Infinity Reference 9630CX 6x9 Component Speaker System User Manual

1. Overview

The Infinity Reference 9630CX component speaker system is engineered to deliver Infinity's signature audio quality in a wide range of vehicles. This system features edge-driven textile tweeters for smooth, clear high-frequency reproduction. Larger models, including this one, incorporate an adjustable tweeter output level control, allowing for high-frequency optimization based on the installation location and listener preference. The oversized Plus One woofers provide increased surface area, resulting in higher bass output and enhanced midrange performance. The newly engineered baskets are designed for optimal fit in most factory speaker locations, making this system an ideal upgrade from standard factory speakers.

3.2 Woofer Installation

  1. Identify suitable mounting locations for the 6x9 inch woofers, typically in factory speaker cutouts in doors or rear decks.
  2. Ensure adequate clearance behind the mounting surface for the speaker magnet and basket.
  3. Connect the woofer wires to the passive crossover network. Observe correct polarity (+ to + and - to -).
  4. Secure the woofers using the provided mounting screws and speed clips.

3.3 Tweeter Installation

The system includes multiple mounting options for the tweeters:

  • Flush Mount: Requires cutting a circular hole in the mounting surface. Use the flush-mount cups and threaded adapters to secure the tweeter.
  • Surface Mount: Allows the tweeter to sit on top of the mounting surface. Use the surface-mount cups and screws.
  • Starfish Mount: Provides a flexible mounting solution, often used behind factory grilles or in tight spaces.

Connect the tweeter wires to the passive crossover network, ensuring correct polarity.

3.4 Crossover Network Installation

The passive crossover network separates the audio signal into appropriate frequency ranges for the woofer and tweeter. Mount the crossovers in a dry, secure location, away from excessive heat or moisture. Connect the input from your amplifier or head unit to the crossover's input terminals, then connect the woofer and tweeter outputs to their respective speakers.

3.5 Wiring Considerations

  • Ensure all wiring connections are secure and properly insulated to prevent short circuits.
  • Use appropriate gauge speaker wire for your installation.
  • Maintain correct polarity throughout the system to ensure proper phase and sound imaging.

4. Operating Your Speaker System

Once installed, the Infinity Reference 9630CX system is designed to provide a superior audio experience. The speakers feature a 3.0 ohm impedance, which allows them to draw more power from your amplifier for increased output.

4.1 Audio Characteristics

  • Highs: Experience smooth and clear high frequencies thanks to the edge-driven textile tweeters.
  • Midrange: Enhanced midrange performance is delivered by the oversized Plus One woofers.
  • Bass: The larger surface area of the woofers contributes to higher bass output.

4.2 Adjustable Tweeter Output Level

The crossover network includes an adjustable tweeter output level control. This feature allows you to fine-tune the high-frequency response to match your listening preferences and compensate for different tweeter mounting locations. Adjust the switch on the crossover to either 0dB or +3dB to increase the tweeter output if desired. Experiment with both settings to find the sound that best suits your vehicle's acoustics and personal taste.

5. Maintenance

The Infinity Reference 9630CX component speaker system requires 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. Inspect speaker cones and surrounds for any signs of damage or wear.
  • Environment: Protect speakers from extreme temperatures, direct sunlight, and excessive moisture.

6. Troubleshooting

If you encounter issues with your speaker system, refer to the following common problems and solutions:

ProblemPossible CauseSolution
No sound from speakersLoose or disconnected wiring; incorrect polarity; amplifier not powered on or faulty; head unit settings.Check all speaker and crossover connections. Ensure correct polarity. Verify amplifier and head unit are functioning correctly.
Distorted or unclear soundOverpowering speakers; incorrect gain settings on amplifier; damaged speaker cone/surround; poor signal source.Reduce amplifier gain or head unit volume. Check speaker for physical damage. Use a high-quality audio source.
Lack of bass or highsIncorrect crossover settings; phase issues; speaker placement.Verify crossover connections and tweeter output level setting. Ensure all speakers are wired in phase. Adjust speaker placement if possible.

If troubleshooting steps do not resolve the issue, contact Infinity customer support or a qualified car audio technician.
