Sound out of headphones only?

[zero2sixty]

I have an 05 Denali that I bought as a theft recovery with no head unit or amp in it. Put a new kenwood in and a factory bose amp. Now I only have sound out of the headphone jack. I have sound coming out of the back of the head unit. I an using PAC RP5-GM11 GM Class II radio interface to hook it all up. I also noticed that the wiring for the head unit to PAC has you hook up a blue wire for a remote wire but when I follow what I believe to be the remote to the factory harness connection there is no wire there to continue on if that makes any sense.

Any ideas?

These trucks use a data bus turn on. Harness should have a blue/white wire leading into the rp5.

Being that you have a Denali it more than likely has the LUX sound system in it. If you replaced the missing Bose amp with a LUX model it takes a special adapter/converter to interface with it. If you replaced it with a non LUX Bose amp you'll have to rewire the harness that plugs into the amp.
