The JBL amplifier is from Citroën C5 II and is suitable for Peugeot 607 and other models.
High-quality OEM JBL amplifier unit designed for factory audio systems in selected Citroën and Peugeot vehicles. This replacement amplifier restores full audio performance — clearer highs, richer mids and deeper bass — where the original unit has failed or produces distorted sound. Technically minded mechanics and DIY enthusiasts often search for this part by its product number, so key identifiers are included below to help you find the correct unit quickly.
Technical Information
- Manufacturer: JBL (OEM Supplier)

Installation Recommendations
- Disconnect the negative battery terminal before starting to avoid short circuits or triggering vehicle electronics.
- Access the amplifier location according to the vehicle model — commonly found under a seat, in the trunk, or behind interior trim panels. Remove surrounding trim and fasteners carefully to avoid breakage.
- Document connector positions and speaker wiring before unplugging. Take photos if necessary to ensure correct reconnection.
- Inspect wiring harness and speaker connectors for corrosion or damage; repair any damaged connectors or wiring before fitting the new amplifier.
- After installation, verify grounding and battery voltage. Some vehicles may require a brief ignition cycle or radio initialization; in a few cases, radio coding or module initialization may be needed for full functionality.
- Handle the unit with care to avoid electrostatic discharge (ESD) and avoid exposing the amplifier to moisture during installation.
Common Reasons For Failure
- Water Ingress: Moisture from leaks or condensation can corrode internal electronics and connectors.
- Electrical Surges: Faulty alternator, jump-start procedures, or short circuits can damage amplifier components.
- Speaker Short Circuits: Damaged speaker wiring or shorted speaker coils place excessive load on the amplifier.
- Connector Corrosion Or Poor Contacts: Oxidation or loose pins cause intermittent sound or complete failure.
- Thermal Stress: Extended high-volume use or blocked ventilation can lead to thermal shutdowns or permanent damage.
Practical Notes
If the audio system exhibits distortion, channel dropout, or no sound from multiple speakers, the amplifier is a likely culprit. Replacing the amplifier usually restores multi-channel functionality, but always confirm speaker and wiring integrity before replacement to avoid repeat failures. Use the product code (9631041580) when searching or ordering to ensure compatibility with the vehicle’s factory JBL system.
Suitable For: Citroën C5 II, Peugeot 607, Peugeot 407 and other compatible Stellantis models. Commonly referenced by part numbers 9631041580, 6560LZ, and NFP.
