5. Installation
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 Monteringssted
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 Ledningsforbindelser
- Strøm (BATTERI +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.
- Jord (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.
- Fjerntænding (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.
- Lydindgang:
- Lavniveauindgang (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.
- Secure all connections: Double-check all wiring for proper polarity and secure connections.
6. Betjening og justeringer
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.
- Lavpasfilter (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.
- Faseskift (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.
- Bass Boost: Use the bass boost control sparingly to add emphasis to low frequencies. Excessive bass boost can lead to distortion and potential damage.
- Tænd kontakt: 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. Vedligeholdelse
- Rensning: Brug en blød, tør klud til at rengøre subwooferens yderside. Brug ikke skrappe kemikalier eller slibende rengøringsmidler.
- Forbindelser: Kontrollér regelmæssigt alle ledningsforbindelser for at sikre, at de er fastgjorte og fri for korrosion.
- Ventilation: Ensure the subwoofer's ventilation openings are not blocked to prevent overheating.
8. Fejlfinding
If you experience problems with your subwoofer, refer to the following table for common issues and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Sprunget sikring, løs strøm-/jordforbindelse, intet fjernsignal. | Check/replace fuse, verify all power/ground/remote connections, ensure 'Turn On' switch is correctly set. |
| Ingen lyd | 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. |
| Forvrænget lyd | 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. |
| Svag 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. Brugertips
- Indledende opsætning: 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.
- Fasejustering: Don't skip adjusting the phase. It can significantly improve bass impact and clarity, making the subwoofer sound more integrated with your main speakers.
- Lavpasfilter: 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.
- Sikker montering: Ensure the subwoofer is very securely mounted. A loose subwoofer can rattle, produce poor bass, and become a safety hazard in a collision.
- Strømledninger: 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.
