Land Rover Meridian 400W Sound System Retrofit

The LR‑Retrofit Meridian 400W sound system retrofit delivers authentic, concert‑hall audio quality inside your Land Rover or Range Rover. This genuine‑specification upgrade replaces the standard audio setup with a 13‑speaker Meridian system, a dedicated subwoofer and a sophisticated digital amplifier. Every component mirrors the factory‑fitted premium system, ensuring perfect integration with your vehicle’s infotainment and cabin acoustics.

What is the Meridian 400W Sound System?

The Meridian 400W system is a high‑resolution audio package developed jointly by Jaguar Land Rover and Meridian Audio. It uses 13 individually driven speakers, a 400‑watt digital amplifier and a closed‑box subwoofer to create a balanced, three‑dimensional soundstage. Meridian’s proprietary Digital Signal Processing (DSP) tailors the output to the exact cabin dimensions of your Land Rover model. The result is a pure, dynamic listening experience with precise instrument placement and deep, controlled bass. This system brings the studio master’s intent to every journey.

Key Benefits

• Immersive Soundstage: 13 speakers, including centre‑channel and surround drivers, position every note with pinpoint accuracy. The sound wraps around you without losing clarity.
• Deep, Controlled Bass: A dedicated subwoofer in a tuned enclosure produces tight, distortion‑free low frequencies. You feel the rhythm without any cabin rattle.
• Trinnov Optimisation Technology: Meridian’s Trinnov processing analyses the acoustic environment and corrects phase and timing errors. The system delivers a natural, fatigue‑free listening experience at any volume.
• Seamless OEM Integration: The upgrade integrates directly with the Touch Pro or Pivi Pro infotainment. You access Meridian‑specific audio settings, surround modes and equaliser curves through the factory screen.
• Pure Digital Amplification: The 400‑watt Class‑D amplifier maintains an ultra‑low noise floor and high efficiency. Every channel receives a clean, distortion‑free signal.
• Resale Value Enhancement: A factory‑matched Meridian audio system is a highly desirable option. The retrofit adds tangible value and appeal to your vehicle.
