DESCRIPTION - RADIO - Alfa Romeo 159 2.4 JTD 20V Da 01/06

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

FUNCTIONAL DESCRIPTION - RADIO - Alfa Romeo 159 2.4 JTD 20V Da 01/06

Radio P20 is supplied directly (pin 4 and 2 of connector A) from the battery via the line of fuse F23 of the engine compartment junction unit B1 .Pin 8 of connector A is earthed.Pins 1 and 3 of connector A receive the CAN line by which the radio P20 is connected to the Body Computer M1 and the other system nodes.The radio P20 is connected, via the CAN, to the radio controls on the steering wheel, via the clock spring D47.The amplifier P70 receives a direct supply from the battery - at pin 31 - via the line for fuse F54 of the fuse box in the boot B45; pin 2 of amplifier P70 is earthed.Pin 6 of P70 is connected via a line to radio P20 - pin 6 of connector C - which supplies a positive signal to enable the amplifier to be switched on.The cables with signals for the speakers leave from connector B of P20; these signals are sent to the BOSE amplifier P70 which controls the actual speakers:- pins 5 and 6 of P20 to pins 7 and 19 of P70 and to the left front speakers P35 and P45 - pins 31 and 32 of P70;- pins 3 and 4 of P20 to pins 8 and 20 of P70 and to the right front speakers P36 and P46 - pins 26 and 27 of P70;- pins 7 and 8 of P20 to pins 9 and 21 of P70 and to the left rear speakers P30 and P47 - pins 4 and 16 of P70;- pins 1 and 2 of P20 to pins 10 and 22 of P70 and to the right rear speakers P31 and P48 - pins 5 and 37 of P70;The other signals leaving the BOSE amplifier P70 control the specific speakers:- centerfill P32 - pins 3 and 15 of P70;- subwoofer in the rear parcel shelf P49 - pins 11, 12 and 25 of P70; the subwoofer P49 is also supplied via the line for fuse F61 of the fuse box in the boot B45.The "ambient" microphone located in the front courtesy light G10 - connector E - is connected to pins 29 and 30 of P70.The aerial P25 is connected to the radio by means of the special coaxial cable.A connection lead runs from connector E of P20 to CD player P75:. this cable, is divided into two sections: one under the dashboard and one under the passenger compartment lining (coupling D96).
