Setup and Installation
Proper installation is crucial for optimal sound performance and speaker longevity. If you are unsure about any step, consult a professional installer.
1. Safety Precautions
- Disconnect the vehicle's battery before starting any electrical work.
- Wear appropriate safety gear, including eye protection.
- Ensure all wiring is properly insulated to prevent short circuits.
2. Mounting Location
These 6x9 inch coaxial speakers are designed for car audio applications. Ensure the chosen mounting location in your vehicle provides sufficient depth and clearance for the speaker.
- Top-mount Depth: 3-1/8 inches (79.4 mm)
- Cutout Dimensions: 8-1/2 inches x 5-3/4 inches (215.9 mm x 146.1 mm)
Verify these dimensions against your vehicle's speaker openings. Some vehicles may require adapter plates or minor modifications for a proper fit.

3. Wiring Connections
Connect the speaker wires from your car stereo or amplifier to the terminals on the back of the speaker. Observe correct polarity: positive (+) to positive and negative (-) to negative. Incorrect polarity can lead to poor sound quality and reduced bass response.

The speakers feature a 3-ohm impedance. This "True 4-Ohms" impedance technology is optimized for compatibility with aftermarket car stereos, allowing them to draw more power safely for enhanced performance.
4. Securing the Speakers
Once wired, carefully place the speakers into their mounting locations and secure them using the provided screws and clips. Ensure a snug fit to prevent vibrations and rattles.

Operating Instructions
The Infinity Reference REF-9633IX speakers are designed to work with your car's audio system. No specific operational controls are present on the speakers themselves.
1. Power Handling
- RMS Power Handling: 100 Watts per speaker (200 Watts per pair)
- Peak Power Handling: 300 Watts per speaker (600 Watts per pair)
Ensure your amplifier or head unit's power output is within these specifications to prevent damage to the speakers. Operating speakers beyond their rated power handling can lead to distortion and permanent damage.
2. Audio Settings
Adjust the audio settings on your car stereo or amplifier (e.g., bass, treble, balance, fader) to achieve your preferred sound. Start with flat settings and make small adjustments. The speakers are designed for a broad frequency response, providing clear highs and robust lows.
Maintenance
These speakers require minimal maintenance to ensure long-lasting performance.
- Cleaning: Use a soft, dry cloth to gently wipe dust from the speaker grilles and cones. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically check speaker connections for any loose wires or corrosion.
- Environment: Avoid exposing speakers to extreme temperatures or excessive moisture.
Troubleshooting
If you experience issues with your speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose wiring connection; incorrect polarity; amplifier/head unit issue; speaker damage. | Check all wiring connections for tightness and correct polarity. Verify amplifier/head unit is powered on and functioning. Test with another known-good speaker if possible. |
| Distorted Sound | Overpowering speakers; incorrect audio settings; loose mounting; damaged speaker cone. | Reduce volume. Adjust bass/treble settings on your stereo. Ensure speakers are securely mounted. Inspect speaker cones for visible damage. |
| Weak Bass | Incorrect wiring polarity; insufficient power; audio settings. | Verify correct wiring polarity. Ensure amplifier provides adequate power. Adjust bass settings on your stereo. |
| Rattling Noise | Loose mounting; objects vibrating against speaker. | Tighten all mounting screws. Check for any loose panels or objects near the speaker that may be vibrating. |
