like Deadeye said, I have a real hard time believing this . . . I do not believe that these cars have THAT crappy an alternator and/or battery that they cannot handle a half decent head unit; what about the cars that came with NAV, do they have a completely different / upgraded alternator and battery? doubt it

If you were talking about a huge system with power amps and a trunk full of subs that would be a different story
