Product Features
- 8-inch Flat Design: Slim profile for installation in compact spaces without compromising performance.
- 3000W Peak / 600W RMS Power: Delivers powerful and controlled low-end frequencies for accurate bass output.
- Dual Voice Coil (DVC): Offers flexible wiring options for 2Ω or 4Ω configurations, allowing compatibility with various amplifiers.
- High-Grade Construction: Features a durable steel basket and a vented magnet structure for enhanced longevity and heat dissipation.
- Optimized for Small Enclosures: Designed for efficient performance in shallow mounting applications, under-seat installations, or custom enclosures.
Setup and Installation
Proper installation is crucial for the performance and longevity of your subwoofer. If you are unsure about any steps, consult a professional car audio installer.
Mounting Considerations
- The TG-F80D is designed for shallow mounting. Choose a location that provides adequate clearance and structural integrity.
- Ensure the enclosure is sealed and properly braced to prevent rattles and optimize bass response.
- Refer to your amplifier's manual for recommended enclosure volumes and tuning frequencies.
Wiring the Dual Voice Coil (DVC)
The Dual Voice Coil design allows for flexible wiring configurations to match your amplifier's impedance requirements.
- Parallel Wiring (1Ω or 2Ω total impedance): Connect positive terminals of both voice coils together, and negative terminals of both voice coils together. Then connect to the amplifier.
- Series Wiring (4Ω or 8Ω total impedance): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. The remaining positive and negative terminals connect to the amplifier.
Consult your amplifier's specifications to determine the optimal impedance load.

Operating Instructions
Initial Power-Up
- After installation, double-check all wiring connections.
- Turn on your car audio system and set the amplifier gain to its lowest setting.
- Gradually increase the volume and adjust the amplifier gain and crossover settings to achieve balanced sound without distortion.
Break-in Period
Allow a break-in period of approximately 10-20 hours of moderate listening before operating the subwoofer at high volumes. This allows the suspension components to loosen and perform optimally.
Optimal Performance
- Avoid overdriving the subwoofer. If you hear distortion, reduce the volume or amplifier gain.
- Ensure your amplifier provides sufficient power (RMS) to match the subwoofer's capabilities (600W RMS).
Maintenance
- Periodically inspect all wiring connections for tightness and corrosion.
- Keep the subwoofer cone free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid applying excessive pressure to the subwoofer cone or surround.
Troubleshooting
No Sound from Subwoofer
- Check all power and ground connections to the amplifier and subwoofer.
- Verify the remote turn-on wire is connected and receiving power.
- Ensure RCA cables are securely connected to both the head unit and amplifier.
- Check amplifier fuses and the vehicle's main fuse.
- Confirm amplifier is powered on (indicator light).
Distorted Sound
- Reduce amplifier gain. Gain should be set to match the head unit's output, not to maximize volume.
- Check for proper crossover settings. The subwoofer should only reproduce low frequencies.
- Ensure the enclosure is sealed and free from air leaks.
- Verify the subwoofer is not overdriven. Reduce volume.
Subwoofer Overheating
- Check amplifier impedance load. Ensure it matches the subwoofer's wiring configuration.
- Ensure adequate ventilation around the amplifier.
- Avoid prolonged operation at maximum volume.
