Two-channel power amplifier can be collected on an inexpensive integrated circuit TDA1555Q. This is a very simple scheme, which is able to emit output power up to 22 Watts for each channel. To power the chip requires a DC voltage source is 6-18, which is able to maintain a current not less than 4 a. Chip TDA1555Q you must ensure a good heat sink. 
The main technical characteristics of IC UMZCh TDA1555Q are presented in the table.
