2. Key Features
- Compact Design: Features a low-profile chassis and small footprint for installation in vehicles with limited space.
- Variable Electronic Crossovers and Bass Boost: Allows for precise system tuning and optimized subwoofer performance.
- Balanced Differential Inputs: Engineered to ensure low noise and distortion, even at high output levels, and reduces susceptibility to line-induced engine noise.
- On-board Protection Circuitry: Protects the amplifier from shorts, high-temperature, overvoltage, and undervoltage conditions. An LED indicator signals when these conditions occur.
- RBC Wired Remote: Provides convenient volume adjustment for the subwoofer from the driver's seat.
- High and Low-Level Inputs: Compatible with both aftermarket and factory car stereo systems.
3. Setup and Installation
Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by a qualified professional.
3.1 Mounting the Amplifier
Select a mounting location that is dry, well-ventilated, and secure. The compact size of the Reference-6001A allows for flexible placement in various vehicles. Ensure adequate airflow around the amplifier to prevent overheating.
3.2 Wiring Connections
Refer to the diagram below for typical wiring connections. Always disconnect the vehicle's battery before making any power connections.

- Power (+12V): Connect to the positive terminal of the vehicle's battery using a fuse-protected power cable.
- Ground (GND): Connect to a clean, unpainted metal surface of the vehicle chassis.
- Remote (REM): Connect to the remote turn-on output of your head unit.
- Speaker Output (SUB): Connect your subwoofer(s) to these terminals. Ensure correct polarity.
- Input (RCA or Speaker Level): Use RCA cables for low-level inputs from an aftermarket head unit or speaker-level inputs for factory radios.
- Remote Control (RBC): Connect the wired remote bass knob to the designated port for convenient bass level adjustment.
4. Operating the Amplifier
Once installed, adjust the amplifier settings to match your audio system and personal preferences.
4.1 Gain Adjustment
Set the gain control to match the output voltage of your head unit. Start with the gain at minimum and slowly increase it until the desired volume is achieved without distortion.
4.2 Low-Pass Filter (LPF)
The LPF controls the upper frequency limit of the audio signal sent to the subwoofer. Adjust this to blend the subwoofer's output seamlessly with your full-range speakers.
4.3 Bass Boost
The variable bass boost allows you to increase the bass output at a specific frequency. Use this sparingly to avoid distortion and potential damage to your subwoofer.
4.4 Phase Switch
The phase switch (0°/180°) helps ensure that the subwoofer's output is in phase with the rest of your speakers, providing a more cohesive and impactful bass response.
4.5 RBC Wired Remote
Use the wired remote to conveniently adjust the subwoofer's output level from your driving position.
5. Maintenance
The Infinity Reference-6001A amplifier requires minimal maintenance. Keep the unit clean and free from dust and debris. Periodically check all wiring connections to ensure they are secure and free from corrosion. Do not use harsh chemicals or abrasive cleaners.
6. Troubleshooting
If you experience issues with your amplifier, consult the following guide before seeking professional service.
6.1 Protection LED Indicator
The amplifier features an LED indicator that illuminates when the on-board protection circuitry is activated due to shorts, high temperature, overvoltage, or undervoltage. If the LED is lit, check the following:
- Short Circuit: Inspect speaker wiring for any shorts to ground or between positive and negative terminals.
- Overheating: Ensure the amplifier has adequate ventilation. Allow the unit to cool down.
- Voltage Issues: Verify the vehicle's battery voltage is within the operating range (typically 11V-16V).
6.2 Common Issues
- No Power: Check the main fuse, power cable connection, ground connection, and remote turn-on wire.
- No Sound: Verify input signal connections (RCA or speaker level), speaker connections, and amplifier gain settings. Check head unit output.
- Distorted Sound: Reduce gain setting, check speaker impedance, and ensure bass boost is not set too high.
