Amplifier bypass cable specially designed for Range Rover Sport and Discovery III cars fitted with a factory Harman/Kardon amplifier (Usually located under the drivers seat)
This amplifier bypass cable is designed to bypass the original amplifier to allow the installation of a new car stereo head unit in vehicles that have fibre optic Harman/Kardon amplifiers. The cable bypasses the amplifier and connects audio from the head unit to the 4 main speakers in the car.
Retaining the original Harman/ Kardon subwoofer
To retain the original subwoofer in the vehicle we do offer a dedicated sub amplifier fitting kit (
AK-LR-01)
This new amplifier is installed when using an amplifier bypass cable. The original amplifier has to be kept in place for the MOST fibre optics and rear seat entertainment system to still work, however you have to disconnect the Green speaker side of the amplifier outputs and connect this to the new head-unit.
This kit has a T harness allowing you to keep the original power supply to the OEM amplifier but also provide power to the new Monoblock amplifier. The phono lead is to connect the new head-unit to the amplifier. The cars sub-woofer wires (marked on the wire harness) are connected to the new amplifier outputs
Installation notes (Included in instructions)
Disconnect the green and grey connectors at the amplifier, the amplifier is located under the driver’s seat (right hand drive). Connect the 20-308 to the connectors in the car. Run the cable up to the dashboard and connect the ISO connectors to the new head unit. An ignition power supply will need to be connected (red wire) we recommend using the power from the cigar lighter or a power feed from the fuse box. The pink and blue wires can be used for the original sub woofers and tweeters, additional amplifier and crossovers are required for this. This lead is for cars with the Harman/Kardon amplifier, this will not work for cars with the Harman/Kardon LOGIC7 system, these cars will have a different speaker setup.
Using with a InCarTec steering wheel control interface
This amplifier bypass cable can be used in conjunction with a steering wheel control interface (29-658 or 29-712) When using with a steering wheel control interface, it is only necessary to connect the brown speaker ISO from the 20-308 to the new radio, and connect just the green connector at the amplifier. The black power ISO to grey connector cable can be ignored. When connecting the steering control interface at the radio, only connect the black power ISO to the radio, ignore the brown speaker ISO from the steering control interface. By connecting like this, the 20-308 amp bypass cable is connecting the speakers, and the steering control interface is connecting the power.
