5.2. Wiring (Dual 4-Ohm Voice Coils)

The SW12A-D4 features dual 4-ohm voice coils, offering flexibility in wiring configurations to match your amprequisits d'impedància del lificador. Assegureu-vos sempre que ampEl lifter és estable a la impedància escollida.

• Cablejat en paral·lel (càrrega de 2 ohms): Connect the positive (+) terminals of both voice coils together, and the negative (-) terminals of both voice coils together. Then connect the combined positive to the ampla sortida positiva del lificador i la negativa combinada a la ampsortida negativa del transformador. Aquesta configuració resulta en una càrrega de 2 ohms.
• Cablejat en sèrie (càrrega de 8 ohms): Connect the positive (+) terminal of one voice coil to the negative (-) terminal of the other voice coil. Then connect the remaining positive (+) terminal to the amplifier's positive output and the remaining negative (-) terminal to the ampsortida negativa del transformador. Aquesta configuració resulta en una càrrega de 8 ohms.

Consulteu el vostre amplifier's manual for recommended impedance loads. Incorrect impedance can lead to amplifier damage or reduced performance.

5.3. Enclosure Recommendations

The type and size of the enclosure significantly impact subwoofer performance. The following are general recommendations:

• Sealed Enclosure Volume: 0.8 - 1.5 cubic feet (22.6 - 42.5 liters)
• Ported Enclosure Volume: 1.0 - 1.75 cubic feet (28.3 - 49.6 liters)

These are starting points; fine-tuning may be necessary based on your specific vehicle and listening preferences. Consult with a car audio specialist for custom enclosure designs.

6. Instruccions de funcionament

Once installed, follow these steps for initial operation and optimal performance:

1. Engegada inicial: After installation, turn on your head unit and amplifier at a low volume setting.
2. Ajust de guany: Carefully adjust the gain setting on your amplifier. Do not set the gain too high, as this can lead to distortion and damage to the subwoofer. Use a multimeter or oscilloscope for precise gain setting if possible.
3. Configuració de crossover: Configureu el filtre de pas baix (LPF) al vostre amplifier or head unit to filter out frequencies above the subwoofer's optimal range (typically 60-100 Hz). This ensures the subwoofer only reproduces bass frequencies.
4. Filtre subsònic: Si el teu amplifier has a subsonic filter, set it to protect the subwoofer from playing frequencies below its resonant frequency (Fs). For the SW12A-D4 (Fs: 33 Hz), a setting around 25-30 Hz is often appropriate.
5. Període d'entrada: Allow a break-in period of several hours of moderate listening before pushing the subwoofer to its limits. This allows the suspension components to loosen up and reach their optimal performance.
