4.2 Hononga Waea
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.
Whakaahua 5: Whakatata 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.
- Hiko (BATT +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Papa (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Whakaka-Mama Mamao (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).
- Aratau Whakauru: 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.
- Tāuru Taumata-iti (RCA): Connect RCA cables from your head unit's pre-outs to the ampKo nga whakauru RCA a Lifier.
- Tāuru Taumata-Teitei: 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. Te whakahaere i te Ampkaikawe
5.1 Whiwhi Whakatikatika
Adjust the GAIN knobs for each channel to match the output voltago tō waeine upoko. Tīmata ki te whakanui i te iti rawa, kātahi ka piki haere mārire kia tae rā anō ki te oro e hiahiatia ana, me te kore he oro.
5.2 Tautuhinga Whakawhiti
The VADM4v2 features selectable crossover modes and variable filters:
