Thanks for the advice. I was finally able to trace the wires by getting the color from behind the speakers and finding them under the dash, ( your colors were the same as mine. no Connector) in any event to say the standard speakers are poor is high praise. I can now put in some better speakers. I am not an audiofile but I do want something I can hear while going down the road.
