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?

As Lennie said, as long as you are consistent which wire goes on which speaker terminal.

The only difference if you swap plane and striped between speakers, the difference is that the speakers will be out-of-phase. That is, if the speakers played the same note, one speaker would be moving outward while the other is moving inward.

I'm not sure one would be able to perceive that the phasing is incorrect.
