2. Setup and Installation
2.1 Unpacking
Carefully remove the subwoofer from its packaging. Inspect the unit for any signs of damage that may have occurred during shipping. If any damage is found, contact your retailer immediately.
2.2 Recommended Enclosure
For optimal performance, it is highly recommended to install this subwoofer in a properly designed and constructed sealed or ported enclosure. Consult a professional car audio installer or refer to specialized audio resources for appropriate enclosure volume and port tuning for a 15-inch subwoofer.
2.3 Wiring Connections
The Gravity Warzone subwoofer features a Dual Voice Coil (DVC) design with 4 Ohm impedance per voice coil. Proper wiring is crucial for optimal performance and to prevent damage to the subwoofer or amplifier. Ensure your amplifier is stable at the chosen impedance.
Figure 2: Close-up view of the subwoofer's dual voice coil terminals, showing the positive and negative connections for each coil.
Parallel Wiring (2 Ohm Load): Connect the positive (+) terminal of voice coil 1 to the positive (+) terminal of voice coil 2. Connect the negative (-) terminal of voice coil 1 to the negative (-) terminal of voice coil 2. Then, connect the amplifier's positive output to the combined positive terminals and the amplifier's negative output to the combined negative terminals. This configuration results in a 2 Ohm load.
Series Wiring (8 Ohm Load): Connect the positive (+) terminal of voice coil 1 to the amplifier's positive output. Connect the negative (-) terminal of voice coil 1 to the positive (+) terminal of voice coil 2. Connect the negative (-) terminal of voice coil 2 to the amplifier's negative output. This configuration results in an 8 Ohm load.
Always ensure all connections are secure and free from short circuits. Use appropriate gauge wiring for power and speaker connections.
3. Operating Guidelines
3.1 Break-in Period
Allow a break-in period of approximately 20-30 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components (surround and spider) to loosen up, improving performance and longevity.
3.2 Amplifier Matching
This subwoofer has a peak power handling of 3500 Watts. Ensure your amplifier's RMS power output is appropriately matched to the subwoofer's RMS power handling to prevent underpowering or overpowering, both of which can cause damage. Underpowering can be as damaging as overpowering due to amplifier clipping.
3.3 Crossover Settings
Utilize your amplifier's or head unit's low-pass filter (LPF) to send only low frequencies to the subwoofer. A typical LPF setting for this subwoofer would be between 80Hz and 120Hz, depending on your full-range speakers and personal preference. Avoid sending full-range audio signals to the subwoofer.
4. Maintenance
The Gravity Warzone subwoofer requires minimal maintenance. Keep the cone and surround free from dust and debris. Periodically check all wiring connections to ensure they remain secure. Avoid exposing the subwoofer to excessive moisture or extreme temperatures, as it is not waterproof.
