Hey guys. i am currently designing an amplifier that will drive a speaker. But i am having a hard time in finding the best suitable BJT to use. I finished my pre-amplifier using a MPF102 and got a 1.56V output.

My project is to amplify a microphone signal so that it can drive a 2-watt or 4-watt speaker.

I've finished my pre-amplifier and i would like to know the suitable BJT for this project.

THANKS!
