installing a pioneer double din on a 06' Chevy Silverado with Bose and onstar...we have the right adapter,cd player is like new ....and everything is connected sound comes on for like 5-10 seconds then goes away....but cdplayer stays on.........whats weird on the harness adapter it has rcas instead of speaker wires to hook up to the cdplayer harness speaker wires...

any ideas?im sure its something simple
