I recently picked up a 2008 a4 with symphony 2+ and bose. I was excited to get a car that had bose, until I listened to it. I drove this car 800 miles from Alabama to DC, and it was torture listening to this system. For reference, I am not a super-picky audiophile. I was very happy with the stock system in my mk5 GTI. That system blows this bose system out of the water. The sound is muddy, there are no highs, and no lows. I can't believe how bad it is. It is so bad, I honestly wonder if there is some problem with my system...like maybe ALL the tweeters are broken. But the mids that come out of the drivers in the door are also flat and ambiguous. The bass is anemic, and appears in some songs in unequal measure. It is mind mindbogglingly terrible.

I am planning on getting a new head unit, and I wonder if that will sort some of this out. I am curious what any of you have done (on the cheap) to brighten up this system. I'm not going to keep this car long enough to justify gutting and replacing the entire system, but any suggestion that improves it would be GREATLY appreciated.
