Wiring

Radios
The radios are of the 'wide front' type and are available in two main versions:
- a single-disc CD player (SC-805, 816 or 836 depending on market)
- a CD player with a 3-disc magazine (SC-900 or 930 depending on market)

Amplifier
The amplifier is mounted on a bracket in the boot.
The amplifier is available in two versions:
- 4*60 W (to match SC-8XX)
- 4*100 W (to match SC-9XX)

Antennas
The C70 is provided with two antennas as standard equipment, a main (power-operated ) antenna and a sub-antenna. The sub-antenna is mounted in the rear bumper on the right-hand side and is provided with a signal booster mounted in the boot under the right-hand rear light.
On cars with RTI, the sub-antenna is used by the TMC/FM receiver for RTI. The sub-antenna has no function in cars without RTI and with an SC-8XX radio. Both antennas are connected to the radio in cars without RTI and with an SC-9XX radio.
The SC-9XX radio features a diversity (two-antenna) system. The radio signal reaching the receiver is passed through a multipath detector which modulates it to an intermediate frequency. The detector senses if the signal is affected by interference and, if reception with the main antenna is poor, transmits a control signal instructing the system to switch to the sub-antenna. This enables the radio to deal more efficiently with multipath interference.

Loudspeakers
1" treble speaker in dashboard
8" bass speaker and 4" mid-range speaker in each door The signal to the speakers is balanced by means of a balance filter mounted in the door.
8" bass speaker and 1" treble speaker in parcel shelf.

Centre speaker and Dolby unit (Dolby ProLogic Surround Sound system)
Only the SC-9XX radio is suitable for this system. Note! Cannot be combined with RTI. The centre speaker unit consists of a 4" bass speaker and a 1" treble speaker.
The Dolby unit divides the normal stereo sound into several channels.

Six-disc CD changer
Standard/option/accessory depending on market.
The CD changer is mounted in the boot on the same bracket as the amplifier.
