Key Benefits

Improves vocal clarity and instrument detail in the upper frequency range. Simple mechanical fitment for quick service times in door trim, dash or A-pillar locations depending on original vehicle layout. Helps eliminate distortion, rattles and reduced output caused by failed tweeter diaphragms or voice coils.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Peugeot 206
• Product Codes: 9640322880, 9666384580
• Other Numbers: 6562G9, 6262A8

Compatibility And Fitment

Primary fitment is Peugeot 206 (various body styles and equipment levels). Use the OEM product codes above to confirm direct replacement fitment for the vehicle. This tweeter is intended to replace the original high-frequency driver without modification when the part numbers match.

Function And Typical Failure Causes

Tweeters reproduce the high-frequency portion of the audio spectrum, adding clarity to voices, cymbals and other high-frequency content. Common causes of failure include:

• Overload or Distortion: Excessive volume or amplifier clipping can burn the voice coil.
• Moisture Ingress: Water or condensation in door/a-pillar areas leads to corrosion and membrane damage.
• Physical Damage: Impact during door removal/installation or panel replacement can deform the dome.
• Ageing And Wear: Long-term heat and UV exposure degrade diaphragms and adhesives.
• Electrical Faults: Faulty crossover components or amplifier issues can reduce output or damage the tweeter.

Installation Recommendations

Recommended for installation by trained technicians or experienced DIYers. General replacement steps:

• Remove Interior Trim: Carefully remove the door panel, A-pillar trim or dash grille to access the tweeter. Use appropriate trim tools to avoid damaging clips.
• Disconnect Power Sources As Needed: For safety, isolate the audio system (turn ignition off). Disconnecting the vehicle battery is optional for speaker replacement but recommended if you will work near airbags or vehicle electronics.
• Unplug Connector: Disconnect the tweeter electrical connector. Note connector orientation and clip positions for reassembly.
• Remove Mounting Hardware: Unscrew or unclip the tweeter from its mounting bracket or housing.
• Install New Unit: Fit the replacement tweeter, secure mounting hardware and reconnect the electrical connector with correct polarity.
• Test Audio: Before reassembling trim, test the speaker at moderate volume to verify correct operation and polarity. Refit trim panels ensuring no pinched wiring.

Why Replace The Tweeter

Replacing a failed tweeter restores the high-frequency balance of the audio system and prevents listener fatigue caused by distortion or missing frequencies. Replacing only the failed driver is cost-effective compared with full speaker set replacements when other speakers are still in good condition.

Search And Identification Tips

Customers and workshops commonly search by OEM codes 9640322880, 9666384580, 6562G9 and 6262A8. Including these numbers in your search will increase the chance of finding the exact replacement part. Use clear photos of the existing tweeter and connector when in doubt.

Notes For Workshops

Keep replacement tweeters in stock by common OEM number to minimize vehicle downtime. When replacing speakers on vehicles with factory amplifiers or active crossovers, verify amplifier settings and polarity to avoid damage to the new driver.

Installation Recommendation

Intended for fitment by trained mechanics or experienced DIYers. Typical installation steps:

• Gather tools: adjustable wrench or suitable socket, trim removal tools, cleaning cloth, dielectric grease or anti-seize.
• Access the antenna base from inside the roof lining if required (some models allow external unscrewing of the mast). Remove any interior trim carefully to reach the mounting nut.
• Unscrew the old mast from the base or remove the securing nut underneath the roof liner. Inspect the base, cable connector and seal.
• Clean mating surfaces and cable contacts. Apply a small amount of dielectric grease to the connector to prevent corrosion.
• Fit new sealing washer or gasket if available, screw the new mast into the base or secure the base with the nut. Do not overtighten—ensure a firm, watertight fit.
• Reinstall interior trim, test radio reception and check for water ingress after a wash or rain.

Why The Part Commonly Fails

• Mechanical Damage: Mast frequently bent or broken by automated car washes, low garage entrances, branches or vandalism.
• Corrosion: Thread and connector corrosion from long-term exposure to moisture reduces electrical contact and makes removal difficult.
• Seal Degradation: Deteriorated rubber gasket allows water ingress, leading to connector corrosion and poor reception.
• Poor Contact: Loose or oxidised connector at the base causes intermittent or weak signal.

Notes: When replacing the antenna, always check the condition of the base, cable and sealing washer. Replacing the gasket when fitting a new mast prevents future water leaks. After installation verify radio reception across AM and FM bands and ensure the mount is secure to avoid vibration noise.
