• 2x Gravity Warzone WZ10D4 Subwoofers

3. Safety Information

Always observe the following safety precautions during installation and operation:

• Disconnect the vehicle's battery before beginning any electrical work to prevent short circuits.
• Ensure proper ventilation for the subwoofer and amplifier to prevent overheating.
• Use appropriate gauge wiring for power, ground, and speaker connections to handle the current and power output.
• Avoid installing the subwoofer in locations where it may be exposed to moisture or extreme temperatures.
• Securely mount the subwoofer to prevent movement during vehicle operation, which could cause damage or injury.
• Prolonged exposure to high sound pressure levels can cause permanent hearing damage. Adjust volume levels responsibly.

4. Setup and Installation

Proper installation is crucial for optimal performance and longevity of your subwoofers. If you are unsure about any part of the installation process, consult a professional car audio installer.

4.1 Enclosure Requirements

These subwoofers are designed for use in sealed or ported enclosures. Refer to the subwoofer's technical specifications for recommended enclosure volumes. Ensure the enclosure is robust and sealed properly to prevent air leaks.

4.2 Mounting

Mount the subwoofer securely within the chosen enclosure using appropriate screws. Ensure there is no interference with the cone's movement and that the subwoofer gasket creates a tight seal with the enclosure.

4.3 Wiring Connections

The WZ10D4-1 features a dual 4-ohm voice coil configuration. This allows for various wiring options to achieve different impedance loads at your amplifier. Common configurations include:

• 1 Ohm Load: Wire both voice coils in parallel.
• 2 Ohm Load: Wire each subwoofer's voice coils in series (8 ohms per sub), then wire the two subwoofers in parallel (4 ohms total). Or, wire each subwoofer's voice coils in parallel (2 ohms per sub), then wire the two subwoofers in series (4 ohms total). For a single subwoofer, wire the two 4-ohm voice coils in parallel to achieve a 2-ohm load.
• 8 Ohm Load: Wire both voice coils in series.

Always match the final impedance load to your amplifier's stable operating range. Incorrect wiring can damage your amplifier or subwoofers.

4.4 Amplifier Selection

Select an amplifier that can provide sufficient RMS power within the recommended range for the WZ10D4-1 subwoofers (400 watts RMS each). Ensure the amplifier is stable at the impedance load presented by your wiring configuration.

5. Operating Instructions

Once installed, operate your subwoofers by following these guidelines:

• Initial Power-Up: After installation, turn on your car audio system at a low volume. Gradually increase the volume and check for proper operation and sound quality.
• Gain Setting: Adjust the gain control on your amplifier carefully. Do not use the gain control as a volume knob. Set it to match the output voltage of your head unit to prevent distortion.
• Crossover Settings: Utilize the low-pass filter (LPF) on your amplifier or head unit to send only low frequencies to the subwoofers. A common starting point is 80-100 Hz.
• Break-in Period: Allow a break-in period of approximately 20-30 hours of normal listening before operating the subwoofers at their maximum potential. This allows the suspension components to loosen up, improving performance.

6. Maintenance

Minimal maintenance is required for your subwoofers to ensure long-term performance:

• Cleaning: Periodically wipe the subwoofer cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
• Inspection: Regularly inspect the wiring connections for tightness and corrosion. Check the subwoofer surround for any signs of damage or deterioration.
• Environmental Factors: Protect the subwoofers from direct sunlight, extreme temperatures, and moisture, which can degrade materials over time.

7. Troubleshooting

If you experience issues with your subwoofers, refer to the following common troubleshooting steps:

• No Sound:
  • Check all power, ground, remote, and speaker connections for proper contact.
  • Verify the amplifier is powered on (check power indicator light).
  • Ensure the head unit is sending an audio signal.
  • Check amplifier fuses and vehicle fuses.
• Distorted Sound:
  • Reduce the amplifier gain.
  • Check for proper crossover settings; ensure only low frequencies are sent to the subwoofer.
  • Verify the impedance load matches the amplifier's stable operating range.
  • Ensure the subwoofer is not over-powered or under-powered.
• Weak Bass:
  • Check amplifier gain and subwoofer level settings on the head unit.
  • Verify correct wiring polarity (+ to + and - to -).
  • Ensure the enclosure is sealed properly (if applicable) and of the correct volume.
  • Adjust crossover frequency and bass boost settings.

If problems persist after performing these checks, contact customer support or a qualified technician.
