A sophisticated Bose HIFI system with special HIFI speakers and an outside amplifier is available on request.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, which are midwoofers with separate tweeters;- subwoofer rear speaker located under the rear parcel shelf;- centerfill speaker located in the centre of the dashboard under the centre air vent;- high power amplifier located under the rear parcel shelf in the boot.The system is completed by a microphone, located in the centre courtesy light, which detects background noise in the passenger compartment: the signal is sent for amplification allowing the optimum adjustment and equalizing of the output levels.The other components (radio, aerial, etc.) are the same as the standard system.For more details See descriptions 5570 ACCESSORIES
