Wiring Connections

The PLMRBS8 supports both low-level (RCA) and high-level (speaker wire) inputs, offering versatility for connection to various head units or audio sources.

• Power Connection: Connect the main power wire to the positive terminal of your vehicle's battery. Ensure an inline fuse (2x15A recommended) is installed close to the battery. Connect the ground wire to a clean, unpainted metal surface on the vehicle's chassis.
• Remote Turn-On: Connect the remote turn-on wire to the remote output of your head unit. This allows the subwoofer to turn on and off with your audio system.
• Audio Input:
  • RCA Input: For head units with RCA pre-outs, connect RCA cables from the head unit's subwoofer or full-range outputs to the RCA inputs on the PLMRBS8.
  • High-Level Input: If your head unit does not have RCA outputs, use the high-level inputs. Connect the speaker wires from your head unit's speaker outputs directly to the high-level input terminals on the subwoofer.

Operating Instructions

Once installed, adjust the settings on your PLMRBS8 for optimal audio performance.

Controls and Adjustments

• Input Gain (Level Control): This knob adjusts the input sensitivity of the subwoofer (0.2V-3V). Start with the gain set to minimum and slowly increase it until the desired volume is achieved without distortion.
• Low Pass Filter (LPF): The LPF control (50-150 Hz) allows you to set the upper frequency limit for the subwoofer. Frequencies above this setting will be filtered out, ensuring the subwoofer only reproduces bass notes.
• Bass Boost: This control (0 to +12dB @45Hz) allows you to enhance the bass output at 45Hz. Use sparingly to avoid distortion.
• Phase Shift: The phase switch (0° or 180°) helps to align the subwoofer's output with the main speakers. Experiment with both settings to find the one that provides the most cohesive bass response.
• Remote Level Control: Connect the included remote control module to the "REMOTE CONTROL" port. This allows for convenient adjustment of the subwoofer's output level from your listening position.

Maintenance

The Pyle PLMRBS8 is designed for durability in marine environments. Regular maintenance is minimal but important for longevity:

• Cleaning: Wipe the unit with a soft, damp cloth to remove dust and grime. Avoid harsh chemicals or abrasive cleaners.
• Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion, especially in marine applications.
• Ventilation: Ensure the area around the subwoofer remains clear to allow for proper heat dissipation.
