Hey guys i am going to install built in DVD headrest monitors into my 2007 touring prius. I have posted questions about this before, but want to know if anyone has detailed info on how to install these myself. Ive been told there is an amp under my drivers seat where i can do all the wiring, but im not sure & dont want to screw things up. If anyone knows how to do this or has a wiring guide or anything like for this, that be real useful. Also, if anyone knows how to get the seat back off to feed the wires down, let me know that as well. I have the leather interior & the seat backs seem seamless. & it if it helps, its the power acoustik HDVD-9 model twin monitors.
