It is designed to reproduce lower-frequency audio within the rear cabin and works together with the other speakers and factory amplifier/audio equipment.

The assembly incorporates:

• Speaker driver

• Factory speaker basket

• Vehicle-specific mounting arrangement

• Factory electrical connection

• Door-specific acoustic mounting design

Harman Kardon Audio System Information

This speaker is documented as a Harman Kardon component. (eBay UK)

Depending on vehicle specification, the complete Discovery 4 audio system can include:

• Front door speakers

• Rear door speakers

• Tweeters / higher-frequency speakers

• Centre speaker

• Subwoofer

• Factory audio amplifier

• Radio / multimedia head unit

Audio equipment varies according to the sound-system specification fitted to the vehicle.

Common Symptoms / Reasons for Replacement

• Rear speaker not producing sound

• Distorted audio

• Crackling or buzzing

• Bass response significantly reduced

• Speaker cone damaged

• Speaker rattling at higher volume

• Intermittent sound

• Internal voice-coil failure

• Electrical connector damaged

• Water / moisture damage

• Original speaker missing after door replacement

Important Diagnostic Information

Before replacing the speaker, check:

• Audio balance and fade settings

• Factory amplifier operation

• Door wiring loom

• Speaker electrical connector

• Head unit / multimedia operation

• Speaker wiring continuity

A rear speaker that produces no sound does not automatically mean the speaker itself has failed.

Wiring, connectors and amplifier channels can produce similar symptoms.

Installation

Designed to fit into the original rear-door speaker mounting location.

Installation normally requires removal of the rear interior door card.

During installation:

• Compare the replacement speaker with the original

• Check 5H22-70451-NB / XQM500530

• Inspect the electrical connector

• Secure all original mounting points

• Ensure the speaker sits correctly against the door

• Route wiring correctly

• Refit the door card carefully

Programming / Coding

No programming or coding is normally required when replacing the speaker with the correct like-for-like unit.

The speaker is a direct audio component and does not contain a separately programmable vehicle control module.

Important Compatibility Note

⚠️ Please match the speaker number and audio-system specification before purchasing.

Confirm:

• 5H22-70451-NB

• 5H2270451NB

• XQM500530 where applicable

• Speaker size and basket design

• Electrical connector

• Mounting points

• Harman Kardon audio specification

• Listing photographs

Discovery 4 vehicles were available with different audio configurations and other speakers from the same 5H22-70451 family exist. For example, 5H22-70451-HB / XQM500480 is documented as a different front-door bass speaker. (GlobalParts)

Do not purchase solely by vehicle model and year. Match the original speaker number wherever possible.
