Funny to see this. I just finished (well work in progress) an install on my 91 Explorer. It had like the Taurus the factory amps and the like. I had chosen to keep the factory amps. I had upgraided the head unit and now all the speakers/ sub. Just go and get the right adapter that uses the amp.

I'm very much enjoying the result and it cost much less than new amp wiring ect.
