Is there a way to figure out which wire is positive and which is negative if they are not the standard colors? What happens if they are connected opposite unknowingly. Thanks for your help

The speaker leads in a 1995 ford windstar. I'm not sure if I have some of the wires connected wrong because some of the speakers break up at higher volumes. I've checked different sites for the color codes of the wires but every one says something different. Thanks

If the leads were wrong then the symptom would be lack of bass response due to out-of-phase signals to the two stereo speakers. Breaking up at higher volumes is usually attributed to either a too-low crossover setting for the speakers, or clipping of the amp due to improper gain setting.

A trick I learned a while back:
9 times out of 10 (all the time in my case)
If you flip the stock speaker over and have it next to the new speaker, line the terminals up together. If you see the wire from the car that connects to the left most lead on the stock speaker, it should connect to the same left side of the new speaker. And the right should connect to the right.
Out of the hundreds of speaker upgrades I have done, this has never failed.
Of course, most new car have clips that companies like Metra Electronics have a molex mate, so you don't have to cut stock wires.
This works I think because speakers are all built the same way (generally speaking, of course), regardless of factory or aftermarket design.
Hope this helps.
