4.2 Ukuxhunywa kwezintambo
Refer to the wiring diagrams below for proper connections. Ensure all connections are secure and insulated.
Umfanekiso 5: Vala-up 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.
- Power (BATT +12V): Connect to the positive terminal of the vehicle's battery via an appropriate fuse.
- Indawo (GND): Connect to a solid, clean metal point on the vehicle's chassis.
- Ukuvula Okukude (i-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).
- Imodi yokufaka: 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.
- Okokufaka Okusezingeni Eliphansi (i-RCA): Connect RCA cables from your head unit's pre-outs to the ampokokufaka kwe-RCA ye-lifier.
- Okokufaka Kwezinga eliphezulu: 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. Ukusebenza kwe Ampokokuphila
5.1 Thola Ukulungiswa
Adjust the GAIN knobs for each channel to match the output voltage of your head unit. Start with the gain at minimum and slowly increase until desired volume is achieved without distortion.
5.2 Izilungiselelo ze-Crossover
The VADM4v2 features selectable crossover modes and variable filters:

7. Ukuxazulula izinkinga
| Inkinga | Imbangela Engenzeka | Isixazululo |
|---|---|---|
| No Power / Protect LED On | Blown fuse, poor power/ground connection, remote wire disconnected. | Check/replace fuse, verify power/ground connections, ensure remote wire is connected and receiving 12V. |
| Akukho okukhipha umsindo | Incorrect input connections, speaker wires disconnected, gain too low. | Verify RCA/high-level inputs, check speaker connections and polarity, adjust gain settings. |
| Umsindo Ohlanekezelwe | Gain set too high, incorrect crossover settings, speaker impedance mismatch. | Lower gain, adjust crossover filters, ensure speakers match amplifier's impedance rating. |
| Ampi-lififier Ukushisa Okudlulele | Insufficient ventilation, impedance too low, prolonged high-volume use. | Ensure proper airflow, check speaker impedance, reduce volume or allow cooling. |
