Instruccions de funcionament
Once the subwoofer is installed and wired correctly, follow these steps for initial operation:
- Engegada inicial: Reconnect the vehicle's negative battery terminal. Turn on your head unit. The amplifier and subwoofer should power on.
- Configuració de guany: Comença amb el amplifier's gain control at its minimum setting. Play a familiar piece of music with strong bass. Slowly increase the gain until you hear distortion, then back off slightly. This ensures the amplifier is not overdriving the subwoofer.
- Configuració de crossover: Feu servir el filtre de pas baix (LPF) del vostre amplifier or head unit to send only low frequencies to the subwoofer. A common starting point is 80-100 Hz. Adjust this setting to blend seamlessly with your vehicle's main speakers.
- Control de fase: Alguns amplifiers have a phase switch (0° or 180°). Experiment with both settings to determine which provides the most impactful and coherent bass response in your listening position.
- Intensificació dels sons més greus: Use bass boost sparingly, if at all. Excessive bass boost can lead to distortion and potential damage to the subwoofer.
Allow the subwoofer to break in for several hours of normal use before playing at maximum volume. This allows the suspension components to loosen up and perform optimally.
