You could remove the rear trim pieces underneath the rear seat and see if there is a plug there...If I remember it was just two wire black and white.
Here ya go...I believe the second picture in the first post is of the subwoofer plug. If you dont have the plug then you would have to wire your own...unless the headunit doesnt even have a connection for it
