i have a 99 Isuzu Rodeo, and I went to replace my factory speakers. I pulled the old ones out, and found that the previous owner had already replaced the speakers. BUT they cut the harness to do it.

The obvious way would been to look at the old speaker, but I am a little past that point.

Can any tell me how to check the polarity of the wires? Which is positve, which is negative?

Oh yea, I tried to use the search button, but because my wife keeps telling me I am retarted I am starting to believe her.:eek:

Take an ordinary battery C or D will work fine and tape one wire to the + side and one to the - side. You now have a phase/polarity detector. In case you don't know what to do with it, touch the wires quickly but (dont keep them touching) from the battery to your speaker wires and pay attention to which way the cone moves. When you see the cone move inwards first, you know that you have the correct polarity.
