TSX Aux Radio Install???

[ssb]

I just purchased a used 2004 Acura TSX, with factory radio and navigation system. In all of our other cars, we have Kenwood excelon radios installed. I have taken out the equipment from the one that is going to be sold, including radio, amp, and sirius tuner. What I think I want to do is..Keep the factory radio installed.. It is all tied to the Navigation and air conditioning system. Is there a way you know of, I can install the Kenwood(single din radio) as a second radio. That way I would be able to use the Kendwood CD changer and the sirius tuner I already have.

Simply put, I want to install the Kenwood radio as an accessory wired to the factory speakers. I will only use one radio at a time, and I don't really care if the AM/FM antenna can be plugged into the Kenwood.

Any advice on a harness and intallation??

You need to custom build a relay system
