Description
Antenna Amplifier AM/FM1 For Citroën And Peugeot Vehicles
This Antenna Amplifier AM/FM1 is designed for Citroën and Peugeot vehicles to improve radio reception and signal stability for AM and FM bands. Ideal for workshops and DIY mechanics looking for a direct replacement part, this amplifier restores weak or intermittent radio reception caused by a faulty aerial amplifier or damaged connections. Commonly referenced by part numbers 9657017980 and 6561JV, it fits vehicles originally equipped with the AM/FM1 antenna system.
Product Overview
The antenna amplifier boosts low-level radio signals before they reach the head unit, improving clarity, reducing noise and increasing range for both AM and FM reception. It is a compact electronic module mounted close to the vehicle antenna or within the roof area, depending on the model. Symptoms of a failing amplifier include weak reception, intermittent signal loss, static, or complete absence of AM/FM radio reception while other audio sources remain unaffected.

Installation Recommendation
Before Starting: Always disconnect the vehicle battery before beginning work on any electrical component to avoid short circuits and prevent damage to the amplifier or vehicle electronics. Follow manufacturer removal procedures for access to the unit.
- Locate The Unit: The amplifier is typically mounted close to the antenna base, under the headliner, inside the roof module, or in a rear-quarter area depending on the vehicle. Remove interior trim or headliner sections as required to access the module.
- Disconnect Connectors: Carefully unplug antenna coaxial plugs and electrical connectors. Inspect connectors and wiring for corrosion or damage.
- Remove Old Unit: Unscrew or unclip the amplifier from its bracket. Preserve any mounting hardware needed for installation.
- Fit New Unit: Mount the replacement amplifier in the original position. Reconnect coaxial and electrical connectors ensuring secure, corrosion-free contacts.
- Test Before Reassembly: Reconnect the battery and test radio reception and functionality before reinstalling trim. Confirm improved reception on AM and FM bands and check for any interference or noise.
- Final Steps: Once functionality is verified, reassemble interior panels and ensure all clips and screws are secured.
Why It Most Commonly Fails
The most frequent causes of antenna amplifier failure are water ingress and corrosion at the antenna base or connector points, physical damage to the aerial or coaxial cable, thermal stress from repeated heating and cooling cycles, and electrical spikes (for example after lightning strikes or poor grounding). Aging components and poor connector contacts can cause intermittent faults that are difficult to diagnose without inspection. In many cases, replacing the amplifier and repairing corroded connectors or damaged coaxial cable restores reliable reception.
Practical Tips For Mechanics And DIYers
- Always Inspect The Antenna Mast And Coaxial Cable For Damage Or Corrosion When Replacing The Amplifier.
- Clean Connectors With Contact Cleaner And Use Dielectric Grease On External Connections To Prevent Future Corrosion.
- When Replacing Roof-Mounted Units, Work With A Helper To Avoid Creasing Or Damaging The Headliner.
- Test The Radio With The Vehicle Stationary And While Driving To Confirm Real-World Reception Improvement.
