Are the doors prewired for speakers

I have a 1997 Grand Voyager, It was not bought with the Infinity stereo system but i later purchased the stereo and was wondering if the doors are prewired for the speakers? is it possiable to wire the doors for speakers. thanks

The doors are more than likely NOT wired for the Infinity speakers. The Infinity stereo speakers required a harness different then the factory stereo. You can run new wiring to the doors that will support the better speakers. Find out first which wire does what going to the stereo.
