Power Connections:
- +12V (Power): Connect directly to the positive terminal of the vehicle's battery using a suitable gauge power cable with an inline fuse (25A recommended, typically included).
- GND (Ground): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid connection for optimal performance and safety.
- REM (Remote Turn-On): Connect to the remote turn-on output of your head unit. This signal turns the subwoofer on and off with your car stereo.
Audio Input Connections:
- Low Level Input (RCA): Use RCA cables to connect to the subwoofer pre-out of your head unit. This is the preferred method for best audio quality.
- High Level Input: If your head unit does not have RCA outputs, use the included high-level input harness to connect to your vehicle's speaker wires. The unit features an "Auto Power On" function that can detect an audio signal from high-level inputs to turn on the subwoofer.
Remote Level Control:
- Connect the remote level control knob to the "REMOTE" port on the subwoofer. Mount the knob in an accessible location for easy adjustment of the subwoofer's output level.
6. Operating Instructions
Once installed and wired, you can adjust the subwoofer's settings using the controls on the unit and the remote level knob.
6.1 Control Panel Adjustments
- GAIN (Input Level): Adjust this control to match the output level of your head unit. Start at minimum and slowly increase until you hear distortion, then back off slightly.
- LPF (Low Pass Filter): This control sets the upper frequency limit for the subwoofer, ranging from 85Hz to 150Hz. Adjust it to blend the subwoofer's output smoothly with your main speakers.
- VEGA BASS (Bass Boost): Provides an adjustable bass boost from 0 to +12dB at 45Hz. Use sparingly to avoid distortion.
- PHASE: Select 0° or 180°. This adjusts the phase of the subwoofer's output relative to your main speakers. Choose the setting that provides the most impactful and cohesive bass response from your listening position.
- AUTO POWER ON: If using high-level inputs, set this switch to ON. The subwoofer will automatically turn on when it detects an audio signal. If using the remote turn-on wire, set this to OFF.
6.2 Remote Level Control
The included remote knob allows for convenient adjustment of the subwoofer's output level from the driver's seat without needing to access the unit directly.
7. Maintenance
- Keep the subwoofer clean by wiping it with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Ensure that the area around the subwoofer remains clear of obstructions to allow for proper heat dissipation.
- Periodically check all wiring connections for tightness and corrosion.
- If the fuse blows, replace it only with a fuse of the same type and rating (25A).
