From what I unserstand, no, you cannot hear the dvd through the sound system. However, can't you buy seperate speakers to hook directly to the dvd player? It would eliminate the cost have having the vehicle rewired, which could cause the warranty void. There are many ways to do, maybe it's something worth checking into.
I think this might work. One of my friends found a pair of fairly cheap speakers and he puts them attached with velcro to a cover that goes over the head-rest of the two front seats. That way, the speakers are on only when he is having the kids in the car and they are watching a movie. Otherwise, he takes them out. He avoided the wiring, since the speakers he found work with batteries, but also have an adaptor for the car. It was a fast and very easy solution for the problem when there are more than 2 kids!
