2. Sikkerhedsoplysninger
WARNING: Improper installation or use can result in serious injury or damage to your equipment. Always consult a professional if you are unsure about any installation steps.
- Elektriske farer: Disconnect the vehicle's battery before performing any electrical work. Ensure all wiring is properly insulated and secured to prevent short circuits.
- Høreværn: Prolonged exposure to high sound pressure levels can cause permanent hearing damage. Use appropriate hearing protection when operating the subwoofer at high volumes.
- Sikker montering: Ensure the subwoofer and its enclosure are securely mounted within the vehicle to prevent movement during sudden stops or collisions.
- Ventilation: Sørg for tilstrækkelig ventilation omkring subwooferen og ampfor at forhindre overophedning.
- Impedanstilpasning: Always match the subwoofer's impedance (Dual 2 Ohm) to your amplifier's output capabilities. Incorrect impedance can damage the amplifier eller subwoofer.

Note: Additional components such as an enclosure, amplifier, wiring kit, and installation hardware are sold separately and are required for a complete system.
4. Opsætning og installation
Proper installation is crucial for the performance and longevity of your subwoofer. It is highly recommended that installation be performed by a qualified car audio professional.
4.1. Valg af kabinet
The SDR-12 D2 subwoofer requires a suitable enclosure for optimal performance. Consult Skar Audio's recommended enclosure specifications for sealed or ported designs. The enclosure should be robust and free from air leaks.
4.2. Wiring and Impedance
The SDR-12 D2 features dual 2-ohm voice coils. This allows for various wiring configurations to achieve different final impedances, such as 1 ohm or 4 ohms, depending on your amplifier's capabilities. Refer to your amplifier's manual for compatible impedance loads.

4.3. Amplivligere forbindelse
- Connect the subwoofer's voice coils to your amplifier according to the desired impedance and the amplifiers specifikationer.
- Sørg for, at alle forbindelser er tætte og fri for korrosion.
- Route power and signal cables away from each other to minimize noise interference.
4.4. Indledende indstillinger
Before powering on, set your amplifier's gain to its minimum setting. Set the low-pass filter (LPF) to a suitable frequency (e.g., 80-100 Hz) and disable any bass boost or equalization for initial testing.
5. Betjeningsvejledning
5.1. Indkøringsperiode
Allow a break-in period of approximately 20-30 hours of normal listening before operating the subwoofer at maximum output. This allows the suspension components to loosen and perform optimally.
5.2. Justering af indstillinger
- Øg gradvist amplifier's gain until the desired volume is achieved without distortion.
- Adjust the LPF to blend the subwoofer's output seamlessly with your main speakers.
- Use caution with bass boost features, as excessive boost can lead to distortion and damage.

6. Vedligeholdelse
- Regelmæssig inspektion: Kontrollér regelmæssigt alle ledningsforbindelser for tæthed og tegn på slid eller korrosion.
- Rensning: Keep the subwoofer cone and surround free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or excessive moisture.
- Miljøfaktorer: Beskyt subwooferen mod ekstreme temperaturer, direkte sollys og fugt.
7. Fejlfinding
Hvis du oplever problemer med din subwoofer, kan du se følgende almindelige problemer og løsninger:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen lyd | Løse ledninger, amplifier off, incorrect settings, blown fuse. | Kontroller alle forbindelser, sørg for amplifier is powered on, verify settings, inspect fuses. |
| Forvrænget lyd | Gain too high, incorrect LPF setting, damaged voice coil, poor power supply. | Reducere amplifier gain, adjust LPF, check power and ground connections, inspect subwoofer for damage. |
| Overophedning af subwoofer | Insufficient ventilation, improper impedance, excessive power. | Ensure adequate airflow, verify impedance match, reduce power input. |
| Svag bas | Incorrect enclosure volume, phase issues, low gain setting. | Verify enclosure volume, check phase setting on amplifier, increase gain gradually. |
