2 X 20 Watt Car Amplifier

This is a very simple circuit power amplifier with IC LA4440. This circuit is a circuit the first time i learned to make a power amplifier. Power output 2 X 20 Watt with stereo speakers. Minimum Voltage 9 Volt and maximum voltage 24 V. The Circuit is also very easy to make. For novices , this circuit is suitable for use . The material is also readily available at electronics store. 
See schematic below :

The Speaker are matched with woofer speaker with impedance 4 Ohms. And voltage can be stabilized with IC 7812 but must be reinforced such us transistor.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.
