With features like quick-disconnect harnesses, low-level RCA inputs, and signal sensing turn-on, the MAA4.400 ensures easy installation and reliable performance, even in the tight confines of a motorcycle fairing.

The ATOM MINI Digital Amplifier delivers high-efficiency Class D performance in a compact chassis, making it ideal for motorcycle audio systems where space and power efficiency matter most. With impressive power output and rugged construction, it's engineered for riders who demand clean, distortion-free sound at any speed.

• [HIGH-OUTPUT CLASS D POWER IN A MINI FOOTPRINT] Despite its compact size, the ATOM MINI delivers 100W x 4 RMS @ 4Ω and 150W x 4 RMS @ 2Ω, offering enough headroom for loud and clear audio on the road. Its Class D topology ensures thermal efficiency, even during long rides.
• [ULTRA-COMPACT SIZE FITS TIGHT SPACES] Measuring just 9.25″ x 5.375″ x 1.875″, this amplifier is designed for tight installs inside fairings, saddlebags, or under seats. The small form factor enables discreet integration without compromising performance.
• [BUILT FOR MOTORCYCLE AUDIO ENVIRONMENTS] The ATOM MINI is vibration-resistant and thermally stable, designed to perform under the stress of riding conditions. Whether powering fairing speakers or a full 4-speaker setup, it maintains audio clarity at highway speeds.
• [OPTIMIZED FOR CLEAN SIGNAL DELIVERY] Each channel delivers stable, low-distortion power with ≤ 1% THD+N at 1KHz, ensuring accurate signal reproduction. This allows factory or aftermarket speakers to operate at their full potential without clipping or compression.

The ATOM MINI Digital Amplifier is the go-to solution for motorcycle audio upgrades where space is limited but performance can't be compromised.

ATOM MINI amplifiers adopt the most exemplary Korean Class-D performance, reliability, and this compact footprint fits inside your motorcycle’s fairing.

At first glance, you’ll notice several key improvements. All pre-amp & crossover options are conveniently located on one side of this amplifier, while quick-disconnect connection plugs for power and speakers outputs are on the other. You might not notice additions to the circuit board, including improved internal power supply & output stage components. We know you want it loud…
