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?
