4. Nastavitev in namestitev

Pravilna namestitev je ključnega pomena za optimalno delovanje in varnost. Pazljivo sledite tem korakom.

4.1 Mesto pritrditve

Choose a secure location in your vehicle, such as the trunk or under a seat, where the subwoofer will not shift during driving. Ensure adequate ventilation around the ampdvižna plošča.

The QB10SPA offers both low-level (RCA) and high-level (speaker wire) input options.

Napajalne povezave:

1. Moč (+12V): Connect a suitable gauge power wire (e.g., 8 AWG) directly from the vehicle's positive battery terminal to the +12V terminal on the subwoofer. Install an in-line fuse (not supplied, typically 30A) within 18 inches of the battery.
2. Ozemljitev (GND): Connect a short, heavy gauge ground wire (e.g., 8 AWG) from the GND terminal to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
3. Daljinski upravljalnik (REM): Connect a remote turn-on wire from your head unit's remote output to the REM terminal. If your head unit does not have a remote output, you can use the high-level input with DC offset sensing (see below).

Avdio vhodne povezave:

• Nizkonapetostni vhod (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer or full-range outputs to the L and R LOW INPUT jacks on the subwoofer.
• Visokonivojski vhod (nivo zvočnika): If your head unit does not have RCA outputs, use the supplied high-level input harness. Connect the speaker wires from your head unit's speaker outputs to the corresponding wires on the harness. The QB10SPA features DC offset sensing, which can automatically turn the subwoofer on when it detects an audio signal, eliminating the need for a separate remote wire.

5. Upravljanje in nastavitve

Once installed, you can fine-tune the subwoofer's performance using the controls on the amplifier panel and the remote bass knob.

5.1 AmpKontrole lifierja:

• GAIN (vhodna raven): This control matches the output of your head unit to the input of the subwoofer. Start with the gain at minimum. Play a familiar track and slowly increase the gain until you hear distortion, then back off slightly.
• LPF (nizkopasovni filter): This control sets the upper frequency limit for the subwoofer, allowing only frequencies below the set point to pass through. Adjust between 50 Hz and 250 Hz to blend the subwoofer's output seamlessly with your main speakers. A common starting point is 80-100 Hz.

5.2 Remote Bass Knob:

The included remote bass knob allows for convenient, on-the-fly adjustment of the subwoofer's output level from the driver's seat.

• Mount the knob in an easily accessible location.
• Use the dial to increase or decrease the bass level as desired.
