having issues with what seemed to be a bad crossover setup - the speakers sounding like they were going to explode at higher volumes, having to fade the sound to the rear and turn down the bass. So I was fooling around with it tonight, turned off both the surround and the ASL, set the treble one click from max and both mid and bass two clicks from max, and suddenly I had great sound. Still not comparable to the Bose in our FX, but definitely enjoyable. I think the main culprit was the Surround setting. I'll never push that button again, at least not for straight stereo sources.
