An acoustic guitar is not dependent on any external device for amplification. The shape and resonance of the guitar itself creates acoustic amplification. However, the unamplified guitar is not a loud instrument. It cannot compete with other instruments commonly found in bands and orchestras, in terms of sheer audible volume.
Many acoustic guitars are available today with built-in electronics and power to enable amplification.
