On my 2003 M3 CSL SMG next to the tire pressure buttons and the others there is a button with a little speaker on it....in the manual it says something about the speaker system...when i activate it the sound is much better!!!

I was wondering why in the heck is this not always active?

Thanks for any help...

i'm pretty sure its for the optional HK system, i guess when bmw made the system optional they gave you an option to turn it on...

It is the subwoofer switch for the Harmon Kardon sysytem.

It isn't...

This button activates the HK "Spatializer" signal processing that changes the sound stage of the audio system; instead of sounding like is coming from the fixed speaker locations of the car, this processing takes the sound and "move" it to the center of the car, creating this "space" between the listener and the source.

M3Tech is correct. The button is NOT for the sub-woofer

Beat me to it... darn....

If you have a decent ear, you can really tell a huge difference between the two!! Take a piece of music (classical works best, something with a sort of soft drone and a nice beat to it will work too - techno) and play around with the button... you can tell it sounds more "complete" and "around you" when it's on, rather than when it's off....
