Making Surround Amplifier TDA7386 4 Channel

Surround Amplifier TDA7386 4 Channel its actually took from circuit power amplifiers that are in car Head Unit. I apply for a home room, almost the same as a home theater. I added with a homemade subwoofer. Making subwoofer you can see here: Subwoofer speaker and amplifier project 

Surround amplifier using TDA7386 is very cheap just need some component. You just spend money about $2 to make this amplifier. For the circuit schematic power amplifier you can see below:
