i'm building a 10 audio amplifier ,, i need part no. and data sheets for the mic and the speaker ??

 

This is the second forum you've asked this question in!, please only post requests in one forum!.

As for your question, it's too vague to answer, you need to provide far more detail - such as the specs of the microphone and speaker, what power supply is available - and probably what the intended purpose of it is.
