We have a built in DVD player in our Town and Country mini van for the kids to watch in the backseat.It comes with wireless headphones for backseat viewing so the driver can listen to the radio on the speakers. Only problem is my 2 year old twins can't work the headphones. Is there an alternative like ir wireless speakers to set in the backseat. I don't mind hearing their movie on an extra set of speakers. I don't need ones that need to be installed. I could just set them on the armrests or the floor in the back. Also there are 2 RCA spots in the DVD player upfront. Is there speakers I could plug into them or would that not work? Thanks for any ideas.
