Cableado en paralelo (2 ohmios): 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.
Cableado en serie (8 ohmios): 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.

Asegúrate sempre do teu 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. Instrucións de funcionamento

Once installed, proper operation of your subwoofer involves careful adjustment of your amplifier and head unit settings.

Configuración de ganancia: Establece o ampganancia do lificador correctamente para coincidir co volume de saídatage 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.
Filtro paso baixo (LPF): Usa o filtro de paso baixo no teu 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.
Filtro subsónico: Se o 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.
Boost de baixo: Use bass boost sparingly, if at all. Excessive bass boost can lead to distortion and potential damage to the subwoofer.
Período de rodaxe: Deixa un período de axuste de aproximadamente 20-30 horas de escoita moderada antes de levar o subwoofer ao límite. Isto permite que os compoñentes da suspensión se afrouxen e funcionen de forma óptima.
