Sambungan Kuasa:

1. Kuasa (+12V): Connect a suitable gauge power wire (e.g., 8 AWG) directly from the vehicle's positive battery terminal to the +12V terminal on the subwoofer. Install an in-line fuse (not supplied, typically 30A) within 18 inches of the battery.
2. Tanah (GND): Connect a short, heavy gauge ground wire (e.g., 8 AWG) from the GND terminal to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
3. Alat Kawalan Jauh (REM): Connect a remote turn-on wire from your head unit's remote output to the REM terminal. If your head unit does not have a remote output, you can use the high-level input with DC offset sensing (see below).

Sambungan Input Audio:

• Input Aras Rendah (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer or full-range outputs to the L and R LOW INPUT jacks on the subwoofer.
• Input Aras Tinggi (Aras Pembesar Suara): If your head unit does not have RCA outputs, use the supplied high-level input harness. Connect the speaker wires from your head unit's speaker outputs to the corresponding wires on the harness. The QB10SPA features DC offset sensing, which can automatically turn the subwoofer on when it detects an audio signal, eliminating the need for a separate remote wire.
