Car Enthusiast

Hi all from Italy,
my name is Carlo. I live in a small town near Venice (50km's). I have just purchased a new car (Fiat Tipo 2015) and need some advice for the new system. There will be a lot of components involved: 3 DSP's, 8 Amplifiers, 20 speakers. Maybe I will use an Arduino as remote controller for the DSP's.
So, here we are. I'll post the system configuration in the next 2 hours.

And... thanks for the help!
