Mosconi Atomo 2

The Mosconi Atomo 2 is an extremely compact and powerful 2-channel Class-D amplifier that delivers impressive output power despite its minimal dimensions. With 2 x 100 watts RMS at 4 ohms or 220 watts RMS in bridge mode, this power amplifier is ideal for a high-performance upgrade of existing car audio systems where installation space is limited.

Thanks to its integrated high-level and low-level inputs, the amplifier can be used with both factory-installed and aftermarket radios. The automatic power-on function via the high-level signal (BTL), flexibly configurable inputs, and the built-in high-pass and low-pass filters enable versatile integration. High-quality Molex connectors and the black anodized aluminum housing round out the compact design.
