5. Installation (Setup)
Proper installation is crucial for optimal performance and longevity of your subwoofer. If you are unsure about any step, consult a professional car audio installer.
5.1 Pre-Installation Checks
- Ensure the vehicle's electrical system can support the power requirements of the subwoofer and amplifier.
- Verify that the enclosure (if used) is appropriately sized and constructed for an 8-inch subwoofer.
- Gather all necessary tools and wiring materials.
5.2 Mounting the Subwoofer
- Carefully place the subwoofer into the designated mounting hole in the enclosure.
- Align the mounting holes on the subwoofer frame with the holes in the enclosure.
- Secure the subwoofer using appropriate screws, ensuring even pressure around the frame. Do not overtighten.
5.3 Wiring the Dual Voice Coil (DVC) Subwoofer
The Gravity Warzone subwoofer features a Dual Voice Coil (DVC) design, offering wiring flexibility. Each voice coil has an impedance of 4 Ohms. You can wire the voice coils in series or parallel to achieve different final impedances at the amplifier.
5.3.1 Parallel Wiring (2 Ohms Total Impedance)
Connect the positive terminal of Voice Coil 1 to the positive terminal of Voice Coil 2. Connect the negative terminal of Voice Coil 1 to the negative terminal of Voice Coil 2. Then, connect the combined positive to the amplifier's positive output and the combined negative to the amplifier's negative output. This configuration results in a 2 Ohm load.
5.3.2 Series Wiring (8 Ohms Total Impedance)
Connect the positive terminal of Voice Coil 1 to the amplifier's positive output. Connect the negative terminal of Voice Coil 1 to the positive terminal of Voice Coil 2. Connect the negative terminal of Voice Coil 2 to the amplifier's negative output. This configuration results in an 8 Ohm load.

5.4 Connecting to the Amplifier
- Ensure the amplifier is powered off.
- Connect the subwoofer's wired output (from your chosen DVC configuration) to the appropriate speaker output terminals on your amplifier.
- Double-check all connections for polarity and security.
6. Operation
6.1 Initial Power-Up and Settings
- After installation, reconnect the vehicle's negative battery terminal.
- Turn on your car audio system with the volume set to minimum.
- Gradually increase the volume and adjust the amplifier's gain, crossover, and bass boost settings according to your preferences and the amplifier's recommendations. Start with low gain and a low-pass filter (LPF) setting appropriate for a subwoofer (e.g., 80-120 Hz).
6.2 Break-In Period
Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at maximum output. This allows the suspension components to loosen and achieve optimal performance.
7. Maintenance
The Gravity Warzone subwoofer requires minimal maintenance. Follow these guidelines to ensure its longevity:
- Cleaning: Use a soft, dry cloth to wipe down the subwoofer cone and surround. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically check all wiring connections for tightness and signs of corrosion. Inspect the subwoofer cone and surround for any tears or damage.
- Environment: Keep the subwoofer in a dry environment, away from direct sunlight and extreme temperatures.
