Hello to all owners of Range Rover Sport. I decided to upgrade base audio system 380 W up to Meridian 825 W on my RRS 2017. My car looks like RRS 2014, but with InControl Touch 10 inside. I`ve bought an amplifier AUD4-16 HPLA-19C164-CDC +18 speakers +Sub from RRS SVR 2017 model year. But I couldn't find the wiring diagram for that Meridian system as I need correctly connect existing and new speakers to the new amplifier. I need your help as I am going to implement this upgrading nearest weekends.

Hi guys. I did it and now the music in my car sounds incredibly great. Although Land Rover dealers and service centers refused to reprogram my car`s head unit, the world is not without kind and smart people. I am very pleased because it all cost me $ 1,000, including an amplifier, 19 speakers, installation and reprogramming works. It was worth it.

Good effort

Not something I’d fancy tackling. But I’m well and truly in the ‘old git’ category these days and generally listen to talk radio stations, so the effort wouldn’t be for much gain.
