Sometime car makers go down some really bizarre dead ends. My 2009 C2S Carrera has a “Bose” made by Becker, system that plays 5.1 surround DVD A and other formats like MP3s and such. Wha? The car is a pretty noisy sports car… the sound system is really mediocre at best but 5.1 DVD A?
Anywho… I have established that the devil for this car is in the amplification… but the “amp” is a combo unit of DSP (DVD A etc…) and amplification under the seat. It connects to the big head unit in the dash via a proprietary protocol to pass all these crazy formats.
From being on the Porsche forums… I really think I am the only one who ever even knew about the DVD A capability.
I spent lots a time and money upgrading tweaking blah blah blah… it is still a crappy environment… but we soldier on.
