Ensure the mounting surface is rigid and free from obstructions. Use appropriate tools for cutting the mounting hole to the specified diameter.
3.3 Wiring the Dual 4-Ohm Voice Coils
The WDX8G2.4 features dual 4-ohm voice coils, offering flexibility in wiring configurations to match your amprequisits d'impedància del transformador.
- Cablejat en paral·lel (2 ohms): Connect the positive terminals of both voice coils together, and the negative terminals of both voice coils together. Then connect these combined positive and negative terminals to the amplifier. This configuration results in a 2-ohm load.
- Cablejat en sèrie (8 ohms): Connect the positive terminal of one voice coil to the negative terminal of the other voice coil. Then connect the remaining free positive and negative terminals to the amplifier. This configuration results in an 8-ohm load.
Assegureu-vos sempre el vostre amplifier is stable at the chosen impedance. Use high-quality, large-gauge speaker wire for all connections to minimize power loss and ensure optimal performance. Secure all connections firmly using the compression speaker terminals.

4. Instruccions de funcionament
Once installed, proper operation of your subwoofer involves careful adjustment of your amplifier and head unit settings.
- Configuració de guany: Estableix el ampguany del lificador correctament per coincidir amb el volum de sortidatage of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly. Never use the gain control as a volume knob.
- Filtre de pas baix (LPF): Feu servir el filtre de pas baix del vostre amplifier or head unit to ensure the subwoofer only reproduces low frequencies. A typical setting for an 8-inch subwoofer might be between 80 Hz and 120 Hz, but this can vary based on your full-range speakers and personal preference.
- Filtre subsònic: Si el teu amplifier has a subsonic filter, enable it and set it just below the tuning frequency of your ported enclosure (if applicable) to protect the subwoofer from over-excursion at very low frequencies.
- 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.
- Període d'entrada: Allow a break-in period of approximately 20-30 hours of moderate listening before pushing the subwoofer to its limits. This allows the suspension components to loosen up and perform optimally.
5. Manteniment
