The 4 channel SS4a may be one of the most versatile amps we’ve ever offered. With 160 Watts delivered into 4 channels at 4 Ohm and 240 Watts of power at 2 Ohm per channel, the SS4a can be used in high output 4 ch systems, drive 3 ch systems with close to 500 watts to the sub and 240 per channel to the mid/high speakers. In bridged stereo mode, the SS4a delivers close to 500 Watts per channel. The new discreet, full range class D circuit is groundbreaking in its compact use of space and low current draw while delivering crystal clear sound.

For the SS Series the main design focus was to pack as much full-range stereo output capability as possible into as compact of a chassis as possible. We utilized discrete circuit class D technology for ultra low distortion levels that rival class AB designs. The resulting amp is capable of driving multiple driver mid-range and tweeter arrays while consuming less current, taking up less space and delivering more power.
