My problem is that I can barely hear movies during car rides. I think that it is mainly due to highway noise. The DVD is being played through an Xbox. The yellow part of the RCA cable is going directly into a 7" LCD. The red and white parts of it are going into a seperate cable that joins the two into a single audio cable to which I pulg my headphones into. I have thought of a possible way to solve my problem. I could get noise-reducing headphones, however I am unsure as to whether they would cancel out enough of the highway noise for me to be able to hear. What do you guys thing? Would this work? Any other ideas? Is there some device that would just allow me to increase the volume? Thanks.
