Need some input. I have a 04 CS with the Bose system. I'm not interested in running all new wires and speakers, but I have a Kenwood DNX7100 from my old SUV that I want to install. Can anyone tell me if the Gateway 500 can be used to hook up this head unit, thus using the factory amp and speakers ? There is not much info on the web page, and the aux. RCA in's look like its only one channel. Thoughts ?
