This Schematic use IC AN374, this is mono amplifier and have output speaker 1 W with impedance 8 Ohm . Supply need 8Volt to 16 Volt , this Schematic you can use current Voltage 12 V. And better use the stabilizer with 7812 let the voltage stabil. The Effect will be on the sound so smooth. See this Schematic below  and see datasheet IC AN734 : Datasheet IC AN374 Vcc                = 8-16 V Pout               = 1 W RL                  = 8 Ohm Ft                   = 50hz - 17Khz Icco                = 12 mA Package         = SIP2-10 Manufactered = MATSUSHITA

Description for this Schematic : Power Supply need 16 to 34 Volt , this is very beautiful voltage because with voltage 16 -34 Volt will  be strong to make a loud sound. IC need AN272 ,this ic no similarities. You must use this IC. Ouput speaker Mono , with Power 5W and Impedance 8 Ohm.

This is a simple circuit schematic, you can string up this circuit easily. You just need IC AN5260 with some components such as , Condensator Electrolit , Resistor , Ceramic Condensator . Schematic require voltage 12 to 26 Volt . And i use current voltage of 12 volt. Its nice sound , smooth , and low noise amplifier. You want to try this schematic ? . See this schematic below : Datasheet IC 5260 Vcc                = 12-26 V Pout               = 6,6 W RL                  = 8 Ohm Ft                   = 30hz - 18Khz Icco                = 60 mA Package         = SIP2-11 Manufactered = MATSUSHITA

Schematic Description : This Circuit Require voltage 12 -26 Volt. Good Voltage use is 16 Volt , Because its not too small and not too big Voltage. If use voltage that is to large it will quickly damage the IC. And if use voltage that is to small it will make less than maximum sound output.

This Schematic Require voltage 9 - 18 Volt. Good voltage for this schematic is 12 V. This is Mono amplifier with output 5,5 Watt and impedance 8 Ohm. You can make this Circuit easily because i give simple and clear scheme.

This schematic very suitable applied on small speakers. Because the maximum output is 3W and the minimum voltage is 12 Volt  , this will make speaker does not damage quickly. If you use speaker with impedance 8 Ohm , you must make parallel circuit speaker don't use series circuit.
