It has begun! I saw the amps (1 ZERO1 and 2 ZERO4), the speakers and the BattMobile batteries today when I dropped off the car. The Mosconi ZERO1 is huge!!! By the way, I am replacing the factory battery with a BattMobile battery and I'm also putting two extra ones in the trunk. They are small and light. I can't wait to pick up my car in two weeks. I am confident it will be one of the best sounding Teslas out there.
