Precision Power (PPI) A700.4D

ATOM amplifiers adopt the most exemplary Korean 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 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 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.

Little giant

Love the value (lots of power for the money), not so crazy about the plate over the controls.

This little thing does crank out real 100w x4 channels, as opposed to some others in this bracket that do not come close to advertised power. Sound is clean and deep, which belies low distortion and audiophile grade S/N ratio. The crossover controls are actually pretty accurate, to my surprise.

Have it mounted in the trunk of my Mustang DH, takes up very little room and drives the rear deck speakers and a dual voice coil sub. If nothing else it fixed the underwhelming performance of the B&O factory system.

Not so crazy about the controls, tiny and you must remove a face plate to get at them. Good for the long haul, but initially a pain as you fine tune the controls to dial it in.
