TECHNICAL FEATURES
Atom amplifiers adopt the optimum 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 chassis's leading edge for an
easier, more appealing install. All pre-amp & crossover options are conveniently located on the
backside. You might not notice additions to the circuit board, including increased power supply &
output stage components & monoblock bridging capability. Installation of Atom amplifiers is unique,
using a mounting pedestal at each corner. The pedestals elevate the heatsink, improving airflow
around and under 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.
