Mount the amplifier securely to a solid surface using appropriate hardware. Ensure no wires are pinched or damaged during mounting.
2. Wiring Connections
Refer to the diagram below for typical wiring connections. Always use high-quality, appropriately gauged wiring.
- Power (B+): Connect directly to the positive terminal of the vehicle's battery via a fuse holder (fuse not included, ensure proper rating).
- Ground (GND): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid connection.
- Remote (REM): Connect to the remote turn-on output of your head unit.
- RCA Input: Connect RCA cables from your head unit's pre-out to the amplifier's RCA input jacks.
- Speaker Output: Connect your subwoofer(s) to the amplifier's speaker terminals. Ensure correct polarity and impedance matching (1 Ohm stable).

Operating Instructions
Once installed, the amplifier will power on automatically when your head unit is turned on (via the remote wire). Adjust gain and filter settings carefully to match your system components and preferences.
Amplifier Indicators
The amplifier features indicator lights to provide status information:

- Blue Indicator: Illuminates when the amplifier is powered on and receiving a source signal.
- Red Indicator: Illuminates to indicate output distortion. Reduce the gain or input level to prevent damage.
- Yellow Indicator (Flashing): Flashes when the input voltage is below the specified operating range. Check your vehicle's electrical system.
Maintenance
- Keep the amplifier clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure adequate airflow around the amplifier to prevent overheating.
- Periodically check all wiring connections for tightness and corrosion.
- Do not spray cleaning liquids directly onto the amplifier.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power / Amplifier does not turn on | Blown fuse; Loose power/ground/remote wire; Low battery voltage | Check and replace fuse; Verify all connections are secure; Check vehicle battery and charging system. |
| No Sound Output | Loose RCA cables; Incorrect gain settings; Speaker wires disconnected or shorted; Head unit not sending signal | Check RCA connections; Adjust gain; Inspect speaker wiring; Verify head unit operation. |
| Distorted Sound | Gain set too high; Speaker impedance mismatch; Damaged speaker; Poor ground connection | Reduce gain; Verify speaker impedance (1 Ohm minimum); Check speaker condition; Ensure solid ground connection. |
| Amplifier Overheats | Insufficient ventilation; Impedance too low; Prolonged high volume use | Ensure proper airflow; Verify speaker impedance; Reduce volume or allow cooling time. |
