5. Installation Guide

5.1 Pre-Installation Considerations

• Vehicle Compatibility: Ensure the CX100 speakers are compatible with your vehicle's speaker openings. Adapters may be required for certain vehicle models (e.g., BMW E91, Porsche 996).
• Tools Required: Basic hand tools (screwdrivers, wire strippers, crimpers), drill (if new holes are needed), and safety glasses.
• Amplification: These speakers ideally require 30-50W RMS delivery from an amplifier. Consider a 120-150Hz High-Pass Filter (HPF) to optimize sound quality.

5.2 Mounting Instructions

1. Access Speaker Location: Carefully remove door panels or dashboard components to access the factory speaker locations. Refer to your vehicle's service manual for specific instructions.
2. Remove Old Speakers: Disconnect wiring and unmount the existing speakers.
3. Test Fit: Place the CX100 speakers into the opening to ensure a proper fit. If necessary, use speaker adapters.
4. Wiring: Connect the speaker wires. Ensure correct polarity (positive to positive, negative to negative). The CX100 speakers have an impedance of 4 Ohm.
5. Secure Speakers: Mount the CX100 speakers using the provided screws. Ensure they are securely fastened to prevent vibrations.
6. Reassemble: Reinstall vehicle components, ensuring no wires are pinched.

6. Operation

Once installed, the HERTZ CX100 speakers will reproduce audio from your car's head unit or amplifier. For optimal sound quality, ensure your audio source is properly configured. Adjust bass, treble, and balance settings on your head unit to suit your listening preferences. Avoid excessively high volumes that can lead to distortion or speaker damage.

7. Maintenance and Care

• Cleaning: Use a soft, dry cloth to clean the speaker cones and surrounds. Do not use harsh chemicals or abrasive cleaners.
• Inspection: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed.
• Environment: While designed for vehicle use, avoid prolonged exposure to extreme heat or direct sunlight, which can degrade speaker materials over time. The speakers are not water resistant.

8. Troubleshooting

If you encounter issues with your HERTZ CX100 speakers, refer to the following common problems and solutions:

• No Sound:
  • Check all wiring connections for proper contact and polarity.
  • Verify that the amplifier (if used) is powered on and functioning.
  • Ensure the head unit is powered on and outputting audio.
• Distorted Sound:
  • Reduce the volume level. Excessive volume can cause distortion.
  • Check for loose connections or damaged speaker wires.
  • Ensure the amplifier gain settings are not too high.
  • Verify that the speakers are securely mounted and not vibrating against other surfaces.
• One Speaker Not Working:
  • Check the wiring for that specific speaker.
  • Swap the speaker with a working one (if possible) to determine if the issue is with the speaker or the wiring/source.
