Bimmer Tech Alpha One Speaker & Amp Upgrade
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.

I can't find upgraded subs for the i3 but I'm going to buy the amp, if you know of someone selling upgraded subs let me know, but I'm not going to go as far to remove door panels for the other speakers.
