I'm afraid you're in the same boat as me and out of luck. The original thinking was that you could replace the HU keeping the Bose amp & speakers, and based on that I bought an AVIC-D3 unit and installed it last Saturday. When I finished I could not get sound from the speakers at all. I thought it was the remote turn on wire (which is the solid white wire incidentally), but I had that connected and it was getting 12v, still no sound. Now in reading more, it appears that this Bose setup is different from most others, and the processing is done in the amp (notice the factory wiring only has left & right, not front, back, center etc, that's done at the amp level). I think we're going to have to bypass the amp, but I'm hoping I can take my wires from the HU and tap the wires coming out of the amp versus running all the way to the speakers themselves, but I'm still researching that. I have a diagram of the Bose amp output wires, pm me if you want a copy. If you are able to make it work with the Kenwood running to the Bose amp lmk, as I'm not aware of any way to make that work.
