1. Power Connection (POWER): Connect a 6mm² (approx. 10 AWG) power cable from the vehicle's positive battery terminal to the amplifier's "POWER" terminal. Install a 30A fuse within 30cm (12 inches) of the battery.
2. Conexión a terra (GND): Connect a 6mm² (approx. 10 AWG) ground cable from the amplifier's "GND" terminal to a clean, unpainted metal point on the vehicle's chassis. Ensure a solid electrical connection.
3. Acendido remoto (REM): Connect a 0.75mm² (approx. 18 AWG) remote wire from your head unit's remote output to the amplifier's "REM" terminal. This turns the ampacende e apaga o activador coa unidade principal.
4. Speaker Connection (SPEAKERS): Connect your subwoofer(s) to the "SPEAKERS" terminals using 2.5mm² (approx. 14 AWG) speaker wire. Ensure the total impedance of the connected subwoofers is 2 Ohms or higher. Observe correct polarity (+ to + and - to -).
5. Audio Input (INPUT):
   • Entrada RCA: Conecta os cables RCA da saída de subwoofer da unidade principal á amplifier's "INPUT L" and "INPUT R" RCA jacks.
   • Entrada alta: If your head unit does not have RCA outputs, use the high-level input. Connect the speaker outputs from your head unit to the "HIGH INPUT" terminals (+L/-L and +R/-R).

6. Instrucións de funcionamento

Unha vez que amplifier is installed and wired correctly, you can adjust its settings for optimal sound performance.

6.1 Encendido inicial

After all connections are made, reconnect the vehicle's battery. Turn on your head unit. The amplifier should power on, indicated by an illuminated LED (if present).

• CROSSOVER (L.P.F. 35Hz ~ 250Hz): The Low Pass Filter (LPF) allows frequencies below the set point to pass through to the subwoofer. Adjust this to blend the subwoofer's output seamlessly with your main speakers. A common starting point is 80Hz-100Hz.
• CROSSOVER (H.P.F. 5Hz ~ 35Hz): The High Pass Filter (HPF) allows frequencies above the set point to pass. For subwoofers, this is typically used to filter out extremely low, inaudible frequencies that can waste amplifier power and potentially damage the subwoofer. Set it to the lowest useful frequency, often around 5Hz-10Hz.
• BASS BOOST (FREQ 35Hz ~ 60Hz, GAIN 0dB ~ +15dB): This control allows you to boost specific bass frequencies.
  • FRECUENCIA: Selecciona a frecuencia central para o realce de graves.
  • GAÑA: Adjusts the amount of boost applied to the selected frequency. Use sparingly to avoid distortion and potential damage to your subwoofer.
