I was in the hospital for a couple of days and was just released today.
Yes, BMW OE speakers are 2 ohms and the Focal are 4 ohms.
The OE BMW amp is powerful enough to drive a 4 ohm speaker without any problem and there is no noticeable mismatch on speaker output either.
So in summary yes, the Focal is a very good replacement for the stock center channel speaker and the BMW amp has enough power to drive it.
Thanks Dan, hope you are well and stay that way!!!
It is funny how the revival of this thread spurs new interest in this upgrade. I posted my change to focal on my home board for the 6 Series and had 6 people who wanted my spare speaker, ended up putting some folks together who bought a pair to split. Anyway, your DIY's always are relevant no matter how old they are.
To the guys who are considering this, search out Dan's (whatheheck) post on changing the tweeters over to Polk Audio. That to me was a GREAT upgrade, even more noticeable than the Focal center channel.
First of all thank you Dan for posting this thread and thank you Mark for reviving it. I did this mod today and I am very happy with the sound in the beast with the Focal. I even had luck that in the music shop they couldn't find the second speaker so they charged me only for one -
That was only 33 Euro :1:
So thanks guys and all the best :byee55amg
Thanks for the secondary shout-out, Dan really deserves all the credit.
That is great news about the single speaker purchase, the cool thing about this mod is that eventually someone will want the orphan speaker. Make sure you check out Dan's write-up on the Tweeter replacment in the door corners...another GREAT audio mod that is simple but effective. By the way, some guys on the 6 board have replaced the tweeters with the Polk Audio (db1001 which I did, this is the newest unit), and did not remove the door panel to change the crossover. They are still pleased with the easier/quicker replacement.
This works with the M5 as well, with one slight modification. The grill has to modified slightly to accommodate the height of the speaker or else one corner will pop out of the retaining holes. The M5 grill is rectangular and is slightly bent. However, under the grill there is a foam pad and a plastic lattice for stability. I just simply snipped out part of the plastic lattice to accommodate the extra height and it fits like a glove now. I've attached a picture of it. Also my OEM speaker was slightly different I because I have the DIRAC system. There is still a very noticeable difference in clarity and overall sound quality though. Thanks Dan! Now for the tweeters! I'll probably post some comments in the E60 section and direct them to this link. Thanks again!

Great upgrade, I was really impressed with the sound quality from the stereo in Dave's M5, am wondering if an upgraded center speaker made the difference. My M6's audio quality is good but not great--this is now on my list.

I decided to go ahead and bite the bullet and install a set of Focal K2 Power 100KRS in the front doors. It's Focal's component 4 inch slim line tweeters and woofers. If fit perfectly in my M5 due to the fact that I have the DIRAC audio system, which use 4 inch speakers in the front and back door panels. Even though DIRAC is a great system, mainly because of the DSP amp, the speakers are still a little weak. The 100KRS work well with the Focal Access 100CA1, and the amp is powerful enough to make good use of them. I highly recommend these speakers.

So you have changed the High-end DIRAC LPG speakers with Neodymium magnetic for FOCAL speaker? Strange thought :3:
It's same if I would change my TAD HI-FI speaker for some Focal :1:
