POWER OUTPUT NOTE: A power birth certificate is included for each amplifier. SD amplifiers are conservatively rated and will exceed their RMS power rating shown here. All RMS power ratings and measurements are at 14.4 volts with no more than 1% THD. SD800.4 and SD1100.5 feature ADAPT technology which provides the same power output from 11 to 15 volts with music material.
