Setup and Installation
Proper installation is crucial for optimal performance. It is recommended that installation be performed by a qualified professional. Always disconnect the vehicle's battery before beginning any electrical work.
Woofer Installation

Mount the 6.5-inch woofers securely in the designated speaker locations in your vehicle's doors or panels. Ensure a tight fit to prevent vibrations and rattles. Use the provided mounting hardware.
Tweeter Installation

Install the tweeters in a location that provides optimal sound imaging, typically at ear level or slightly above. Various mounting options (flush, surface, or angle) may be available depending on your vehicle and the tweeter's design. Connect the tweeter wires to the crossover.
Crossover Connection
The external crossover filters are essential for directing the correct frequency ranges to the woofers and tweeters. Connect the input terminals of the crossover to your amplifier or head unit's speaker outputs. Then, connect the woofer output from the crossover to the 6.5-inch woofer and the tweeter output to the tweeter. Ensure correct polarity (+ to + and - to -) for all connections.
Speaker Grilles

Once the woofers are installed, attach the protective speaker grilles. These grilles protect the speaker cones from accidental damage.
Magnet Boot Cover

The protective magnet boot cover should be placed over the woofer's magnet structure. This provides additional protection and a clean aesthetic finish.
Operating Your Speakers
After installation, ensure all connections are secure before powering on your audio system. Start with the volume at a low level and gradually increase it to your desired listening level. Adjust the audio settings (bass, treble, balance, fader) on your head unit or amplifier to fine-tune the sound to your preference. Avoid excessive volume levels for prolonged periods to prevent speaker damage and hearing loss.
Maintenance
Your Focal RSE-165 speakers require minimal maintenance to ensure long-lasting performance.
- Cleaning: Gently wipe the speaker grilles and surrounds with a soft, dry cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the speaker components.
- Inspection: Periodically check all wiring connections to ensure they remain secure. Loose connections can lead to poor sound quality or intermittent operation.
- Environment: While designed for automotive use, avoid exposing the speakers to extreme moisture or direct sunlight for extended periods, as this can degrade materials over time.
Troubleshooting
If you experience issues with your Focal RSE-165 speakers, refer to the following common troubleshooting steps:
- No Sound:
- Check all wiring connections from the head unit/amplifier to the crossover, and from the crossover to the speakers. Ensure no wires are loose or disconnected.
- Verify the amplifier or head unit is powered on and functioning correctly.
- Check the audio source and volume settings.
- Distorted Sound:
- Reduce the volume level. Distortion often occurs when the amplifier or speakers are overdriven.
- Check for loose speaker cones or damaged surrounds.
- Ensure the amplifier gain settings are not set too high.
- One Speaker Not Working:
- Inspect the wiring for the non-working speaker, including connections at the speaker, crossover, and amplifier.
- Swap the non-working speaker with a known good one (if possible) to determine if the issue is with the speaker or the wiring/source.
- Lack of Bass or Treble:
- Check the polarity of the speaker connections. Incorrect polarity can cause phase cancellation, leading to reduced bass response.
- Adjust the bass and treble settings on your head unit or amplifier.
- Ensure the crossover is correctly wired and functioning.
If these steps do not resolve the issue, contact Focal customer support or a professional car audio technician.
