I am very interested in installing a sub into a center console but first I have to get the console. I drive a 2003 SE without a center console. I have seen the factory ones online and also have seen the Tuffy rear half consoles. The question I have is how hard is it to instal a center console when one did not come from the factory. And will the rear half Tuffy one work since the literature says it is a replacement for the factory one, which I do not have? Thanks in advance.
