3.3 Wiring the Dual 4-Ohm Voice Coils
The NA-10SLM V.2 D4 features dual 4-ohm voice coils, offering flexibility in wiring configurations to match your amplifier's impedance requirements. Common configurations include:
- 1-Ohm Load: Wire the two 4-ohm voice coils in parallel. This configuration is suitable for amplifiers stable at 1 ohm.

3.4 Mounting
Ensure the mounting surface is sturdy and free from obstructions. The mounting diameter required is 9.84 inches. Secure the subwoofer firmly using appropriate hardware to prevent movement during vehicle operation.
4. Operating Instructions
4.1 Break-in Period
Allow a break-in period of approximately 10-20 hours of normal listening before operating the subwoofer at high volumes. This allows the suspension components to loosen and reach their optimal performance characteristics.
4.2 Amplifier Settings
Properly set your amplifier's gain, crossover, and bass boost settings. Start with the gain at minimum and slowly increase it until the desired volume is achieved without distortion. Set the low-pass filter (LPF) to prevent higher frequencies from reaching the subwoofer, typically between 60Hz and 100Hz. Avoid excessive bass boost, as this can lead to clipping and damage.
4.3 Listening Levels
While the subwoofer is designed for high power handling, continuous operation at extreme volumes or with distorted signals can cause damage. Listen responsibly and adjust levels to avoid audible distortion.
5. Maintenance
The Nemesis Audio NA-10SLM V.2 D4 subwoofer requires minimal maintenance.
- Cleaning: Use a soft, dry cloth to wipe down the subwoofer cone and frame. Avoid using harsh chemicals or excessive moisture.
- Inspection: Periodically check all wiring connections to ensure they are secure and free from corrosion. Inspect the subwoofer cone and surround for any signs of damage.
- Environment: Ensure the subwoofer is installed in a dry environment, as it is not water-resistant.
