5. Setup & Installation
Proper installation is crucial for optimal performance and longevity of your subwoofer. Consult a professional if you are unsure about any steps.
5.1. Enclosure Requirements
The ZVX-15v2 D2 subwoofer requires a properly designed enclosure for optimal performance. Refer to the specifications section for recommended enclosure volumes and tuning frequencies. An improperly sized or constructed enclosure can lead to poor sound quality and potential damage to the subwoofer.
5.2. Wiring Configurations (Dual 2 Ohm)
The ZVX-15v2 D2 features dual 2-ohm voice coils, offering flexible wiring options to match your amplifier's impedance requirements. Always ensure your amplifier is stable at the chosen impedance.
- 1 Ohm Parallel Wiring: Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect the combined positive to the amplifier's positive output and the combined negative to the amplifier's negative output. This results in a 1-ohm load.
- 4 Ohm Series Wiring: Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining positive terminal to the amplifier's positive output and the remaining negative terminal to the amplifier's negative output. This results in a 4-ohm load.
Consult your amplifier's manual to determine its stable impedance range before wiring.
5.3. Mounting
Ensure the subwoofer is securely mounted in its enclosure. Use appropriate screws and ensure a tight seal to prevent air leaks, which can degrade performance. The mounting type is designed for car installations.

6. Operating Instructions
Once installed, follow these guidelines for optimal performance and longevity:
- 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 to loosen up and perform optimally.
- Gain Setting: Properly set your amplifier's gain 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 send only low frequencies to the subwoofer. A common starting point is 80-100 Hz.
- Subsonic Filter: Utilize a subsonic filter (HPF) to protect the subwoofer from playing frequencies below its resonant frequency (Fs). For this model, with an Fs of 39.0 Hz, a subsonic filter set around 30-35 Hz is recommended.
- Volume Control: Listen for signs of distortion. If you hear distortion, reduce the volume immediately to prevent damage.
7. Maintenance
Regular maintenance ensures your subwoofer continues to perform reliably:
- Cleaning: Keep the subwoofer cone and surround free of dust and debris. Use a soft, dry cloth for cleaning.
- Inspection: Periodically inspect the wiring connections for tightness and corrosion. Check the surround for any tears or damage.
- Environment: Ensure the subwoofer is not exposed to direct sunlight for extended periods or extreme temperature fluctuations.
8. Troubleshooting
If you experience issues with your subwoofer, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Sound | No power to amplifier; loose wiring; amplifier in protect mode; blown fuse. | Check power connections, fuses, and amplifier status. Verify all wiring is secure. |
| Distorted Sound | Amplifier gain too high; improper crossover settings; damaged voice coil. | Reduce amplifier gain. Adjust crossover settings. If distortion persists at low volumes, the subwoofer may be damaged. |
| Weak Bass | Incorrect wiring impedance; improper enclosure; phase issue; low amplifier power. | Verify wiring impedance matches amplifier. Check enclosure for leaks. Ensure subwoofer phase is correct. Consider a more powerful amplifier. |
| Subwoofer Overheating | Overpowering; improper enclosure; insufficient cooling. | Reduce power. Ensure enclosure is correctly sized and vented. Check for adequate airflow around the subwoofer. |
