It will amplify the audio signal to high power. Make your own computer speaker system. However the most commercial power amplifier ic has maximum fix gain around 200 times lm386 that far from 1000 times voltage gain and the problem when you make high gain amplifier is the high frequency roll off problem. This could be broken down into the blocks like the audio amplifier system.
