- Drill pilot holes for the mounting screws.
- Secure the speaker using appropriate screws, ensuring a snug fit without overtightening.
3.3 Wiring
- Connect the speaker wires from your amplifier to the speaker terminals. Ensure correct polarity (positive to positive, negative to negative).
- Use high-quality speaker wire of adequate gauge for your system.
- Insulate all connections to prevent short circuits.
- Once all connections are made, reconnect the vehicle's battery.

4. Operating Instructions
Once installed, your Nemesis NA-6.5M speakers are ready for use. Follow these general guidelines for optimal audio experience:
- Initial Power-Up: Start with the amplifier gain set to its lowest level. Gradually increase the volume to a comfortable listening level.
- Audio Source: Use high-quality audio sources (e.g., uncompressed digital files) for the best sound reproduction.
- Equalization: Adjust your head unit's or amplifier's equalizer settings to fine-tune the sound to your preference. Avoid excessive boosting of frequencies, which can lead to distortion.
- Volume Levels: While the speakers are designed for high power, prolonged listening at maximum volume can cause listener fatigue and potential speaker damage. Listen responsibly.
- Break-in Period: Allow a short break-in period (typically 10-20 hours of normal use) for the speaker components to loosen up and achieve their full sound potential.
5. Maintenance
Regular maintenance helps preserve the performance and appearance of your speakers.
- Cleaning: Use a soft, dry cloth to gently wipe down the speaker cones and surrounds. Avoid using harsh chemicals or abrasive materials.
- Inspection: Periodically check speaker connections for tightness and ensure no wires are frayed or exposed.
- Environmental Factors: Protect speakers from extreme temperatures, direct sunlight, and excessive moisture.
6. Troubleshooting
If you encounter issues with your Nemesis NA-6.5M speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | Loose or incorrect wiring; amplifier off or faulty; head unit issue. | Check all speaker and amplifier connections. Ensure amplifier is powered on and functioning. Verify head unit output. |
| Distorted Sound | Amplifier gain too high; damaged speaker; incorrect equalization settings. | Reduce amplifier gain. Check speaker cone for physical damage. Adjust equalizer settings to neutral or slightly boosted. |
| Weak or Muffled Sound | Incorrect speaker polarity; low power input; poor audio source quality. | Verify speaker wire polarity. Ensure amplifier is providing adequate power. Use higher quality audio files. |
| Intermittent Sound | Loose connections; faulty wiring; amplifier overheating. | Check and secure all connections. Inspect wiring for damage. Ensure amplifier has proper ventilation. |
If the problem persists after attempting these solutions, contact customer support or a qualified car audio technician.
