5. Installation
Choosing a Mounting Location:
- Select a secure, dry location away from direct sunlight and heat sources.

- Ensure adequate ventilation around the unit.
Wiring Connections:
- Power (BATT+): Connect the yellow wire directly to the vehicle's positive battery terminal using an appropriate fuse (not included, typically 15-20A).
- Ground (GND): Connect the black wire securely to a clean, unpainted metal surface of the vehicle chassis.
- Remote (REM): Connect the blue wire to the remote turn-on output of your head unit. If no remote output is available, connect to an accessory power source that turns on with the ignition.
- Audio Input:
- Low-Level Input (RCA): Connect RCA cables from your head unit's subwoofer output to the RCA inputs on the subwoofer.
- High-Level Input (Speaker): If your head unit does not have RCA outputs, use the provided speaker-level input harness. Connect the speaker wires from your head unit to the corresponding wires on the harness.
Remote Bass Level Control:
Connect the remote bass control module to the designated port on the subwoofer. Mount the control in an accessible location for easy adjustment.

6. Operation
Once installed, follow these steps to configure your subwoofer:
- Gain Control (GAIN): Start with the gain control set to minimum. Turn on your head unit and slowly increase the gain until the subwoofer output matches the rest of your audio system without distortion.
- Low Pass Filter (FREQ): Adjust the frequency knob (30Hz-100Hz) to blend the subwoofer's output seamlessly with your main speakers. A common starting point is around 80Hz.
- Phase Control (PHASE): Set the phase switch to 0° initially. If the bass sounds weak or out of sync, switch it to 180°. Choose the setting that provides the most impactful and coherent bass response.
- Remote Bass Control: Use the wired remote control to adjust the bass level conveniently from your driving position.

- Do not use harsh chemicals or solvents.
- Ensure proper ventilation and keep the grille free from obstructions.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power | Blown fuse; Loose power/ground wire; No remote turn-on signal. | Check and replace fuse; Secure all power and ground connections; Verify remote wire connection to head unit or accessory source. |
| No Sound | Incorrect input connection; Gain too low; Head unit settings. | Ensure RCA or speaker-level inputs are correctly connected; Increase gain control; Check head unit's subwoofer output settings. |
| Distorted Sound | Gain too high; Incorrect frequency setting; Poor ground connection. | Reduce gain; Adjust low pass filter (FREQ); Ensure ground wire is securely connected to a clean metal surface. |
| Weak Bass | Phase incorrect; Gain too low; Subwoofer placement. | Toggle phase switch (0°/180°); Increase gain; Experiment with subwoofer placement in the vehicle. |
