4.2 conexiones de cableado
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.

Figura 5: Primer plano view of the power input and speaker output terminals on the NVX VADM4v2 amplifier. Connections include GND (Ground), REM (Remote Turn-On), +12V (Power), and speaker outputs for CH1-CH4.
- Potencia (BATT +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Tierra (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Encendido remoto (REM): Connect to the remote output of your head unit or an ignition-switched 12V source.
- Speaker Outputs (CH1-CH4): Connect your speakers to the corresponding channels. Ensure correct polarity and impedance matching (2-4 ohms stable).
- Modo de entrada: Select between 2CH or 4CH input mode based on your head unit's output.

4.3 Input Signal Connection
The VADM4v2 supports both low-level (RCA) and high-level inputs.
- Entrada de bajo nivel (RCA): Connect RCA cables from your head unit's pre-outs to the ampentradas RCA del amplificador.
- Entrada de alto nivel: If your head unit does not have RCA outputs, use the provided high-level input harnesses to connect directly to your head unit's speaker outputs.
5. Operar el Ampmás vivaz
5.1 Ajuste de ganancia
Adjust the GAIN knobs for each channel to match the output voltage de su unidad principal. Comience con la ganancia al mínimo y auméntela lentamente hasta alcanzar el volumen deseado sin distorsión.
5.2 Ajustes de cruce
The VADM4v2 features selectable crossover modes and variable filters:
