Get the sound of a Ferrari

I bought a Sound Racer V12.
This is the sound of the engine becomes V12 engine.

Sound Racer V12 is sensitive to noise of the alternator. It know the rpm from the noise.
And to generate the engine sound, and sends it to the audio.
Method to send the sound is either FM transmitter or AUX terminal.
Powerful sound! But immediately tired likely!

By the way where it was gonna to light trucks of our family, problems occur.

Audio attached to this car,
Clarion
AM radio only
It comes out sound from itself

Sound generating disabled.
It abandoned because it is difficult to install audio and speakers to this car.
