Thanks for sharing the settings. I just bought a CPO '07 E90 and they sound great. One question about speaker distortion. Every now and then I hear some cracking coming from the front tweeters. Since it's a CPO, I'm wondering if they need to be replaced. I don't notice it all of the time, really just with a few songs.
Is that normal, or would you have them checked out? I don't really want to deal with a dealer visit unless I know there is an issue. Any suggestions on how to confirm the distortion on my own?
