Operation
Once installed, your Infinity Reference speakers will operate as part of your vehicle's audio system. Adjust audio settings on your head unit or amplifier to achieve desired sound quality.
Tweeter Output Level Adjustment:
The REF-3032CFX speakers feature an adjustable tweeter output level. This allows you to fine-tune the high-frequency response. Depending on your installation location and personal preference, you can set the tweeter output to 0dB (flat) or +3dB (boosted). Refer to your speaker's specific wiring diagram or the speaker itself for the adjustment switch or jumper location.
Maintenance
Your Infinity Reference speakers require minimal maintenance to ensure long-lasting performance.
- Cleaning: Use a soft, dry cloth to gently wipe the speaker grilles and cones. Avoid using harsh chemicals or abrasive cleaners.
- Protection: Ensure speakers are protected from direct sunlight, extreme temperatures, and moisture.
- Inspection: Periodically check speaker connections for any signs of corrosion or looseness.
Troubleshooting
If you experience issues with your speakers, consider the following common troubleshooting steps:
- No Sound: Check all wiring connections to ensure they are secure and correctly polarized. Verify that your amplifier or head unit is powered on and functioning.
- Distorted Sound: Reduce the volume level. Check for proper gain settings on your amplifier. Ensure speaker wires are not frayed or shorting.
- Weak Bass: Confirm correct polarity of speaker connections. Ensure the speakers are properly sealed in their mounting location.
- No High Frequencies: Check tweeter connections. Ensure the tweeter output level is not set to 0dB if you prefer a brighter sound.
If problems persist after attempting these steps, consult a professional car audio technician.
