Great Amplifier
I have owned many amplifiers. Steg, Focal, PPI, Clarion, Rockford Fosgate, Kicker, Orion (old hcca and xts series), a/d/s, Audison. This is one of the two best amplifiers in the under $200 price range for a 4 channel amplifier. It is overbuilt, puts out more power then listed, and does not add any coloration to the signal. The distortion is very quiet and barely noticeable. The only other amplifier that is a 4 channel under $200 I would even recommend is the Clarion.
