NVX VADM4 v2: Compact, powerful 4-channel amplifier for cars, boats, and powersports

Upgrade your vehicle audio with the NVX VADM4 v2, a robust 4-channel Class D amplifier designed to deliver controlled, dynamic power across a range of settings. Its compact footprint fits behind dashboards, under seats, or in tight compartments, helping you build a vivid soundstage without sacrificing space.

Built with micro Class D technology, the module packs substantial output into a slim profile. The enclosure measures just 6.49" L x 3.3" W x 1.48" H, making it easier to mount discreetly while still providing ample headroom for clean, accurate sound. The marine-certified conformal coating guards the circuitry against moisture and humidity, extending durability in coastal environments or open-air setups.

Ease of use is baked into the design. LED power and protection indicators offer quick status checks, while a comprehensive four-way protection circuit guards against common issues like heat buildup and short circuits. The amplifier accepts balanced differential inputs or low-level RCA inputs for flexible integration with your existing head unit or processor.

Sound customization is a standout feature. Choose from FULL, HPF, or LPF crossover modes, and dial in high-pass and low-pass filters from 40 Hz to 400 Hz. With a wide frequency range of 20 Hz to 20,000 Hz, you can sculpt the character of your music to suit your space and taste. The 2/4-ohm stability supports different speaker configurations as your setup evolves.

Real-world use cases are where the VADM4 v2 shines: a four-channel setup can power a complete front-and-rear speaker array, while the flexible crossover network allows a dedicated sub with clean crossover points. For marine or outdoor rides, its durable build and compact size combine to deliver reliable performance on long trips or weekend adventures. While results depend on components and setup, the VADM4 v2 offers a credible path to richer, more immersive audio wherever you go.
