after installing my I-VES in a '99 LX we find it difficult to hear the movie while sitting in the 2nd row, unless we blast the van audio volume which blasts the driver. my 2 yr old in the 2nd row seat will not leave the head set on, thus we use the van audio system. anyone have any ideas on how to add speakers to the 2nd row seat area so I can jump in on the back speakers which will allow me to fade the audio to the back so the driver is not blasted by the front speakers. I was thinking sliding door speakers but not sure if it can be done and what size. any ideas?
