5. Instalacja
Proper installation is crucial for performance and safety. If you are not confident in your ability to perform the installation, please consult a qualified car audio professional.
5.1 Miejsce montażu
Choose a secure, dry location, typically under a seat, that allows for adequate ventilation and does not interfere with vehicle controls or passenger safety. Ensure the mounting surface is strong enough to support the subwoofer's weight.
5.2 połączeń przewodów
- Moc (BATT +12V): Connect a suitable gauge power wire directly from the vehicle's positive battery terminal to the +12V input on the subwoofer's wiring harness. Install the provided 20A fuse within 18 inches (45 cm) of the battery.
- Masa (GND): Connect a suitable gauge ground wire from the subwoofer's wiring harness to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Zdalne włączanie (REM): Connect a wire from your head unit's remote output (usually blue/white) to the REM input on the subwoofer's wiring harness. If your head unit does not have a remote output, use the 'DC Offset' or 'Audio Sense' options on the 'Turn On' switch.
- Wejście audio:
- Wejście niskopoziomowe (RCA): Connect RCA cables from your head unit's subwoofer or full-range RCA outputs to the 'Line In' RCA inputs on the subwoofer.
- High-Level Input (Speaker In): If your head unit does not have RCA outputs, connect your vehicle's speaker wires directly to the 'Speaker In' terminals on the subwoofer's wiring harness. Observe correct polarity.
- Zabezpiecz wszystkie połączenia: Double-check all wiring for proper polarity and secure connections.
6. Obsługa i regulacje
Once installed, you can fine-tune the subwoofer's performance using the control panel.
- Gain Control: Start with the gain control at its minimum setting. Play a familiar piece of music with strong bass. Slowly increase the gain until the bass output blends well with the rest of your audio system without distortion.
- Filtr dolnoprzepustowy (LPF): Adjust the LPF to cut off frequencies above the desired range for the subwoofer. A common starting point is 80-100Hz. Experiment to find the best blend with your main speakers.
- Zmiana fazy (0°/180°): Listen to the bass from the driver's seat. Flip the phase switch between 0° and 180°. Choose the setting that provides the most impactful and coherent bass response.
- Wzmocnienie basów: Use the bass boost control sparingly to add emphasis to low frequencies. Excessive bass boost can lead to distortion and potential damage.
- Włącz przełącznik: Set this switch based on your wiring. 'Remote' for a dedicated remote wire, 'DC Offset' if your head unit provides a DC offset on the speaker outputs, or 'Audio Sense' if the subwoofer should turn on when it detects an audio signal.
7. Konserwacja
- Czyszczenie: Do czyszczenia obudowy subwoofera używaj miękkiej, suchej ściereczki. Nie używaj silnych środków chemicznych ani ściernych środków czyszczących.
- Znajomości: Okresowo sprawdzaj wszystkie połączenia przewodów, aby mieć pewność, że są solidne i nie są skorodowane.
- Wentylacja: Ensure the subwoofer's ventilation openings are not blocked to prevent overheating.
8. Rozwiązywanie Problemów
If you experience problems with your subwoofer, refer to the following table for common issues and solutions:
| Problem | Możliwa przyczyna | Rozwiązanie |
|---|---|---|
| Brak zasilania | Przepalony bezpiecznik, luźne połączenie zasilania/uziemienia, brak sygnału zdalnego. | Check/replace fuse, verify all power/ground/remote connections, ensure 'Turn On' switch is correctly set. |
| Brak dźwięku | Incorrect input connection, gain too low, LPF set too low, head unit settings. | Verify audio input connections (RCA or speaker level), increase gain, adjust LPF, check head unit's subwoofer output settings. |
| Zniekształcony dźwięk | Gain too high, bass boost too high, LPF set too high, poor input signal. | Reduce gain, reduce bass boost, adjust LPF, check input signal quality. |
| Słaby bas | Phase mismatch, gain too low, LPF set too low, subwoofer not properly mounted. | Toggle phase switch, increase gain, adjust LPF, ensure secure mounting. |

10. Wskazówki użytkownika
- Początkowe ustawienia: When first setting up, start with the gain at minimum and gradually increase it. This prevents accidental overdriving and potential damage to the subwoofer or your ears.
- Regulacja fazy: Don't skip adjusting the phase. It can significantly improve bass impact and clarity, making the subwoofer sound more integrated with your main speakers.
- Filtr dolnoprzepustowy: Experiment with the LPF setting. A good starting point is often around 80Hz, but it depends on your main speakers' low-frequency capabilities. The goal is a seamless transition between the subwoofer and your other speakers.
- Bezpieczne mocowanie: Ensure the subwoofer is very securely mounted. A loose subwoofer can rattle, produce poor bass, and become a safety hazard in a collision.
- Okablowanie zasilania: Always use a dedicated power wire directly from the battery with an inline fuse. Do not tap into existing power wires that may not be rated for the subwoofer's current draw.
