My stepmother owns a 200 or 2001 328. IMO, the stock setup is atrocious. The bass is very weak and muddled, the highs are not very crisp, and they distort far to easily.
Sorry to say, but I'm afraid it is garbage.
Then again, she likes it just fine and thinks I'm crazy for investing almost $2000 in sound equipment.
