Product Description

ATOM amplifiers adopt the finest class D performance, reliability, and footprint of the original ATOM and iOn platforms. At first glance, you’ll notice several key improvements. Atom’s signal inputs, power/ground, and speaker connections are all relocated to the leading edge of the chassis, for an easier, more appealing install. All pre-amp & crossover options are conveniently located on the backside. What you might not notice are additions to the circuit board, including improved power supply & output stage components, & monoblock bridging capability. The installation of ATOM amplifiers is unique, using mounting pedestals at each corner. The pedestals elevate the heatsink, improving airflow around and underneath the chassis. Additionally, rubber grommets under and inside each pedestal electrically isolate the amplifier chassis from the vehicle chassis, reducing the potential for ground loop noise.
