The SS2b utilizes discrete, full range, class D circuitry to cram over 420 watts of output power into a tiny 6.9″ x 6.9″ x 2″ chassis. The size allows it to be installed almost anywhere; while the output power allows it to be used for a wide array of applications. This is the perfect two channel amp for driving component sets, tweeters, coaxials, or VO style speakers. Equipped with adjustable high pass(20Hz-5kHz) and low pass(50Hz-5kHz) filters you can easily match the SS2b to the connected drivers. Some other sweet features are the stereo RCA outputs for daisy chaining amps, set screw speaker and power terminals, remote gain control with clipping indicator, and panel mount RCAs.
