Precision Power MPA700.4D 700W RMS ATOM Series Water-Resistant Class D 4-Channel Amplifier

In 2021, ATOM amplifiers adopt an adequate 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 relocated to the chassis’s leading edge for a more convenient, more appealing install. All pre-amp & crossover options are conveniently located on the backside. You might not notice 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.
