Setup and Installation
Proper installation is crucial for the performance and longevity of your subwoofer. It is highly recommended that installation be performed by a qualified car audio professional.
Choosing an Enclosure
The G715D2 subwoofer is designed to be used with a suitable enclosure. The type and size of the enclosure significantly impact the subwoofer's sound characteristics. Common enclosure types include sealed, ported, and bandpass. Consult with a car audio specialist or refer to online resources for recommended enclosure volumes and port tuning frequencies for a 15-inch subwoofer.
For optimal bass, a 12-inch or 15-inch subwoofer is generally recommended if space permits. The advantage of purchasing the bare subwoofer is the flexibility to build or buy a custom enclosure that perfectly fits your vehicle and audio system requirements.
Wiring Configurations (2 Ohm DVC)
The G715D2 features a Dual Voice Coil (DVC) design with 2 Ohm coils, offering versatile wiring options to match your amplifier's impedance requirements.
- 1 Ohm Load: Wire the two 2 Ohm voice coils in parallel. This configuration provides maximum power output from compatible amplifiers.
- 4 Ohm Load: Wire the two 2 Ohm voice coils in series. This configuration is suitable for amplifiers stable at 4 Ohms.
Always ensure your amplifier is stable at the chosen impedance load to prevent damage to both the amplifier and the subwoofer. Refer to your amplifier's manual for its impedance capabilities.
Mounting the Subwoofer
Securely mount the subwoofer into the chosen enclosure using appropriate screws and a tight seal. Ensure no air leaks are present around the mounting flange, as this can negatively affect performance.

Operating Instructions
Once installed, follow these guidelines for optimal operation and sound quality.
Break-in Period
Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its limits. This allows the suspension components (surround and spider) to loosen up and reach their optimal compliance, improving performance and longevity.
Amplifier Gain Setting
Set your amplifier's gain correctly to match the output voltage of your head unit. An improperly set gain can lead to clipping, which can damage the subwoofer. It is recommended to use an oscilloscope or consult a professional for accurate gain setting.
Crossover Settings
Utilize your amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical LPF setting for a subwoofer is between 60Hz and 100Hz. Experiment with settings to find the best blend with your main speakers.
Subsonic Filter
If your amplifier has a subsonic filter, enable it and set it slightly below your ported enclosure's tuning frequency (if applicable) or around 25-30Hz for sealed enclosures. This protects the subwoofer from playing frequencies too low for it to reproduce safely, preventing over-excursion and potential damage.

Maintenance
The Gravity Warzone G715D2 subwoofer requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the cone and surround with a soft, dry cloth to remove dust and debris. Avoid using harsh chemicals or excessive moisture.
- Inspection: Regularly inspect the subwoofer for any signs of damage to the cone, surround, or spider. Check wiring connections for tightness and corrosion.
- Environmental Factors: Protect the subwoofer from extreme temperatures, direct sunlight, and excessive moisture, which can degrade materials over time.
