i have a 95 mazda mx-6 and it doesn't have a radio deck in it. just an empty din with a few wires hanging loose in it. one of the wires looks like an actual plug of some kind that would hook to the back of an audio unit. i'm trying to hook the speakers to a computer, so i'm guessing i have to get a converter for that plug to 3.5mm jack or something. maybe not? how do i do this? the computer is a Nokia 770 internet tablet if that helps at all
