Perhaps the surround amplifier circuit below is an interesting circuit is made. For, making easy just by using the IC and electrolytic capacitor added 1 , we already can hear the strains of music with sound ( Front Left ,Right and surround Right , Left. In addition to listening to music , this amplifier is also very suitable for gamers who want good sound quality.
Minimum voltage requred 9 volts and maximum of 15 volts. Power Output of each speaker 10 Watt with 4 ohm impedance.
