Setup and Installation
Proper installation is crucial for optimal performance and safety. Follow these steps carefully.
Mounting the Amplifier:
Choose a secure, dry location with sufficient airflow. Avoid mounting on carpet or in enclosed spaces without ventilation. Ensure the mounting surface is strong enough to support the amplifier's weight.
Wiring Connections:
Refer to the diagrams below for proper wiring. Always use high-quality wiring and connectors.

Power, Ground, and Remote Connections:
- +12V (Power): Connect to the positive terminal of the vehicle's battery using a fuse holder within 18 inches of the battery. Use appropriate gauge wire (e.g., 4-gauge for this amplifier).
- GND (Ground): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid connection for optimal performance and safety.
- REM (Remote): Connect to the remote turn-on lead from your head unit. This wire turns the amplifier on and off with your stereo.
RCA Input Connections:

- Connect RCA cables from your head unit's pre-amp outputs to the amplifier's RCA inputs (CH1, CH2, CH3, CH4).
- For 4-channel operation, connect all four RCA inputs.
- For 2-channel input to drive 4 channels, use the input selection switch (CONFIG) on the amplifier.
Speaker Connections:
- Connect your speakers to the amplifier's speaker terminals. Ensure correct polarity (+ to + and - to -).
- The REA600.4 supports stereo operation (4 channels) or bridged operation (2 channels).
- For bridged mode, connect speakers across the designated bridged terminals (e.g., CH1+ and CH2- for one bridged channel). Refer to the amplifier's terminal markings.
- Ensure the speaker impedance matches the amplifier's capabilities (2-3 Ohm stable for stereo, 4 Ohm stable for bridged).
Operating Instructions
Once installed, adjust the amplifier settings for optimal sound quality.

Adjusting Controls:
- Gain: Adjust the gain control to match the output voltage of your head unit. Start with the gain at minimum and slowly increase until the desired volume is achieved without distortion.
- HPF (High Pass Filter): Filters out low frequencies, typically used for full-range speakers to prevent them from playing bass notes they cannot reproduce effectively. Adjustable from 15Hz - 350Hz.
- LPF (Low Pass Filter): Filters out high frequencies, typically used for subwoofers to ensure they only play bass notes. Adjustable from 35Hz - 350Hz.
- Crossover Selection (X-OVER): Select between Full, HPF, or LPF modes for each channel pair.
- Bass Boost: Provides an adjustable bass enhancement (0 - 12dB). Use sparingly to avoid distortion.
- Input Selection (CONFIG): Switch between 2CH and 4CH input modes depending on your head unit's RCA outputs.
Maintenance
To ensure the longevity and performance of your amplifier, follow these simple maintenance guidelines:
- Keep the amplifier clean and free of dust and debris. Use a soft, dry cloth for cleaning.
- Ensure proper ventilation around the amplifier at all times. Do not block the heatsink fins.
- Periodically check all wiring connections for tightness and corrosion.
- Avoid exposing the amplifier to extreme temperatures or moisture.
Troubleshooting
If you experience issues with your amplifier, consult the following table before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/No sound | Blown fuse, loose power/ground/remote wire, amplifier in protect mode. | Check and replace fuses. Verify all power, ground, and remote connections are secure. Check for shorted speaker wires. |
| Distorted sound | Gain set too high, improper crossover settings, poor quality audio source. | Reduce gain. Adjust HPF/LPF settings. Ensure head unit output is clean. |
| Amplifier overheating | Insufficient ventilation, impedance too low, prolonged high volume use. | Ensure adequate airflow around the amplifier. Check speaker impedance. Reduce volume or allow amplifier to cool. |
| No sound from one channel | Faulty RCA cable, loose speaker wire, damaged speaker. | Check RCA connections. Verify speaker wire connections. Test speaker with another amplifier if possible. |
