Setup and Installation
Proper installation is crucial for optimal performance and longevity of your subwoofer. It is recommended that installation be performed by a qualified car audio professional.
Mounting Considerations
- Ensure the mounting location (e.g., subwoofer enclosure) is robust and provides adequate air volume for the subwoofer's size.
- The subwoofer is designed for flush mounting. Ensure the cutout diameter matches the subwoofer's specifications.
- Allow sufficient clearance behind the subwoofer for proper ventilation and to prevent obstruction of the magnet structure.

Wiring the Dual Voice Coil (DVC) Subwoofer
The G5 subwoofer features a 4 Ohm DVC, offering flexibility in wiring to achieve different impedance loads for your amplifier. Always consult your amplifier's manual for compatible impedance loads.
- Parallel Wiring (2 Ohm Load): Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect these combined positive and negative terminals to the amplifier. This configuration results in a 2 Ohm load.
- Series Wiring (8 Ohm Load): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining positive and negative terminals to the amplifier. This configuration results in an 8 Ohm load.
Ensure all connections are secure and properly insulated to prevent short circuits. Use appropriate gauge wiring for power and speaker connections.

Operating Instructions
Once installed, follow these guidelines for optimal operation:
- Break-in Period: Allow a break-in period of approximately 20-30 hours of moderate listening before operating the subwoofer at high volumes. This allows the suspension components to loosen up and perform optimally.
- Gain Setting: Properly set the gain on your amplifier to match the output voltage of your head unit. Avoid setting the gain too high, as this can lead to clipping and damage to the subwoofer.
- Crossover Settings: Use a low-pass filter (LPF) on your amplifier or head unit to ensure only low frequencies are sent to the subwoofer. A typical LPF setting for a 12-inch subwoofer might be between 60Hz and 100Hz.
- Subsonic Filter: If your amplifier has a subsonic filter, enable it and set it slightly below your enclosure's tuning frequency to protect the subwoofer from over-excursion at very low frequencies.
- Listen for Distortion: If you hear any distortion, rattling, or unpleasant sounds, immediately reduce the volume. Continued operation with distortion can cause permanent damage.
Maintenance
The Gravity G5 subwoofer requires minimal maintenance to ensure long-term performance:
- Cleaning: Use a soft, dry cloth to wipe down the cone and surround. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect the subwoofer for any signs of damage to the cone, surround, or dust cap. Check wiring connections for tightness and corrosion.
- Environmental Factors: Protect the subwoofer from extreme temperatures, direct sunlight, and moisture.
