If your replace just the speakers you're going to be disappointed. The BMW amp has built in crossovers so you have no easy access to a full range signal to drive a good set of coaxes or three-ways. Even if you go with a good component set (MB Quart, Eclipse, Alpine, a/d/s, etc) the BMW amp's crossover points won't be ideal.
If you want to replace your speakers, you ought to consider replacing the factory amp too.
