Do you think the center speaker is really worth it? Was thinking to start with just the front door ones.
I'm with you on those jangly piercing highs in the stock "hi fi" system. For some reason they didn't bother me much at first, but now they really get on my nerves.
[edit]
One other question, the Focal site specifies IC BMW 100
L which seem to differ only at the bezel, where the L has a lip with a foam shroud, and the regular 100 is more flush. Which one did you choose?
