2.2 ການເຊື່ອມຕໍ່ສາຍໄຟ

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

• ພະລັງງານ (+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.
• ດິນ (GND): Connect to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid connection for proper grounding.
• ການເປີດທາງໄກ (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.

2.3 ສະຖານທີ່ຕັ້ງ

The compact design of the QBUS10P allows for versatile mounting options, typically under a seat or in other confined spaces.

• Under Seat Mount: This is the primary intended mounting type, utilizing the available space beneath car seats. Ensure adequate clearance for air circulation and cable routing.
• ການຕິດຕັ້ງທີ່ປອດໄພ: Use the provided mounting brackets and screws to firmly secure the subwoofer to the vehicle's floor or a stable surface. This prevents movement and enhances bass performance.

3. Operating Controls and Adjustments

The QBUS10P offers several controls on its rear panel to fine-tune audio output:

• ສະຫຼັບໄລຍະ (0°/180°): Adjusts the phase of the subwoofer's output relative to the main speakers. Experiment with both settings to find the one that provides the most cohesive and impactful bass.
• Low-Pass Filter (LPF) (50Hz-150Hz): Controls the upper frequency limit of the subwoofer. Set this to blend smoothly with your main speakers, typically between 80Hz and 120Hz.
• Bass Boost (0dB-12dB): Increases the output at a specific low frequency. Use sparingly to avoid distortion.
• Input Volts (0.15V-6V): ກົງກັບຜົນຜະລິດ 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.
• Auto Power On Switch: Toggles the automatic turn-on feature. Set to 'ON' if using high-level or low-level inputs without a remote turn-on wire. Set to 'OFF' if using a dedicated remote turn-on wire.

3.1 Remote Bass Knob

The included remote bass knob provides convenient control over the subwoofer's output level from the driver's seat. Connect it to the 'REMOTE CONTROL' port on the subwoofer's rear panel.
