6. Setup and Installation
Proper installation is crucial for the performance and longevity of your amplifier. Follow these steps carefully:
6.1. Mounting Location
- Choose a dry, well-ventilated location away from direct sunlight or heat sources.
- Ensure sufficient space around the amplifier for air circulation.
- Securely mount the amplifier to a solid surface using appropriate hardware.
6.2. Power and Ground Connections
Before making any connections, disconnect the vehicle's negative battery terminal.
- Power Cable (+12V): Run the 17 ft. red 4GA power cable from the positive terminal of your vehicle's battery to the amplifier's +12V terminal. Install the ANL fuse holder within 18 inches (45 cm) of the battery.
- Ground Cable (GND): Connect the 3 ft. black 4GA ground cable from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote Turn-On (REM): Connect the 17 ft. remote cable from your head unit's remote output to the amplifier's REM terminal. This cable turns the amplifier on and off with your head unit.

6.3. Speaker Connections
- Connect your subwoofer(s) to the amplifier's speaker output terminals using the 17 ft. red/black speaker cable.
- Ensure correct polarity (+ to + and - to -) for optimal sound performance.
- Verify that the total impedance of your subwoofer(s) matches the amplifier's stable impedance range (1, 2, or 4 Ohm).
6.4. Input Connections
- RCA Input: Connect the 17 ft. Red/Black Twisted RCA cable from your head unit's subwoofer or pre-amp output to the amplifier's LINE INPUT (RCA) jacks.
- High Input: If your head unit does not have RCA outputs, use the High Input connection. Consult your head unit's manual for proper wiring to the amplifier's High Input terminal.
6.5. Remote Bass Knob Connection
- Connect the remote bass knob to the amplifier's 'REMOTE' port using the provided cable. Mount the bass knob in a convenient location for easy access.
7. Operating Instructions
Once installed, adjust the amplifier settings for optimal sound performance.

- GAIN: This control matches the amplifier's input sensitivity to the output of your head unit. Start with the gain at minimum (MIN) and slowly increase it until you hear distortion, then back off slightly.
- BASS BOOST: Adjusts the level of bass enhancement (0dB to +12dB). Use sparingly to avoid distortion.
- BOOST FREQ: Selects the center frequency for the bass boost (40Hz to 100Hz).
- LPF (Low Pass Filter): Sets the upper frequency limit for the amplifier's output (50Hz to 150Hz). This ensures only low frequencies are sent to your subwoofer.
- PHASE: Adjusts the phase of the subwoofer output (0° or 180°). This helps to align the subwoofer's output with other speakers in your system for better sound integration.
- REMOTE (Bass Knob): Use the external remote bass knob to conveniently adjust the subwoofer output level from your listening position.
8. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your amplifier:
- Cleaning: Periodically wipe the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure that the amplifier's cooling fins are free from dust and debris to maintain proper airflow.
- Connections: Periodically check all power, ground, remote, and speaker connections to ensure they remain secure and free from corrosion.
- Fuses: If the amplifier does not power on, check the external ANL fuse and the internal fuses (3 x 35A). Replace blown fuses only with fuses of the same type and rating.
9. Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Amplifier does not turn on | Blown fuse (external or internal) Poor power or ground connection No remote turn-on signal | Check and replace fuses. Verify all power and ground connections are secure. Check remote wire connection and head unit's remote output. |
| No sound output | RCA cables disconnected or faulty Speaker wires disconnected or shorted Gain set too low Head unit volume too low | Check RCA connections. Inspect speaker wiring for shorts or disconnections. Increase gain setting gradually. Increase head unit volume. |
| Distorted sound | Gain set too high Speaker impedance mismatch Poor ground connection | Reduce gain setting. Verify speaker impedance is within amplifier's stable range. Ensure ground connection is clean and secure. |
| Amplifier overheats | Insufficient ventilation Speaker impedance too low Playing at high volume for extended periods | Relocate amplifier to a better ventilated area. Check speaker impedance. Reduce volume or allow amplifier to cool down. |
