2006 D-MAX speakers not working after installing double din

[coalroller82]

so my truck had a factory radio which seemed to work fine including the speakers horn and door chime. I bought a Kenwood ddx419 which was already wired on another silverado. so i asumed it would work fine. After plugging everything in and figuring out how to use it i was suprised to find out my horn, door chime, and all my speakers stopped working. I checked all my fuses and relays and they seem to be fine and working. I don't know whether its because the truck that i pulled the radio didn't have bose audio, or on-star. the radio functions properly but none of the speakers work. Please help me in this case. thanks!

Did either truck have bose, onstar, or both?
