5.2 Koneksi Kabel
Mengacu kepada amplifier control panel diagram for correct wiring. Ensure all connections are tight and secure.
Gambar: Detail view dari amplifier control panel. This panel includes connections for power (GND, REM, +12V), fuse, high-level speaker inputs, RCA inputs, and RCA outputs, along with adjustment controls.
- Sambungan Daya (+12V): Connect an 8-gauge power cable directly from the vehicle's positive battery terminal to the "+12V" terminal on the amplifier. Install an appropriate fuse (30A) within 18 inches (45 cm) of the battery.
- Koneksi Tanah (GND): Connect an 8-gauge ground cable from the "GND" terminal on the amplifier to a clean, unpainted metal surface on the vehicle chassis. Ensure a good electrical connection.
- Pengaktifan Jarak Jauh (REM): Connect a remote turn-on wire from your head unit's remote output to the "REM" terminal on the amppenguat. Kabel ini mengubah ampMenghidupkan dan mematikan amplifier melalui head unit Anda.
- Masukan Audio:
- Input Level Rendah (RCA): If your head unit has RCA pre-outs, connect RCA cables from the head unit's subwoofer or rear pre-out to the "INPUT" RCA jacks on the amppengangkat.
- Input Tingkat Tinggi (Tingkat Speaker): If your head unit does not have RCA pre-outs, use the supplied high-level input harness. Connect the speaker wires from your head unit's rear speakers to the corresponding inputs on the harness, then plug the harness into the "SPK IN" connector on the amppengangkat.
- Kontrol Bass Jarak Jauh: Plug the remote bass control knob into the designated port on the amplifier. Mount the knob in a convenient location for easy access.

6.1 AmpKontrol pengangkat
- MENDAPATKAN: This control matches the input sensitivity of the amplifier to the output of your head unit. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly.
- LPF (Filter Lolos Rendah): Adjusts the upper frequency limit of the subwoofer. Typically set between 50Hz and 120Hz. Frequencies above this setting will be filtered out.
- PENINGKATAN BASS: Increases the bass output at 50Hz. Use sparingly to avoid distortion and potential damage. Adjustable from 0-6 dB.
- FASE: Allows you to adjust the phase of the subwoofer output (0° or 180°) to match the phase of your other speakers. Experiment with both settings to find the one that provides the most coherent bass response.
- TERPENCIL: Connects the wired remote bass level control.
