We obtain a faithful representation of the twisted tensor product $B\otimes_{\chi}A$ of unital associative algebras, when B is finite dimensional. This generalizes the representations of [C] where $B=K[X]/$, [GGV] where $B=K[X]/$ and [JLNS] where $B=K^n$. Furthermore, we establish conditions to extend twisted tensor products $B\otimes_{\chi}A$ and $C \otimes_{\psi}A$ to a twisted tensor product $(B\times C)\otimes_{\varphi}A$.\\
