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 professional car audio installer.
Enclosure Requirements
The VXF-12 D2 requires a robust, properly sized enclosure for optimal performance. Consult Skar Audio's recommended enclosure specifications for sealed or ported designs. An improperly designed enclosure can lead to poor sound quality and potential damage to the subwoofer.
Wiring Configurations (Dual 2 Ohm)
The VXF-12 D2 features dual 2-ohm voice coils, offering flexibility in wiring to achieve different final impedances. Always match the final impedance to your amplifier's stable operating impedance.
- 1 Ohm Load (Parallel Wiring): 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 combined positive to the amplifier's positive output and the combined negative to the amplifier's negative output. This configuration is suitable for amplifiers stable at 1 ohm.
- 4 Ohm Load (Series Wiring): Connect the positive terminal of Voice Coil 1 to the negative terminal of Voice Coil 2. The remaining negative terminal of Voice Coil 1 becomes the subwoofer's negative input, and the remaining positive terminal of Voice Coil 2 becomes the subwoofer's positive input. Connect these to your amplifier. This configuration is suitable for amplifiers stable at 4 ohms.
Refer to your amplifier's manual for its stable impedance ratings. Incorrect wiring can damage both the subwoofer and the amplifier.
Power and Ground Connections
Ensure all power and ground wiring uses appropriate gauge wire for the power levels involved. A dedicated power wire from the vehicle's battery with an inline fuse is essential. The ground wire should be short and securely fastened to a clean, unpainted metal surface of the vehicle chassis.

Operating Instructions
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 and reach their optimal compliance, improving performance and longevity.
Amplifier Gain Setting
Properly setting your amplifier's gain is critical. The gain control is not a volume knob; it matches the amplifier's input sensitivity to the output voltage of your head unit. Setting the gain too high can lead to clipping, which causes distortion and can severely damage your subwoofer. It is recommended to use an oscilloscope or consult a professional for accurate gain setting.
Crossover and Subsonic Filter Settings
Utilize your amplifier's or head unit's low-pass filter (LPF) to ensure the subwoofer only reproduces frequencies it is designed for (typically below 80-100 Hz). A subsonic filter (HPF) is also highly recommended to protect the subwoofer from playing frequencies below its resonant frequency (Fs: 32.1 Hz), which can cause excessive excursion and damage.
Maintenance
The Skar Audio VXF-12 D2 subwoofer requires minimal maintenance. Keep the cone and surround free from dust and debris. Avoid exposing the subwoofer to extreme temperatures or moisture. Periodically check all wiring connections to ensure they are secure and free from corrosion.
