Setup and Installation
Proper installation is crucial for the performance and safety of your subwoofers. It is recommended to have a professional install your car audio system if you are unfamiliar with the process.
Wiring Configurations for Two 4 Ohm DVC Subwoofers
Your Gravity subwoofers feature Dual Voice Coils (DVC) with a 4 Ohm impedance per coil. When wiring two of these subwoofers, several configurations are possible to achieve different final impedances. Always ensure your amplifier is stable at the final impedance load.
1. Series Wiring (8 Ohm Final Impedance per Subwoofer)
For each individual subwoofer, connect the positive terminal of one voice coil to the negative terminal of the other voice coil. This will result in an 8 Ohm impedance for each subwoofer. This configuration is generally safer for amplifiers but delivers less power.
To achieve a final 4 Ohm load for the pair (if wiring the two 8 Ohm subs in parallel):
- For each subwoofer: Connect the positive terminal of Voice Coil 1 to the negative terminal of Voice Coil 2.
- Connect the remaining positive terminal of Subwoofer 1 to the positive terminal of Subwoofer 2.
- Connect the remaining negative terminal of Subwoofer 1 to the negative terminal of Subwoofer 2.
- Connect the amplifier's positive output to the combined positive terminals, and the amplifier's negative output to the combined negative terminals.
This results in a final impedance of 4 Ohms for the pair.
2. Parallel Wiring (2 Ohm Final Impedance per Subwoofer)
For each individual subwoofer, connect the positive terminals of both voice coils together, and connect the negative terminals of both voice coils together. This will result in a 2 Ohm impedance for each subwoofer. This configuration draws more power from the amplifier.
To achieve a final 1 Ohm load for the pair (if wiring the two 2 Ohm subs in parallel):
- For each subwoofer: Connect the positive terminal of Voice Coil 1 to the positive terminal of Voice Coil 2.
- For each subwoofer: Connect the negative terminal of Voice Coil 1 to the negative terminal of Voice Coil 2.
- Connect the amplifier's positive output to the combined positive terminals of Subwoofer 1 and Subwoofer 2.
- Connect the amplifier's negative output to the combined negative terminals of Subwoofer 1 and Subwoofer 2.
This results in a final impedance of 1 Ohm for the pair. Ensure your amplifier is 1 Ohm stable.
Visual Aids for Wiring
The following videos provide visual guidance on subwoofer wiring techniques. While the specific impedance or number of subwoofers in the videos may vary, the fundamental principles of connecting voice coils and subwoofers remain applicable.
Wiring Configuration for 1 DVC 4 Ohm Subwoofer
Video: Demonstrates wiring configurations for a single Dual Voice Coil (DVC) 4 Ohm subwoofer. This is directly applicable to wiring one of your Gravity subwoofers.
Wiring Configuration for 2 DVC 1 Ohm Subwoofers
Video: Illustrates wiring configurations for two Dual Voice Coil (DVC) 1 Ohm subwoofers. While the impedance differs from your product, the techniques for connecting multiple DVC subwoofers can be adapted.
Enclosure and Mounting
Ensure your subwoofer is mounted securely in an appropriate enclosure. The enclosure should be designed to match the subwoofer's specifications for optimal sound quality and to prevent damage. Refer to the subwoofer's technical specifications for recommended enclosure volumes and port tuning frequencies.

Operating Instructions
Once installed, ensure your amplifier settings (gain, crossover, bass boost) are properly adjusted to prevent damage to the subwoofers and achieve desired sound quality. Start with low gain settings and gradually increase them while listening for distortion.
- Break-in Period: Allow a break-in period of approximately 10-20 hours of moderate listening before operating the subwoofers at high volumes. This allows the suspension components to loosen up and perform optimally.
- Crossover Settings: Set your low-pass filter (LPF) on your amplifier or head unit to prevent high frequencies from reaching the subwoofer, typically between 80Hz and 120Hz.
- Gain Adjustment: Adjust the amplifier gain to match the output voltage of your head unit. Avoid setting the gain too high, as this can lead to clipping and damage.
- Bass Boost: Use bass boost sparingly, if at all. Excessive bass boost can cause distortion and damage.
Maintenance
Regular maintenance ensures the longevity and performance of your subwoofers.
- Cleaning: Keep the subwoofer cones and surrounds free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals.
- Inspection: Periodically inspect the wiring connections for any signs of corrosion or looseness. Ensure all mounting screws are tight.
- Avoid Overpowering: Do not continuously operate the subwoofers at levels that cause audible distortion. This can lead to voice coil overheating and failure.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound from Subwoofer | No power to amplifier, loose wiring, amplifier in protect mode, incorrect head unit settings. | Check power and ground connections to amplifier. Verify all speaker wires are securely connected. Check amplifier fuses. Ensure head unit is sending signal. |
| Distorted Sound | Amplifier gain too high, incorrect crossover settings, damaged subwoofer. | Reduce amplifier gain. Adjust LPF settings. Inspect subwoofer for physical damage. |
| Subwoofer Overheating | Impedance mismatch, overpowering, insufficient ventilation. | Verify correct wiring impedance for your amplifier. Reduce volume/gain. Ensure amplifier has adequate airflow. |
