getting sound from xbox to speakers??

ok i got a pioneer deh-7700mp cd player and im hooking up an xbox. i have 3 sets of preouts front, rear, sub. when i put them in the front output only the front plays but i cant control the volume its either on or off. how do i get sound to all my speakers and still control the volume?? thanks

you need an fm modulator

i forgot to mention that it did that when i turned it to aux. then when i turned it back to fm it would still have sound from the xbox over the radio. i crossed my rcas the white one to the front output and the red one to the rear and got sound to all my speakers but couldnt control the volume.

First, the preouts give output, not input, so the fact that you are hearing sound is screwed up but that is pioneer for you, junk. Next, there is an adapter, i believe it is a cdrb10 or CDRB20, one is cheaper and that is the one you would need. You hook that up to your cd changer plug and turn aux on and that will give you sound
