Instalação passo a passo:
- Desconecte a bateria: Antes de começar, desconecte o terminal negativo da bateria do seu veículo para evitar curtos-circuitos.
- Escolha o local de montagem: Select a secure, dry location, typically under a seat or in the trunk. Ensure adequate ventilation around the unit. Use the included mounting brackets and screws for a firm installation.
- Fiação de energia:
- +12V (Alimentação): Connect a suitable gauge power wire (e.g., 8-gauge) directly from the vehicle's positive battery terminal to the +12V terminal on the subwoofer. Install an in-line fuse (not included, recommended 20A) within 18 inches of the battery.
- GND (Terra): Connect a short (less than 3 feet) and equally thick ground wire from the GND terminal on the subwoofer to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- REM (Ativação Remota): Connect a remote turn-on wire from your head unit's remote output (typically blue/white wire) to the REM terminal on the subwoofer. This wire signals the subwoofer to turn on/off with your head unit. If your head unit lacks a remote output, the RLS8 features an auto turn-on function via high-level inputs.
- Conexão de entrada de áudio:
- Entrada RCA: If your head unit has RCA pre-outs, connect RCA cables from the head unit to the RCA INPUTs (L and R) on the subwoofer.
- Entrada de alto nível: If your head unit does not have RCA pre-outs, use the included high-level input harness. Connect the speaker wires from your head unit (or factory speaker wires) to the corresponding wires on the high-level input harness. Plug the harness into the HIGH INPUT port on the subwoofer.
- Botão de graves remoto: Connect the wired remote bass knob to the 'REMOTE' port on the subwoofer. Route the cable to a convenient location for the driver.
- Reconecte a bateria: Once all connections are secure and verified, reconnect the negative battery terminal.

Instruções de operação
Adjust the subwoofer settings to achieve optimal bass response for your vehicle and listening preferences.
Control Panel Adjustments:
- Ganho de entrada: This control matches the output level of your head unit to the subwoofer. Start with the gain at minimum, then slowly increase it until you hear distortion, then back off slightly.
- Filtro passa-baixo (LPF): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust between 50Hz and 150Hz. A common starting point is 80-100Hz. Experiment to blend the subwoofer's output seamlessly with your main speakers.
- Reforço de graves: This control provides an increase in bass output at a specific frequency. Use sparingly to avoid distortion. The RLS8 offers up to +18dB of bass boost.
- Interruptor de fase (0°/180°): This switch helps to correct phase alignment issues between the subwoofer and your main speakers. Listen to music with strong bass and switch between 0° and 180° to determine which setting provides the most impactful and cohesive bass.
- Botão de graves remoto: This knob provides convenient control over the subwoofer's output level from the driver's seat. It adjusts the overall bass volume without affecting other settings.
