The WONDOM AA-AS32992 WPA2X20 is a compact stereo amplifier designed for outdoor, automotive, marine, and industrial applications requiring excellent resistance to harsh environments. Certified IP67, it is resistant to dust, weather conditions, and temporary immersion up to 1 meter deep for 30 minutes. Based on a 2x20W stereo amplification architecture, it supports both Bluetooth audio sources and analog 3.5mm AUX inputs, providing great flexibility of use. Its power supply accepts an extremely wide voltage range from 10V to 80V DC, allowing integration into vehicles, boats, agricultural equipment, and off-grid installations. Its fully aluminum enclosure ensures excellent heat dissipation while providing high resistance to vibrations and mechanical stress. The WPA2X20 also features Bluetooth disconnect and quick shutdown controls, secure Plug & Play connectors, and integrated protection against overheating, overcurrent, short circuits, and reverse polarity. Supplied with a waterproof connection cable and heat-shrink identification sleeves, it provides a reliable and easy-to-deploy audio solution for the most demanding environments.

Thanks to its fully waterproof and dustproof IP67-certified design, the WPA2X20 can be used confidently in humid environments or areas exposed to harsh weather conditions. It withstands rain, water splashes, dust, mud, and temporary immersion up to 1 meter deep for 30 minutes. This ruggedness makes it ideal for boats, off-road vehicles, outdoor installations, terraces, and embedded audio systems.

The WPA2X20 stands out with its extremely wide power supply range from 10V to 80V DC. This compatibility allows it to operate directly from numerous power sources commonly used in cars, trucks, boats, agricultural vehicles, and autonomous systems without requiring a dedicated voltage converter.

To suit every application, the amplifier offers dual audio connectivity with wireless Bluetooth input and a 3.5mm AUX input. Users can choose between a stable wired connection or convenient wireless streaming depending on the application. The quick Bluetooth disconnect and power-off functions also simplify the daily management of connected devices while helping to reduce power consumption.
