Stereo Wiring, poitive/Negative? Options

[Cambo]

Yes, I'm not a stereo expert. Car has a Sony Explod deck and Explod speakers. Wiring harness has 2 wires for each speaker. One plain, one with black stripe. Which one is positve/negative?

Also, speaker has pins, one large with red wire going into the speaker, one small pin with black wire and a weird blue curcuit thingy inline? What's positve/negative on the speaker?

Thanks, all was already in car when I bought it but it was wired hillbilly style, lots of splices, crappy wiring etc. Replaceing wire, less spices, better connections etc. Can't afford new stereo/speakers right now so I'm trying to resurect the old stuff.

Oh, also found a two channel Alpine amp tucked up under the dash with a whopping 18 watts per channel, thing looks pretty old and it's tiny. Think it was a dealer install?

be consistent so the speakers will not be out of phase (whihc unless your ear is good you probably would not notice. All the stereo's I have wired used the white striped wire as your positve which in turn connects to red, negative would be your plain wire no stripe to black terminal. That 18 watt alpine may sound better than a new bonanza wattage blaupuinkt w/ leds and zoom whams..
