On the sound and making them louder - why? I hear that you want them to sound more exciting, but to generate the sound artificially? What's the point of that? Why not just put MP3 players, amps and speakers on the things? If that's the sound the car makes, then that's the sound it makes. Everything in F1 is becoming artificial.
Next thing F1 cars will have 6x9s and fancy mag wheels.
