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.

NSLBM-2150 is a high-performance, two-channel, full-range Class D car amplifier designed for users who demand powerful sound quality and exceptional protection. Its IPX5 waterproof rating and rugged mechanical construction (ME structure) ensure stable operation in harsh environments, making it ideal for outdoor and in-car audio system upgrades. The NSLBM-2150 delivers 100W RMS power per channel into a 4-ohm load, increasing to 150W RMS into a 2-ohm load, with sub-1% distortion, delivering a clear, rich, and dynamic audio experience, meeting the dual power and sound quality demands of various audio systems. The product features a pre-wired pigtail harness, simplifying installation and reducing wiring complexity. A DIP switch control panel allows for flexible crossover mode selection, and a built-in low-pass filter (LPF) with a selectable 120Hz or 80Hz setting allows users to adjust the frequency response and optimize sound quality based on their speaker configuration.

NSXP-2120 is a high-performance, two-channel Class D car amplifier designed for in-car audio systems that demand clear sound quality and space-saving features. This two-channel Class D amplifier delivers 2 x 70W RMS power into a 4-ohm load and 2 x 120W RMS into a 2-ohm load, with total harmonic distortion (THD) kept to less than 1%, ensuring pure, dynamic sound. It's ideal for driving mid-range and high-frequency speakers, delivering a more three-dimensional and natural musical performance. It can be conveniently installed concealed under a car seat or in the trunk, minimizing space and providing greater installation flexibility for limited interior space.
