my 10 disc changer spins discs, wired-in controller works properly and shows the changer working properly, however I don't know how to make it play through the speakers. I have a factory BOSE CD/TAPE/fm/am stereo and I haven't for the life of me a clue how they work together. It was in the 93 Maxima when I purchased it four years ago and have never really cared if it worked or not, I just used the in dash CD player. Just curious. THANKS
