As factory systems go, this is one of the better ones I've had. I used to work in Car Stereo business and while this isn't as good as $10k system, it's pretty darn good. It's better balanced than most systems I've used and I find the stock (centered) locations on the EQ work pretty well. Normally I'd have to boost the highs and lows a little but they've obviously used some type of EQ when they set these up. Could it use a little more THUMP? Sure, but mostly in the mid bass area. It handles deep bass pretty we'll and the highs are pristine and clear while not being too harsh.
If I were going to make any change (which I'm not) it would probably be to do something to increase the mid bass like the poster did above. Otherwise, I think it's pretty darn good for a factory installed system and the Bass is certainly good enough on it's own. I just wish it blended a bit better with the Mids in the front.
