2.2 Sambungan Pendawaian

Proper wiring is crucial for optimal performance and safety. Refer to the subwoofer's rear panel for connection points.

• Kuasa (+12V): Connect to the positive terminal of your vehicle's battery. An in-line fuse (not included, but highly recommended within 12 inches of the battery) should be used for protection. The subwoofer has a built-in 15A fuse.
• Tanah (GND): Connect to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid connection for proper grounding.
• Penghidupan Jauh (REM): This terminal is optional. The QBUS10P features an automatic turn-on circuit that senses audio input (either high-level or low-level RCA) and powers on the subwoofer. If using this feature, the REM terminal does not need to be connected. If your head unit provides a dedicated remote turn-on output, you may connect it here and disable the auto-turn-on feature via the switch on the unit.
• Input (Low-Level RCA): For head units with RCA pre-outs, connect RCA cables from the head unit's subwoofer output to the QBUS10P's Low-Level inputs.
• Input (High-Level): For factory or aftermarket head units without RCA pre-outs, use the included high-level input harness. Connect the speaker wires from your head unit's speaker outputs to the corresponding wires on the harness, then plug the harness into the High-Level input port.

• Bass Boost (0dB-12dB): Increases the output at a specific low frequency. Use sparingly to avoid distortion.
• Input Volts (0.15V-6V): Padan dengan keluaran voltage of your head unit's RCA pre-outs or speaker-level outputs to the subwoofer's input sensitivity. Adjust this for optimal signal level without distortion.
