3. Setup
Proper installation is crucial for optimal performance and safety. Follow these steps for setting up your amplifier.
Mounting the Amplifier:
Choose a secure, dry location with sufficient airflow to prevent overheating. The amplifier can be surface mounted. Ensure it is not exposed to direct sunlight or excessive vibration.
Wiring Connections:
- Power (B+): Connect a heavy-gauge power cable (e.g., 4-gauge) directly from the positive terminal of the vehicle's battery to the amplifier's B+ terminal. Install an appropriate fuse holder within 18 inches of the battery.
- Ground (GND): Connect a heavy-gauge ground cable (e.g., 4-gauge) from the amplifier's GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid, low-resistance connection.
- Remote (REM): Connect a remote turn-on wire from your head unit's remote output to the amplifier's REM terminal. This wire turns the amplifier on and off with your head unit.
- RCA Inputs: Connect RCA cables from your head unit's subwoofer output to the amplifier's RCA input jacks.
- Speaker Output: Connect your subwoofer(s) to the amplifier's speaker output terminals using appropriate gauge speaker wire. Ensure correct polarity (+ to + and - to -).

4. Operating Instructions
Once installed, adjust the amplifier settings to optimize sound performance for your system.
Control Panel Adjustments:
- Level (Gain): Adjust this control to match the output voltage of your head unit. Start with the gain at minimum and slowly increase until you hear distortion, then back off slightly.
- Low-Pass Filter (LPF): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust between 40Hz and 300Hz to blend with your main speakers.
- Subsonic Filter: This filter removes extremely low frequencies that your subwoofer cannot reproduce efficiently, preventing damage and improving sound quality. Adjust between 10Hz and 40Hz.
- Bass EQ (Boost): Provides a boost to bass frequencies. Use sparingly to avoid distortion. Adjustable from 0dB to 12dB.
- Phase: Adjust the phase (0° or 180°) to ensure the subwoofer's output is in phase with the rest of your audio system, maximizing bass impact.
- Remote Bass Knob: Use the included remote bass knob for convenient real-time adjustment of the subwoofer level from the driver's seat.
LED Indicators:
- PWR (Green): Indicates the amplifier is powered on and operating normally.
- PRT (Red): Indicates the amplifier is in protection mode due to overheating, short circuit, or low voltage. Turn off the system and troubleshoot the issue.

5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your amplifier.
- Cleaning: Periodically clean the amplifier's exterior with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Ensure ventilation fins are free from dust and debris.
- Connection Check: Annually inspect all power, ground, remote, and speaker connections for tightness and corrosion. Loose connections can cause poor performance or damage.
- Ventilation: Ensure the amplifier's mounting location maintains good airflow. Clear any obstructions that might block the heat sink.
6. Troubleshooting
If you encounter issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (PWR LED Off) | Blown fuse, loose power/ground/remote wire, faulty wiring. | Check inline fuse, verify all connections are secure, test power/ground/remote wires for continuity. |
| Protection Mode (PRT LED On) | Overheating, short circuit in speaker wiring, low impedance load, low voltage. | Allow amplifier to cool, check speaker wiring for shorts, ensure correct impedance, verify vehicle's battery voltage. |
| No Sound Output | No signal from head unit, incorrect gain setting, faulty RCA cables, speaker issues. | Check head unit output, adjust gain, test RCA cables, verify speaker connections and functionality. |
| Distorted Sound | Gain set too high, incorrect LPF/Subsonic settings, poor quality audio source. | Reduce gain, adjust LPF/Subsonic filters, ensure high-quality audio input. |
