Musway NX400.1

The Musway NX400.1 is an exceptionally compact mono Class D amplifier from the modern NX series, offering powerful bass reproduction with minimal space requirements. With up to 400 watts RMS at 1 ohm, this power amplifier is ideal for high-performance subwoofer systems and space-saving car audio installations.

Thanks to efficient Class D technology with an efficiency of up to 87%, the NX400.1 combines high output power with low heat generation. The high-quality aluminum enclosure measures just 89 x 41 x 125 mm and features an illuminated Musway logo behind a real glass window.

An adjustable low-pass filter, a subsonic filter, and a bass boost of up to 18 dB are available for custom bass tuning. The included bass level remote control allows you to adjust the subwoofer’s volume conveniently from the driver’s seat.

The built-in high-level inputs with EPS® technology also allow for connection to factory-installed car stereos. An automatic power-on function, start-stop compatibility, and low-noise IFT technology round out the features.
