Just curious if anyone here has upgraded their Harmon Kardon system using the "Plug n Play" Bimmer Tech Amp and Alpha One speakers? Looks very intriguing but would love some feedback from users who actually have it in their i3. I have a friend who has one of their upgrades in their 3 series and it's quite nice.
