I just got a XO vision XO1900 and wired it all up, but i get no sound out... I didn't use any kind of adapter or converter or anything, i just used the diagrams i had to connect the wires.

its really frustrating. now i have no music any help is appreciated.

Thanks

 

so i figured out the problem. the stock amp ( i have premium sound) was feeding back a signal to the head unit and shut off the stereo outputs. so i cut out the stock amp, and now it all works great
