Setup and Installation
Proper installation is crucial for the performance and safety of your subwoofer. It is highly recommended that installation be performed by a qualified car audio professional. Incorrect wiring or enclosure design can lead to poor sound quality or damage to the subwoofer and your vehicle's electrical system.
Choosing an Enclosure
The type and size of the enclosure significantly impact the subwoofer's performance. Common enclosure types include sealed, ported (vented), and bandpass. Each offers different acoustic characteristics. For optimal performance, consult with a car audio specialist or refer to general subwoofer enclosure guidelines for 15-inch subwoofers. Ensure the enclosure is robust and properly sealed to prevent air leaks.
Wiring the Subwoofer
This subwoofer features a Dual Voice Coil (DVC) configuration, allowing for flexible wiring options (e.g., 2-Ohm or 8-Ohm configurations). Always match the subwoofer's impedance to your amplifier's stable impedance rating. Refer to your amplifier's manual for compatible impedance loads. Use high-quality speaker wire of appropriate gauge for power handling and distance.
- Power Connection: Connect the positive (+) terminal of the subwoofer to the positive (+) output of your amplifier and the negative (-) terminal to the negative (-) output.
- Dual Voice Coil Wiring: Depending on your desired impedance, you can wire the voice coils in series or parallel. Consult wiring diagrams for DVC subwoofers to ensure correct configuration.
- Secure Connections: Ensure all connections are tight and secure to prevent signal loss or short circuits. The spring-loaded speaker terminals are designed for reliable contact.
Mounting
Mount the subwoofer securely within its enclosure using appropriate screws. Ensure the mounting surface is flat and free of obstructions. Avoid overtightening screws, which can damage the speaker frame.

Operating Instructions
Once properly installed, operating your subwoofer involves adjusting your amplifier and head unit settings to achieve the desired bass response.
- Gain Setting: Adjust the gain on your amplifier to match the output voltage of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly.
- Low-Pass Filter (LPF): Set the LPF on your amplifier or head unit to filter out high frequencies from reaching the subwoofer. A common range is 80Hz-120Hz, but this can vary based on your other speakers and personal preference.
- Subsonic Filter: If your amplifier has a subsonic filter, set it to protect the subwoofer from playing frequencies below its resonant frequency, which can cause damage.
- Bass Boost: Use bass boost sparingly, if at all. Excessive bass boost can lead to distortion and potential damage to the subwoofer.
- Volume Control: Always turn down the volume on your head unit before turning off your car or amplifier to prevent sudden loud noises.
Maintenance
To ensure the longevity and optimal performance of your Gravity subwoofer, follow these simple maintenance guidelines:
- Regular Cleaning: Keep the subwoofer cone and surround free from dust and debris. Use a soft, dry cloth to gently wipe the surfaces. Avoid using harsh chemicals or excessive moisture.
- Inspect Connections: Periodically check all wiring connections to ensure they remain secure and free from corrosion. Loose connections can lead to poor performance or damage.
- Avoid Overpowering: Do not continuously operate the subwoofer at maximum volume or with excessive bass boost, as this can lead to overheating and damage to the voice coils. Listen for signs of distortion and reduce volume if heard.
- Proper Enclosure: Ensure the subwoofer enclosure remains intact and sealed. Any cracks or leaks can negatively affect sound quality and potentially damage the subwoofer.
- Temperature Control: While designed for car environments, extreme temperatures can affect performance. Avoid prolonged exposure to direct sunlight or extreme cold when possible.
