DESCRIPTION - RADIO - Fiat GRANDE PUNTO 1.2 8v

As an option, the vehicle may be fitted with a HIFI system with special hifi speakers and a subwoofer containing a power amplifier.The system has been developed ad hoc for the vehicle: the acoustic properties of the passenger compartment have been carefully studied so that the amplifier and the speakers are ideally suited to the vehicle: optimum listening is available in any part of the passenger compartment.Unlike the system fitted as standard, the Bose system offers:- special speakers at front and rear;- subwoofer containing a power amplifier located in the boot.767A single channel audio power amplifier is located inside the subwoofer box for the operation of the actual subwoofer; a protective fuse also protects the amplifier power supply.The other components (radio, aerial, etc.) are the same as the standard system.For more details
