As seen in the design, the only active component is an integrated circuit TDA7386, SGS-Thomson. It provides four channels of amplification from a 12v source. The DC input is blocked from 0.1μF capacitor. STBY mute control terminal and may or may not be implemented, is up to you. Output is symmetrical, so there is no speaker terminal is grounded (both amplified).
