We will be purchasing a 2007 Pacifica Touring that has the 6 disc dvd player and noticed it had the audio/video outputs in the dash. What is a cheap way of putting some headrest monitors in or just getting some dual monitors that mount around the headrest? Everywhere I look they are over $1k and/or have the dvd players in the monitors already which I don't need.

 

those are input, not output. either get the strap-on with the players embedded, or you can find my old tutorial here on how to install headrest monitors from (almost) scratch.
