5. Setup and Installation
5.1 Mounting Location
Choose a mounting location that is dry, well-ventilated, and provides sufficient space for wiring and air circulation. Avoid mounting the amplifier directly on carpet or in enclosed spaces that can restrict airflow. Secure the amplifier firmly using the provided mounting hardware.
5.2 Wiring Connections
Ensure all connections are secure and properly insulated to prevent short circuits. Refer to Figure 4.2 for terminal locations.
- Power (+12V): Connect a direct wire from the positive terminal of your vehicle's battery to the +12V terminal on the amplifier. Use an appropriate gauge wire (e.g., 8-gauge or thicker for runs up to 17 feet) and install an in-line fuse holder within 18 inches of the battery.
- Ground (GND): Connect a wire of the same gauge as the power wire from the GND terminal to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Remote (REM): Connect this terminal to the remote turn-on output of your head unit. This wire signals the amplifier to turn on and off with your car's audio system. If using high-level inputs, the amplifier features an auto-turn on function.
- Speaker Output: Connect your subwoofer(s) to the SPEAKER terminals. This amplifier is 2 Ohm stable. Ensure your subwoofer's impedance (or combined impedance for multiple subwoofers) is within the amplifier's stable operating range (2 or 4 Ohms).
- Audio Input (RCA or High-Level):
- RCA Input: Connect RCA cables from your head unit's subwoofer pre-out to the LINE-INPUT (RCA) terminals on the amplifier.
- High-Level Input: If your head unit does not have RCA outputs, use the HI-INPUT (AUTO-ON) terminal. Connect the speaker wires from your head unit directly to this input. The amplifier will automatically turn on when it detects an audio signal.
- Remote Subwoofer Controller: Connect the remote level controller to the REMOTE port on the amplifier. This allows for convenient bass level adjustment from the driver's seat.
6. Operating Instructions and Adjustments
After installation, carefully adjust the amplifier settings for optimal sound performance.
- LEVEL (Input Gain Control): This control matches the amplifier's input sensitivity to the output of your head unit. Start with the LEVEL control at minimum (MIN). Play a familiar track at about 75% of your head unit's maximum volume. Slowly increase the LEVEL control on the amplifier until you hear slight distortion, then back it off slightly. The range is 0.2V to 8V.
- LPF (Low-Pass Filter): This filter allows only frequencies below the set point to pass through to the subwoofer. The variable range is 50Hz to 250Hz. Adjust this to blend your subwoofer with your main speakers. A common starting point is 80Hz.
- BASS (Bass Boost): This control provides a variable bass boost from 0dB to 12dB at 50Hz. Use sparingly to enhance bass response. Excessive boost can lead to distortion and potential speaker damage.
- X-OVER (Mode Switch): This switch selects between Full Range and LPF (Low-Pass Filter) modes. For subwoofer applications, set this to LPF.
- Remote Subwoofer Controller: Use the wired remote to conveniently adjust the subwoofer output level from your listening position.
7. Troubleshooting
If you experience issues with your amplifier, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power (Power LED Off) | Blown fuse, poor power/ground connection, no remote turn-on signal. | Check amplifier fuse, vehicle's main fuse. Verify +12V, GND, and REM connections. Ensure head unit is on and sending a remote signal. |
| Protection LED On | Speaker short circuit, impedance too low, overheating, DC offset. | Check speaker wiring for shorts. Verify subwoofer impedance is 2 Ohm or higher. Ensure adequate ventilation. Disconnect speakers and test. |
| No Sound (Power LED On) | No audio input signal, incorrect gain setting, speaker wires disconnected. | Check RCA or high-level input connections. Adjust LEVEL control. Verify speaker connections. Test with a known working audio source. |
| Distorted Sound | Gain set too high, LPF set incorrectly, poor ground connection, damaged speaker. | Reduce LEVEL control. Adjust LPF. Check ground connection. Inspect subwoofer for damage. |
If problems persist after following these steps, contact OceanAudio customer support.
