Audio Amplifier

Hey, i have been tying to make a few amplifier models for 8ohm speaker, there are probabily more then a few mistakes but i am at pretty confused state just tried to multistage my a class amplifier woth another transistor with diffrent biasee versions. It would be amazing if you guys leaved a few comments or share a few information to how to make cascade or multistage or whatever confugration can be done i feel lost at amplifiers cause i dont know where to start how to design 10x gain amp or how should i add another system to this system etc. I passed my class at this year how to analysis (dc and ac) bjt to fet to mosfet transistors it is easy to analysis on paper with given values but cant design even a simple amplifier.
