Product Description

NSM-2020 is a miniature, two-channel Class D car amplifier measuring just 110mm (length) x 92mm (width) x 45mm (height). This significantly reduces installation space and is ideal for installation in confined areas such as under the dashboard, next to seats, or other discreet locations, while still delivering excellent performance. Its wide frequency response, covering 20Hz to 20kHz, faithfully reproduces rich details from bass to treble, satisfying the needs of a wide range of musical styles. The amplifier supports high- and low-level input switching for robust compatibility, making it easily compatible with both original audio sources and external devices. A signal-sensing function enables automatic power-on, and a built-in 12V remote output facilitates control and integration with other devices.
