4.2 Wiring the Subwoofer

The RW8D4 features dual 4-ohm voice coils, offering flexibility in wiring configurations (series or parallel) to achieve the desired impedance for your amplifier. Consult your ampmanual del lificador per a càrregues d'impedància compatibles.

• Cablejat en paral·lel (2 ohms): Connecteu els terminals positius de les dues bobines de veu i els terminals negatius de les dues bobines de veu. A continuació, connecteu el positiu combinat al ampla sortida positiva del lificador i la negativa combinada a la ampsortida negativa del lificador.
• Cablejat en sèrie (8 ohms): Connecteu el terminal positiu d'una bobina mòbil al terminal negatiu de l'altra bobina mòbil. A continuació, connecteu el terminal positiu restant al ampla sortida positiva del lificador i el terminal negatiu restant al ampsortida negativa del lificador.

Ensure all connections are secure and properly insulated. The voice coils are coated with black glue designed to handle extremely high temperatures, contributing to the subwoofer's power handling capabilities.

5. Instruccions de funcionament

Once installed, connect the subwoofer to a suitable amplifier. The RW8D4 is designed to be controlled by the amplifier's output, which in turn is controlled by the vehicle's head unit or audio source.

• Engegada inicial: Comença amb el amplifier's gain control at its lowest setting. Gradually increase the volume from your head unit.
• Ajust de guany: Carefully adjust the ampguany del lificador per coincidir amb el volum de sortidatagde la unitat principal. Eviteu configurar el guany massa alt, ja que això pot provocar distorsió i possibles danys al subwoofer.
• Configuració de crossover: Utilize the low-pass filter (LPF) on your amplifier or head unit to send only low-frequency signals to the subwoofer. A typical crossover point for an 8-inch subwoofer might be between 80Hz and 120Hz, but this can vary based on your vehicle and personal preference.
• Control de fase: Experimenta amb el commutador de fase (0° o 180°) del teu amplifier to achieve the best blend with your front speakers.

The subwoofer's high-strength pressed paper cone and NBR surround are engineered for sound quality with minimal distortion.

6. Manteniment

Un manteniment regular ajuda a garantir la longevitat i el rendiment del subwoofer.

• Neteja: Use a soft, dry cloth to wipe down the cone and surround. Avoid using harsh chemicals or excessive moisture.
• Inspecció: Periodically check all wiring connections for tightness and corrosion. Inspect the subwoofer cone and surround for any signs of damage or wear.
