2.2 വയറിംഗ് കണക്ഷനുകൾ
Proper wiring is crucial for optimal performance and safety. Refer to the subwoofer's rear panel for connection points.
- പവർ (+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.
- ഗ്രൗണ്ട് (GND): Connect to a clean, unpainted metal surface on the vehicle's chassis. Ensure a solid connection for proper grounding.
- റിമോട്ട് ടേൺ-ഓൺ (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 മ ing ണ്ടിംഗ് സ്ഥാനം
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.
- സുരക്ഷിത മൗണ്ടിംഗ്: 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:
- ഫേസ് സ്വിച്ച് (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): ഔട്ട്പുട്ട് വോള്യവുമായി പൊരുത്തപ്പെടുന്നുtage 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 റിമോട്ട് ബാസ് നോബ്
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.

4. പരിപാലനം
To ensure the longevity and optimal performance of your NVX QBUS10P subwoofer, follow these general maintenance guidelines:
- വൃത്തിയാക്കൽ: Use a soft, dry cloth to wipe down the exterior of the subwoofer. Avoid using harsh chemicals or abrasive cleaners.
- വെൻ്റിലേഷൻ: Ensure the subwoofer's vents are not obstructed to allow for proper heat dissipation.
- കണക്ഷൻ പരിശോധനകൾ: Periodically inspect all wiring connections (power, ground, inputs) to ensure they are secure and free from corrosion.
5. പ്രശ്നപരിഹാരം
If you experience issues with your QBUS10P subwoofer, consult the following table:
| പ്രശ്നം | സാധ്യമായ കാരണം | പരിഹാരം |
|---|---|---|
| വൈദ്യുതിയില്ല (പവർ LED ഓഫ്) | Blown fuse; Loose power/ground connection; No remote turn-on signal (if auto-on is off) | Check and replace 15A fuse; Verify all power and ground connections; Ensure auto-on is enabled or remote wire is connected and receiving signal. |
| No Sound (Power LED On) | Input signal issue; Gain/Input Volts set too low; Low-Pass Filter set too low; Phase incorrect | Check RCA/High-Level input connections; Adjust Gain/Input Volts; Adjust LPF; Experiment with Phase switch. |
| വികലമായ ശബ്ദം | Gain/Input Volts set too high; Bass Boost too high; Poor input signal quality | Reduce Gain/Input Volts; Lower Bass Boost; Check head unit settings and input signal quality. |
| Subwoofer Overheating (Protect LED On) | Insufficient ventilation; Impedance mismatch; Prolonged high-volume use | Ensure proper airflow around the unit; Verify speaker impedance (4 Ohm); Reduce volume or allow unit to cool down. |
