5.2 Connexions de cablejat
Refer to the diagram below for proper wiring connections. Ensure all connections are secure and insulated to prevent short circuits.
Figure 5.2: Rear panel showing power, ground, remote, and speaker output connections.
- Power Input (+12V): Connect to the positive terminal of the vehicle's battery using an appropriate gauge power cable (e.g., 4-gauge for 1200W). Install an inline fuse (not supplied) within 18 inches of the battery.
- Terra (GND): Connect to a clean, unpainted metal surface of the vehicle chassis. Ensure a solid ground connection for optimal performance and safety.
- Remot (REM): Connect to the remote turn-on output of your head unit. This signal turns the ampengegueu i apagau l'activador amb el vostre sistema d'àudio.
- Sortida de l'altaveu: Connect your subwoofer(s) to the speaker output terminals. Ensure the total impedance of your subwoofer(s) matches the amplifier's capabilities (1 Ohm mono).
- Entrada RCA (INPUT): Connect to the RCA pre-out of your head unit. If your head unit does not have RCA outputs, use the High Level RCA Inputs.
- RCA Output (LINE OUT): Provides a buffered signal for connecting additional ampaixecadors.
- Port de control remot: Connect the included remote bass control.

Un cop instal·lat, ajusteu el ampConfiguració del lifter per a una qualitat de so òptima.
Figure 6.1: Top panel showing input level, crossover, bass boost, and phase shift controls.
- Input Level (GAIN): Adjust this control to match the output voltage of your head unit. Start at minimum and slowly increase until you hear distortion, then back off slightly.
- Filtre subsònic (HPF): This filter removes ultra-low frequencies that are inaudible and can damage your subwoofer. Adjust between 15Hz and 40Hz.
- Lowpass Filter (LPF): This filter allows only frequencies below the set point to pass through to the subwoofer. Adjust between 50Hz and 150Hz.
- Intensificació dels sons més greus: Provides an adjustable bass emphasis at 0dB, 6dB, or 18dB. Use sparingly to avoid distortion.
- Canvi de fase: Adjust between 0° and 180° to ensure the subwoofer's output is in phase with the rest of your audio system, preventing cancellation.
- Control remot dels baixos: Use the wired remote to conveniently adjust the bass output level from your listening position.
