Once the enclosure is ready, carefully mount the subwoofer using appropriate screws, ensuring a tight, airtight seal between the subwoofer frame and the enclosure baffle.
2. Câblage du caisson de basses
The G712D2 features a Dual Voice Coil (DVC) design with two 2-Ohm voice coils. This allows for flexible wiring configurations to match your ampExigences d'impédance de l'amplificateur. Les configurations courantes comprennent :
- Charge de 1 ohm : Wire the two 2-Ohm voice coils in parallel. This configuration is suitable for amplifiers stable at 1 Ohm.
- Charge de 4 ohm : Wire the two 2-Ohm voice coils in series. This configuration is suitable for amplifiers stable at 4 Ohms.
Référez-vous à votre amplifier's manual to determine its stable impedance ratings. Incorrect wiring can damage both the subwoofer and the amplifier.

Ensure all connections are secure and properly insulated. Use high-quality speaker wire of adequate gauge (e.g., 12-14 gauge for typical installations) to minimize power loss.
Mode d'emploi
1. Connexion à un Amplifier
Connect the wired subwoofer to the subwoofer output terminals of your car audio amplifier. Ensure polarity is correct (+ to + and - to -) to prevent phase issues.
2. Initial Power-Up and Settings
- Before powering on, set your amplifier's gain control to its minimum setting.
- Allumez le système audio de votre voiture.
- Play a familiar audio track with strong bass content.
- Augmentez lentement le amplifier's gain control until you hear clear, undistorted bass. If distortion occurs, reduce the gain immediately.
- Réglez le filtre passe-bas (LPF) de votre amplifier or head unit. A common starting point is between 80Hz and 100Hz. This ensures the subwoofer only reproduces low frequencies.
- Adjust the phase control (if available on your amplifier) to achieve the best blend with your main speakers.
Proper tuning is crucial for sound quality and subwoofer longevity. If you are unsure, consult a professional car audio installer.
