  In this article, we consider the stochastic wave equation on $\mathbb{R}_{+}
\times \mathbb{R}$, driven by a linear multiplicative space-time homogeneous
Gaussian noise whose temporal and spatial covariance structures are given by
locally integrable functions $\gamma$ (in time) and $f$ (in space), which are
the Fourier transforms of tempered measures $\nu$ on $\mathbb{R}$, respectively
$\mu$ on $\mathbb{R}$. Our main result shows that the law of the solution
$u(t,x)$ of this equation is absolutely continuous with respect to the Lebesgue
measure.
