Hi John,
Our 10W Mini Amplifier http://www.electronics-lab.com/projects/audio/016/index.html provides 1.9W into a 6 ohm speaker at clipping with a 12V supply. It is a mono amplifier project.

Our 22W Audio Amplifier http://www.electronics-lab.com/projects/audio/006/index.html provides 6.5W into each 6 ohm speaker at clipping with a 12V supply. It is a stereo amplifier.

i forgot to tell that my speaker is branded sony.... it is use as satellite speaker in a component... in your 22W stereo amp... could i use both speaker left and right with the same rated impedance at once???

The 22W Audio Amplifier project can provide 6.5W to each of two 6 ohm speakers at the same time. But satellite speakers are small and might be damaged if 6.5W of bass gets to them since they are usually used for only midrange and high frequencies with a separate powerful subwoofer playing the bass. You might need a crossover circuit so that the satellite speakers don't have bass frequencies.
