    Maybe you could use them to power the speakers in your car.

    Or to amplify the signal in an FM transmitter(a real one) up to the tens of kilowatt level,so that the signal will be nice & loud for the FM receiver in your car.

    Seriously,though,this a silly question.

    Just Google for Power Amplifiers & you will find many references to the use of such amplifiers.

    If this is a formal homework question,surely somewhere in the course,you will have been taught about this.

    Power Amplifiers are extremely important in many aspects of Electronics,from mobile phones,to satellite Earth Stations.

    You use a power amplifier if you need to micro-step a stepper motor in a robotics application, or drive a coil in NMR ( nuclear magnetic resonance), MRI (magnetic resonance imaging) or EIT (electrical impedance tomography).
    It is required to drive the spindle motor and linear head seek motors in disc drives.
