Meridian’s 400‑Watt Digital Architecture
The Meridian 400W system elevates the base audio beyond a simple speaker swap. A 10‑channel fully digital amplifier powers 12 individually tuned speakers plus a trunk‑mounted subwoofer. Meridian’s intelligent DSP continuously adapts the output to the exact cabin environment of your Discovery Sport, Range Rover Evoque, Range Rover Velar, or Jaguar E‑Pace. You hear crisp highs, a seamless mid‑range, and powerful, distortion‑free bass — even at motorway speeds.
Meridian’s patented Trifield technology re‑creates a three‑dimensional sound field from any stereo source. The system routes dedicated centre‑channel information through the dashboard speaker, locking vocals and instruments precisely where the artist placed them. Simultaneously, Meridian’s Dynamic Volume Control subtly adjusts the output as road speed changes, so every podcast, every playlist, and every phone call remains perfectly intelligible.
Complete OEM‑grade Specification
- Total power: 400 watts RMS (10‑channel amplifier with digital signal processing).
- Speaker count: 12 neodymium‑magnet midrange/treble units plus a long‑throw 200mm subwoofer in a tuned enclosure.
- Digital sampling: 48 kHz / 24‑bit digital path from source to speaker — zero analogue conversion loss.
- Trifield DSP: dedicated centre channel, proprietary time‑alignment, and phase correction for a natural, immersive image.
- Dynamic Volume Control: road‑speed‑dependent equalisation that compensates for tyre and wind noise without blunting transient detail.
- Premium woven‑cone drivers: lightweight glass‑fibre composite cones with rubber surrounds for long‑term resilience and minimal distortion.
- Amplifier topology: Class‑D efficiency with a direct‑to‑battery power supply, delivering headroom for the most demanding modern recordings.
What You Immediately Gain
Your vehicle’s cabin instantly becomes a curated listening room. Stereo separation expands beyond the physical width of the car; bass lines remain tight and articulate, never muddy. The factory‑loaded DAB, Bluetooth, and USB sources all benefit from Meridian’s proprietary up‑sampling, so even compressed streams sound richer and more dimensional. Because the system uses the vehicle’s existing CAN bus and MOST (or Ethernet) audio network, you access every function through your factory touchscreen — no secondary controller or fiddly aftermarket remote.
Retrofit Process: Plug‑and‑Play, Coded to Perfection
Our JLR‑certified technicians install every Meridian‑branded speaker, the digital amplifier, and the subwoofer enclosure using the original mounting positions and factory wiring looms. We then perform a full CCF (Car Configuration File) update with the genuine Pathfinder diagnostic tool, enabling the Meridian sound system audio mode in the vehicle’s Infotainment Master Controller. This step unlocks the system’s full digital capability — tonal balance, Trifield effect, Dynamic Volume threshold — exactly as the factory intended. Finally, we run a vehicle‑specific audio calibration routine that measures each speaker’s time‑of‑flight and equalises the cabin response.
The entire conversion fits invisibly behind the standard door cards and trim. You retain every single function of your Pivi Pro or InControl Touch Pro screen, together with full OTA update compatibility. After installation, the sound menu displays the genuine Meridian branding, and the 3D sound toggle appears just as it would in a factory‑high‑spec model.
