I have a friend that has a jensen in dash flip out screen dvd player installed, and when he plays a cd in the unit the radio continues to play in the back drivers side door. my first thoughtwas somethings wrond with the radio but everything functions like it should. so the next thing was maybe a crossed wire but we didnt take anything apart he had to leave to go offshore. then i also tought maybe each speaker has a built in crossover or something. but i really think something is installed wrong. but if anybody else has had this problem some insight would be good to get this thing solved.
