what are the + and - wire colors for the front speakers?

Thanks

 

To determine the polarity, I use a 9v battery and the factory speaker. Run a wire between the + on the battery to one terminal on the speaker, and another wire from the - on the battery to the other terminal. Watch the speaker cone - if it pushes out, the terminal hooked to the + on the battery is the positive lead. If the cone pushes in, the terminal with the - wire is the positive lead. Then all you need to do is look at the factory wires to determine which is which. Right and left rear speakers use different color coded wires, so if you use this, you will have to pull both rear speakers to get it right.
