4.2 Connexions de cablejat
Connecteu els cables dels altaveus al vostre amplifier or head unit. Observe correct polarity: connect the positive (+) terminal of the speaker to the positive output of the amplifier, and the negative (-) terminal of the speaker to the negative output. Incorrect polarity can lead to poor sound quality and reduced bass response.
- Positive Connection: Typically marked with a red wire or a '+' symbol.
- Connexió negativa: Typically marked with a black wire or a '-' symbol.
4.3 Tweeter Adjustment
The ICU-165 speakers feature an AI/Mg inverted dome tweeter with a switch for adjusting the high-frequency response. This switch allows you to select between 'FLAT' and 'HIGH' settings to optimize the sound based on your listening preference and vehicle acoustics.

- PIS: Provides a neutral high-frequency response.
- ALTA: Boosts high frequencies for a brighter sound.
Experiment with both settings to find the one that best suits your audio system and personal taste.
5. Instruccions de funcionament
Once installed, operate your Focal ICU-165 speakers through your vehicle's head unit or amplifier. Start with low volume levels and gradually increase to your desired listening level. Avoid excessive volume that causes distortion, as this can damage the speakers.
- Ensure your head unit's equalizer and sound settings are configured appropriately for coaxial speakers.
- For optimal performance, consider using a high-pass filter to protect the speakers from very low frequencies if you have a separate subwoofer.
6. Manteniment
Focal ICU-165 speakers require minimal maintenance to ensure long-lasting performance.
- Neteja: Feu servir un drap suau i sec per netejar suaument la pols dels cons i les reixetes dels altaveus. Eviteu utilitzar productes químics agressius o netejadors abrasius.
- Inspecció: Comproveu periòdicament les connexions dels altaveus per assegurar-vos que estiguin ben ajustades i que no hi hagi cables desfilats o exposats.
- Factors ambientals: While the speakers have a water-resistant level, avoid direct exposure to excessive moisture or extreme temperatures.
7. Solució De Problemes
If you experience issues with your Focal ICU-165 speakers, refer to the following common problems and solutions:
| Problema | Causa possible | Solució |
|---|---|---|
| No hi ha so dels altaveus | Incorrect wiring, loose connections, amplifier off, head unit settings. | Check all wiring connections for proper polarity and tightness. Ensure amplifier is powered on and head unit output is enabled. |
| So distorsionat | Volume too high, incorrect gain settings on amplificador, altaveu danyat. | Baixa el volum. Ajusta amplifier gain settings. If distortion persists at moderate volumes, inspect speakers for physical damage. |
| Lack of bass | Incorrect wiring polarity, phase issues, inadequate enclosure. | Verify speaker wire polarity. Ensure speakers are in phase. While these are coaxial, proper mounting in a sealed environment helps bass response. |
| Harsh or dull treble | Tweeter adjustment switch setting, equalizer settings. | Adjust the 'FLAT' / 'HIGH' switch on the tweeter. Modify equalizer settings on your head unit. |
If the problem persists after attempting these solutions, contact your authorized Focal dealer or a qualified car audio technician.
