4. Installation and Setup

Proper installation is crucial for the performance and longevity of your amplifier. Follow these steps carefully:

4.1 Mounting the Amplifier

• Choose a mounting location that is dry, well-ventilated, and protected from direct sunlight and excessive heat.
• Ensure sufficient airflow around the amplifier's heatsink fins.
• Secure the amplifier firmly to a solid surface using appropriate screws.

4.2 Wiring Connections

Refer to the diagrams below for correct wiring. Always use high-quality wiring and connectors.

Power Connections

• +12V (Power): Connect to the positive terminal of the vehicle's battery. Use a fuse holder with an appropriate fuse (not included) within 18 inches of the battery.
• REM (Remote Turn-On): Connect to the remote turn-on lead from your head unit. This wire turns the amplifier on and off with your car's audio system.
• GND (Ground): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid, low-resistance connection.

Speaker Output Connections

• Connect your subwoofer(s) to the "SPEAKER OUTPUT" terminals. Ensure correct polarity (+ to + and - to -).
• This is a mono amplifier, designed for a single subwoofer or multiple subwoofers wired to a compatible impedance. Refer to your subwoofer's specifications for impedance matching.

Audio Input Connections

• INPUT (RCA): Connect the RCA output cables from your head unit to the amplifier's RCA input jacks.

5. Operating Instructions

Once all connections are made and verified, you can power on your audio system. The amplifier will turn on automatically with your head unit via the remote turn-on wire.

5.1 Initial Power-Up

• Turn on your head unit. The amplifier's power indicator should illuminate.
• Start with all amplifier controls (Gain, LPF, Subsonic, Bass Boost) at their minimum or "OFF" positions.
• Gradually increase the head unit's volume to a moderate level.
• Slowly increase the amplifier's GAIN control until the desired volume is achieved without distortion.

6. Controls and Adjustments

The NA-C1500.1D amplifier features several controls to fine-tune your audio output:

• GAIN (Input Level): Adjusts the input sensitivity of the amplifier to match the output of your head unit. Set this to the lowest possible setting that achieves maximum clean output.
• LPF (Low Pass Filter): This control allows only frequencies below the set point to pass through to the subwoofer. Adjustable from 40Hz to 180Hz. Typically set between 80Hz and 120Hz for subwoofers.
• SUBSONIC: Filters out extremely low frequencies that are inaudible and can damage subwoofers. Adjustable from OFF to 50Hz. Set this slightly below your subwoofer's port tuning frequency or around 20-30Hz for sealed enclosures.
• BASS BOOST: Provides an adjustable bass enhancement from 0 to 12dB. Use sparingly to avoid distortion and potential speaker damage.

7. Maintenance

Your Nemesis Audio amplifier requires minimal maintenance to ensure long-term performance:

• Keep the amplifier clean and free of dust. Use a soft, dry cloth for cleaning.
• Ensure that the heatsink fins are not obstructed to allow for proper cooling.
• Periodically check all wiring connections for tightness and corrosion.
• Avoid exposing the amplifier to extreme temperatures or moisture.
