Don’t let these little monsters fool you. The latest and greatest of Class D full range technology allows us to pack 10 pounds of KICK YOUR ASS in less than 2-pound chassis. Once regarded as “dirty power”, class Ds stable performance, thanks to high power capability, maximum efficiencies, and low tolerance components, rivals traditional full-range applications. Minimal power requirements, ultra-micro footprint, unbelievable sound quality, and easy install make Stealth amplifiers great for any car, motorcycle, boat, or off-road vehicle…

Using an Original or Factory Radio? No Problem, this amplifier is equipped with an Automatic Hi-Level Signal Sensing Turn-On. No need to run a remote wire turn on, this amplifier will detect the signal and turn on and off automatically. (Hi-Level Input only)
