2007 Chevy Avalanche, Full Bose Audio Replacement?

For anyone who has done one of these, I have an 07 Avalanche non-navigation but Bose system. I want to replace the head unit and all door speakers and add an amp but keep onstar and chimes. Which harness kit did you use, how did you bypass the Bose amp and did you grab the speaker wires from the output harness of the Bose amp?"ole blake"

The harness to use will be the PAC Audio BLU-GM29, but with an aftermarket 4-channel amp you will have to add an external speaker just for the on-star the signal will not pass thru RCA outputs of the aftermarket deck.
