Amplifier bypass cable for Range Rover sport and Discovery 3 cars with original Harman/Kardon LOGIC 7 premium sound system amplifiers under the driver's seat. Allows you to connect a new aftermarket radio directly to the car's speakers after bypassing the original amplifier.
A new extra amplifier will be needed to keep the original sub-woofers.

The bypass lead allows you to ignore the cars amplifier.

This car also needs a separate steering control interface.

This bypass lead will retain the front door speakers, the rear door speakers and the rear roof speakers. The centre speaker will be lost and a new amplifier will need to be added to retain the woofers in the tailgate.
