Motorcycle Amplifier

NSTE-4020 is a compact, stable, four-channel, full-range Class D amplifier designed for in-vehicle and outdoor applications, particularly for space-constrained users who demand high-quality sound and durability. Its compact dimensions of just 138mm × 96mm × 49mm make it easy to conceal and easily install, while also offering a wide range of placement options for motorcycles, electric vehicles, ATVs, and boats. Operating at 14.4V, each channel supports stable operation into a 2-ohm load, with a single channel delivering 20W RMS power with less than 1% distortion, ensuring clear and smooth sound quality. The NSTE-4020 features a fixed input sensitivity of 2V, compatible with standard audio sources, simplifying setup and lowering the barrier to entry. Dedicated TE waterproof connectors effectively prevent moisture and dust from intruding, enhancing system reliability in humid, dusty, or even lightly splashed environments. It is ideal for motorcycle audio upgrades, open-back vehicle audio systems, and other applications requiring high weather resistance.

NSTE-2120 2-Channel full-range class D power amplifier is designed specifically for in-car audio systems, motorcycle audio systems, and outdoor mobile audio environments. Combining outstanding power performance, robust protection, and installation flexibility, it's an ideal choice for users demanding both high-quality sound and adaptability to harsh environments. Its compact design allows for easy installation in tight spaces, making it particularly suitable for space-sensitive applications such as motorcycles, ATVs, and electric vehicles. The exterior utilizes a TE waterproof connector, and the overall system achieves an IPX4 to IPX5 rating, offering excellent water and dust resistance and stable operation in rainy, humid, or dusty environments. While the crossover also features a fixed configuration, its preset parameters meet the driving requirements of mainstream speakers, ensuring a frequency response range of 20Hz to 20kHz, achieving full-band sound reproduction and delivering exceptional performance from deep bass to crisp high frequencies.

NSTE-2045 is a highly efficient, compact, two-channel Class D power amplifier designed for audio systems such as motorcycles, electric vehicles, UTVs, and ATVs, which have strict requirements on size while requiring both weather resistance and sound quality. The output power per channel is 45W RMS (4 ohm load, 14.4V power supply), and the total harmonic distortion is controlled within 1%, ensuring clear and full sound quality, meeting the needs of daily entertainment playback and commuting. Its operating frequency range covers 20Hz to 20KHz, fully restoring the full-band sound effects, with excellent performance from low-frequency shock to high-frequency details. In terms of safety protection, the NSTE-2045 is equipped with overheating, overload, and short-circuit protection mechanisms, which can automatically cut off the power in the event of electrical anomalies or excessively high ambient temperatures, effectively avoiding equipment damage and extending the product life.
