Remote Control Interface Unit

The power amplifier (C0491) receives inputs from the head unit (C0092) and relays them to the speakers as follows:

NOTE: The LH and RH speakers share the same connector numbers as they utilise the same door harness.

A positive signal is provided by the power amplifier to the RH front mid-range speaker (C0369) on an OK wire. The RH front mid-range speaker (C0369) is provided a negative signal by the power amplifier (C0491) on an OB wire. A positive signal is provided by the power amplifier to the RH front high range speaker (C0680) on an OK wire. The RH front high range speaker (C0680) is provided a negative signal by the power amplifier (C0491) on an OB wire. A positive signal is provided by the power amplifier to the LH front mid-range speaker (C0369) on a YK then OK wire. The LH front mid-range speaker (C0369) is provided a negative signal by the power amplifier (C0491) on a YB then OB wire. A positive signal is provided by the power amplifier to the LH front high range speaker (C0680) on a YK then OK wire. The LH front high range speaker (C0680) is provided a negative signal by the power amplifier (C0491) on an YB then OB wire. A positive signal is provided by the power amplifier to the RH rear mid-range speaker (C1577) on a UK wire. The RH rear mid-range speaker (C1577) is provided a negative signal by the power amplifier (C0491) on a UB wire. A positive signal is provided by the power amplifier to the RH rear high range speaker (C0679) on a UK wire. The RH rear high range speaker (C0679) is provided a negative signal by the power amplifier (C0491) on a UB wire. A positive signal is provided by the power amplifier to the LH rear mid-range speaker (C1577) on an SK then UK wire. The LH rear mid-range speaker (C1577) is provided a negative signal by the power amplifier (C0491) on an SB then UB wire. A positive signal is provided by the power amplifier to the LH rear high range speaker (C0679) on an SK then UK wire. The LH rear high range speaker (C0679) is provided a negative signal by the power amplifier (C0491) on an SB then UB wire.

NOTE: It is essential that all speakers are connected correctly. A speaker connected incorrectly will be out of phase with the remaining speakers, causing a deterioration of sound quality.

Remote Control Interface Unit

The remote control interface unit (C1897) is provided an ignition feed via fuse 11 of the passenger compartment fuse box (C0580) on an LGW wire. The interface unit enables the head unit to communicate with the remote audio controls, and is earthed on a B wire.
