2. Sambungan Pendawaian
All wiring should be performed with the vehicle's battery disconnected to prevent electrical shorts and damage.
- Bekalan Kuasa: Connect the main power cable (BATTERY) to the positive terminal of the vehicle's battery. Use a fuse (not included) as close to the battery as possible.
- Tanah: Connect the ground cable (GROUND) to a clean, unpainted metal surface on the vehicle's chassis. A solid ground connection is critical to prevent noise and ensure stable operation.
- Hidupkan Jauh: Connect the remote turn-on cable (REMOTE) to the remote output of your head unit or a switched 12V source.
- Output pembesar suara: Utilize the quick-connect speaker connectors for channels 1-4 and the subwoofer output. Ensure correct polarity for all speakers.
- Input: Connect RCA cables from your head unit's pre-outs to the amplifier's CH-1/CH-2, CH-3/CH-4, and SUB W. (L/R) inputs.
- Kawalan Bes Jauh: Connect an optional remote bass control unit to the dedicated port for convenient subwoofer level adjustment.

3. Tetapan Awal
After wiring, adjust the amplifier's settings. These controls are located on the front panel, accessible by removing the trim ring.
- Kawalan Keuntungan: Adjust the GAIN for each channel pair (CH-1/2, CH-3/4, SUB W.) to match the output voltage of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
- Penapis Crossover:
- HP Filter (High-Pass Filter): For full-range speakers (CH-1/2, CH-3/4), set the HP filter to prevent low frequencies from reaching them, improving clarity.
- LP Filter (Low-Pass Filter): For the subwoofer channel (SUB W.), set the LP filter to allow only low frequencies to pass, ensuring proper bass reproduction.
- Penapis Subsonik: For the subwoofer channel, the SUBSONIC LP FILTER helps protect the subwoofer from extremely low, inaudible frequencies that can cause damage.
