is there a way to connect my factory amp to tha d3?so that the est of my speakers can work.right now only the door speakers are work the trunk speakers (6x9s) arent and i think a pair of tweets on either sides of the center console.?!?!?! help plz cntrlvr79 or misfit

like i said before, none of my resources list an amplifier for the s-type. it basically has a ford radio, and they have on board power. what year did you say it was?

If there is an amp in the car, odds are it's under the rear deck. That is if it's an older jag anyway.
