In this paper we consider the global existence and nonexistence of solutions for
a Klein-Gordon equation with exponential type source term in a bounded domain. In the
framework of potential well, we define a functional, and by sign invariance of this functional
we prove the global existence of weak solutions in the case of high initial energy. Moreover,
we extend a finite time blow up result given in the literature.
