With the main power IC TDA1554 Powered, operates this route to 22W. A few external components that support for the main component. Heat sink on the power IC is a must.
Components:
R1__________39K 1 / 4 watt resistor
C1, C2_______10uf 25V electrolytic capacitor
C3__________100uf 25V electrolytic capacitor
C4__________47uf 25V electrolytic capacitor
C5__________0.1uf 25V ceramic capacitor
22w_amp_TDA1554_Circuit
C6__________2200uf 25V electrolytic capacitor
U1__________TDA1554 Two Channel Audio Amp Chip
MISC________Heatsink For U1, Binding Posts (For Output), RCA jacks will (for input) This works best with 4 ohm speakers, 8 ohm operation, but do. This circuit has gone about 28 watts of heat, so that’s a good heatsink is required. The chip should run cool enough to touch the heatsink correctly installed.
Operated at 12 volts and about 5 amps at full volume. Small amounts consume less power and thus produce less heat. PCB is preferred, but universal solder or perf board will do. Keep lead length short.

stereo output ba yang power amp moh???,at wala ba yang destorsion???
It was nice to provide an image of PCB but you need to provide dimensions of the board itself. The picture was helpful in part layout and placement. Are PCBs available from some vendow?
Ha! Ha! Sorry ,i lose informations
