Does anyone know who made the pre-Lci premium system? I have it, I think its great! But not sure who makes it I've heard Dirac, some company called Leer, Alpine... the amp in the trunk is branded Harmon Becker.
The first link in post #2 is pre-lci. Not sure of second link.

A picture of the headunit labeled "Alpine" was posted couple of years ago, but the amps are labeled "Harman". Harman International owns Becker, Harman Kardon, AKG, Crown, JBL, Infinity and other audio companies. Although BMW did not label the premium sound "Logic 7" in US which is a Harman proprietary DSP, i believe in fact that it is. Dirac is the premium sound not in US cars and is DSP/equalization software. I don't know if they are hardware.
