One reason could be overloading the input to the amp.

The opamp output can only swing to the rails or close to it depending
on the opamp.If your output signal is larger then your rail voltage
you get clipping.See here.

** More than one possible explanation exists - since the characteristics of
your " amplifier " have not been defined.

Define them now.
This question has been taken from the section "power amplifiers"

Saturation of the amp?
Over driving the input?
incorrect amp type ?
something wrong with the amp?
