Simple trick actually..
1. Get a 9V "1N" type battery (the small rectangular general usage ones) and a connector to suit it with flying leads (bare wires). This shouldn't cost more than a few cents at an electronics shop. 2. Unscrew the OEM speaker and disconnect the factory wiring harness from it. 3. Momentarily "tap" the 9V battery leads across the speaker terminals. If the speaker cone moves forward when you do this, the + side of the battery is connected to the + speaker terminal. Likewise of the speaker cone moves backwards, the + of the battery is connected to the - speaker terminal. 4. Use your newfound polarity knowledge to work out which wire on the OEM adaptor is which :) Note: don't use anything more powerful than the battery suggested, and only hold DC current on the speaker as long as you need to (i.e. < 1 second). An old, partially discharged 9V battery is the best bet - a fully charged one will get the cone hopping pretty hard. Lower voltage batteries will also work, but the cone movement may be too small to be useful. |

One will probably have a black stripe on it and the other will be a solid color.

a black stripe would imply a negative...usually, although the in-car wiring isnt always setup like that...could be any number of colors, could even be 2 compleatly different colors going to the same speaker.
what exactly are you trying to figure out? what terminals are which on the factory speakers, or which wires are which in the factory wiring? |

factory speakers have already been replaced last year, now I need to upgrade again but I'm not sure if the actual speakers are well connected and the OEM harness is gone... would be helpful to know which wire/color is what, yes

it's very easy if you have a multimeter. Connect the wires of the meter to the speakers wires. if the meter display negative voltage, reverse the color of the connection. Therefore, the speaker wire connects to the red (positive) wire of the meter which is a positive output!

That would work for DC cheulki, but not for audio which is AC I'm afraid :(

I'm just curious.
If, for any reason, the positive and the negative of the speaker wires are hooked up the wrong way, will the sound play so bad that anyone could tell something is wrong? I just replaced the speakers this past weekend and just wondering that thinking it's installed incorrectly and I'm just not noticing it.

AudioVisual.pdf of the Yaris repair manual have all information. From the exact color of the wires.
I was just wondering "what happens if positive and negative are hooked up the wrong way". I did not mean I do not know which is positive and which is negative.

phase difference. One cone would move in while the other cone moved out. I recall reading something like that years ago. So, I would assume the sound wouldn't be as clean? You could also do a search on the internet for wiring speakers and in phase or out of phase issues, (I'm too lazy to do it now ) Of course, I would defer to the audio experts on here. |
