Radio, Stereo, and Compact Disc: Description and Operation

AUDIO SYSTEM - LOW LINE

DESCRIPTION

General
The low line audio system features a centre console mounted radio/cassette player, which will operate when the ignition switch is in the 'auxiliary' position.

Five door vehicles have a mid-range speaker mounted behind each front and rear door trim casing , in addition to high range speakers mounted behind the door mirror trim casings. Four door vehicles have mid-range speakers mounted behind each front door trim casing, and both rear passenger compartment trim casings.

OPERATION

General
Feed from the positive battery terminal (C0192) is supplied to fusible link 1 and fusible link 4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) is connected to fuse 9 of the passenger compartment fuse box (C0587) by an NW wire.

Fuse 9 (C0585) provides a constant battery feed to the head unit (C0098) on a P wire. The head unit uses this feed to power its memory circuits, and is earthed (C0098) on a B wire. Fuse 9 (C0585) also provides a feed to the CD autochanger (if fitted) (C0941) on a P wire.

Fusible link 1 is connected in series with fusible link 2, which is also located in the engine compartment fuse box. Fusible link 2 (C0571) is connected to the ignition switch (C0028) by an NR wire. When the ignition switch is turned to the 'auxiliary' position, current flows across the switch (C0028) to fuse 11 of the passenger compartment fuse box (C0588) on a PS wire. Fuse 11 (C0580) provides an auxiliary ignition feed to the head unit (C0098) on an LGW wire.

AUDIO SYSTEM - MID LINE

DESCRIPTION

General
The mid line audio system features a centre console mounted radio and a front loading single CD player, which will operate when the ignition switch is in the 'auxiliary' position. Some vehicles are also fitted with a power amplifier and sub-woofer.

NOTE: The supporting circuit diagram shows the mid-range audio system fitted with optional Harmon Kardon speakers. A system fitted with standard speakers will not have a power amplifier or rear high range speakers fitted. The connector numbers applied to the high range speakers differ between the two speaker systems.

OPERATION

General
Feed from the positive battery terminal (C0192) is supplied to fusible link 1 and fusible link 4 of the engine compartment fuse box (C0632) on an R wire. Fusible link 4 (C0574) is connected to fuse 9 of the passenger compartment fuse box (C0587) by an NW wire. Fuse 9 (C0585) provides a constant battery feed to the head unit (C0921) on a P wire (P then PK if fitted with a power amplifier) and the power amplifier (C0491) on a P then PK wire.

Fusible link 1 is connected in series with fusible link 2, which is also located in the engine compartment fuse box. Fusible link 2 (C0571) is connected to the ignition switch (C0028) by an NR wire. When the ignition switch is turned to the 'auxiliary' position, current flows across the switch (C0028) to fuse 11 of the passenger compartment fuse box (C0588) on a PS wire. Fuse 11 (C0580) provides an auxiliary ignition feed to the head unit (C0921) on an LGW wire.

The head unit (C0921) and the power amplifier (C0491) are both earthed on B wires.
