I just purchased a new Kenwood hu and I am planing on installing it this weekend along with the Sirius receiver that I have. My question is, is there a way for me to use the factory sirius antenna? It has 2 connectors, and my receiver only has one input for the antenna. The guy at the local shop says he can use the factory antenna, but I do not want to pay to have it done if it is somewhat easy to do and I can manage it. If anyone knows how to make this work please let me know.
