No idea what the problem is then.

Thanks for your help.

That way you can connect it to your standard headunit preouts. I'm sure this has been done before on these cars. I would do some more research.

The other option is run speaker wire from your new headunit to the rear speakers, or install a small amp.

Yeah I told you this already! I said you need an adapter cable that would convert to RCA cables that would plug into the rear channel of your new head unit. Then I said Crutchfield supplied the adapter cable when I bought the head unit from them. This is the one they sent me:

Don't know for sure if it will work with your car, but my point is that they should have one available for you to purchase.
