I just read something bout this but i have a different problem. I have the cord with two males going to the imput on my pioneer head unit from my 1/8" that goes to my mp3/laptop. The problem is when i try and play music, it only comes out of the front two speakers. i have NO controll of anything on the head unit. Can somone send me a link to what i need or maby im useing the wrong cable? Thanks alot, Eric
