Safety Information
Always disconnect the vehicle's battery before beginning any electrical work. Ensure all wiring is properly insulated and secured to prevent short circuits. Consult a professional car audio installer if you are unsure about any part of the installation process. Operating audio equipment at excessively high volumes can cause permanent hearing damage.
Setup and Installation
1. Unpacking and Inspection
Carefully remove the subwoofer from its packaging. Inspect the unit for any signs of damage during transit. If damage is found, contact your dealer immediately.
2. Choosing an Enclosure
The NA-10D4 is designed to perform optimally in a sealed or ported enclosure. Refer to recommended enclosure specifications from Nemesis Audio for best results. Proper enclosure design is crucial for sound quality and subwoofer longevity.
3. Wiring Configurations (Dual 4-Ohm Voice Coil)
The NA-10D4 features a Dual 4-Ohm Voice Coil (DVC) design, offering flexibility in wiring to achieve different impedance loads for your amplifier. Always ensure your amplifier is stable at the chosen impedance.
- Parallel Wiring (2 Ohms): Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect these combined positive and negative terminals to your amplifier. This configuration presents a 2-ohm load to the amplifier.
- Series Wiring (8 Ohms): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining positive terminal and negative terminal to your amplifier. This configuration presents an 8-ohm load to the amplifier.

4. Mounting the Subwoofer
Ensure the mounting surface is sturdy and free from obstructions. Use appropriate screws to secure the subwoofer to the enclosure. Do not overtighten screws, as this can damage the speaker frame.

Operating Instructions
Once installed, connect your amplifier to the vehicle's head unit and power source according to the amplifier's manual. Ensure all connections are secure before powering on the system.
- Initial Power-Up: Start with the amplifier's gain control at its minimum setting. Gradually increase the volume on your head unit.
- Gain Adjustment: Adjust the amplifier's gain control carefully. The gain setting should match the output voltage of your head unit, not act as a volume control. Incorrect gain settings can lead to distortion and damage to the subwoofer.
- Crossover Settings: Use the low-pass filter (LPF) on your amplifier or head unit to send only low frequencies to the subwoofer. A typical crossover point for a 10-inch subwoofer is between 60Hz and 100Hz, but this can vary based on your system and preferences.
- Break-in Period: Allow a break-in period of approximately 20-30 hours of normal listening before pushing the subwoofer to its limits. This allows the suspension components to loosen up and perform optimally.
Maintenance
The Nemesis Audio NA-10D4 subwoofer requires minimal maintenance. Keep the subwoofer cone and surround free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or solvents. Ensure all wiring connections remain secure over time.
