I just got some more info from a friend... the a/v in/out connector on the back of the D3 that he has, has the same wires that I was talking about for my adapter.
The wires on the adapter are positive and negative for each speaker (i.e. positive front right speaker, negative front right speaker).
The wires coming out of my HU are stereo "front speakers" only a left and right channel. Is this a typical connector from the D3, can I get another adapter someplace.
Please let me know.
Thanks
Jeff
