Ok guys I am looking at upgrading the stereo gear in the Dmax. I am looking to put in a indash DVD/Nav unit, I like the Pioneer and the Kenwood. I just need to make sure that they can be hacked/ wired so that the DVD can play while driving. ITs for my kiddo in the back center seat. Next i want to add a couple subs. I am guessing that shallow mount will be the way to go, but know nothing about that stuff. The truck has the bose system, and not looking to change out any of those speakers at this time. Basically need the subs and video/ Nav. Lets hear your ideas.
