6. Setup and Installation
Proper installation is crucial for optimal performance and safety. It is highly recommended that installation be performed by a qualified car audio professional.
6.1 Mounting Considerations
- Location: Choose a mounting location that provides sufficient depth and clearance for the speaker. Refer to the "Mounting Depth" and "Cutout Dimensions" in the specifications.
- Enclosure: These mid-bass speakers perform best in a properly sealed or ported enclosure designed for their specific parameters. Consult with an audio specialist for custom enclosure designs if needed.
- Secure Mounting: Use appropriate hardware to securely fasten the speakers to prevent vibrations and ensure stable performance.

6.2 Wiring Instructions
The LW-80A4 features a 4-ohm Single Voice Coil (SVC) design. Proper wiring is essential to match the speaker's impedance with your amplifier's output capabilities.
- Speaker Terminals: Connect the positive (+) terminal of the speaker to the positive (+) output of your amplifier. Connect the negative (-) terminal of the speaker to the negative (-) output of your amplifier.
- Wire Gauge: Use appropriate gauge speaker wire (e.g., 14-16 gauge for typical installations) to minimize power loss and ensure clear signal transmission.
- Multiple Speakers: When wiring multiple speakers, ensure the final impedance presented to the amplifier is within its stable operating range. For two 4-ohm SVC speakers:
- Parallel Wiring: Connect positive to positive, and negative to negative. This results in a 2-ohm load (4 ohms / 2 speakers = 2 ohms).
- Series Wiring: Connect the positive of one speaker to the negative of the other. Connect the remaining positive and negative to the amplifier. This results in an 8-ohm load (4 ohms + 4 ohms = 8 ohms).
- Insulation: Ensure all connections are tightly secured and properly insulated to prevent short circuits.

7. Operating Instructions
Once installed, follow these guidelines for optimal operation:
- Initial Power-Up: Start with the amplifier's gain settings at their lowest. Gradually increase the volume and gain to a comfortable listening level, ensuring no distortion is present.
- Amplifier Matching: Ensure your amplifier's RMS power output is within the recommended range for the LW-80A4 speakers (100W RMS). Overpowering or underpowering can lead to speaker damage.
- Crossover Settings: Utilize your amplifier's or head unit's crossover settings to filter out frequencies outside the speaker's optimal range (29 - 4000 Hz). A high-pass filter set around 60-80 Hz is typically recommended for mid-bass speakers to prevent over-excursion at very low frequencies.
- Avoid Distortion: If you hear any distortion, reduce the volume or gain immediately. Distortion indicates that the amplifier or speakers are being overdriven, which can cause permanent damage.
8. Maintenance
The Deaf Bonce LW-80A4 speakers require minimal maintenance to ensure long-term performance:
- Cleaning: Periodically wipe the speaker cones and surrounds with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
- Inspection: Regularly inspect the speaker surrounds and cone for any signs of damage, tears, or deterioration. Check wiring connections for tightness and corrosion.
- Environmental Factors: Protect speakers from extreme temperatures, direct sunlight, and excessive moisture, which can degrade materials over time.
9. Troubleshooting
If you encounter issues with your speakers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from speaker |
|
|
| Distorted or unclear sound |
|
|
| Weak or absent bass |
|
|
If the problem persists after attempting these solutions, contact customer support or a qualified technician.
