i have designed a circuit BUT i dont know if it would work in real life. it works fine simulated and gives a voltage gain of 10 - is this enough? the circuit is atached, i have doubts that i will work in real life and i would like to know what is wrong and how to sort it out,

what would the distortion be on a circuit like this would it be ok for a subwoofer?

how much power will it output?
how can this be increased?
