[QUOTE="Vestax, post: 693318, member: 556319"] You test speaker leads with A/C voltage while the radio's on but there's an easier way: Make sure your radio's off. First you test for continuity. There's a symbol that shows something like a sound wave. If you put the test leads together, it will make a beep sound. Now if you stick those test leads on a speaker, you're basically going to have continuity through the voice coil. You'll hear a beep sound when you found the right pair. So you go through each wire and pair them up. Once you find a pair, test for ohms. You should get 4 ohms. When you find all 4 speakers, and you want to find which one is rear or front, you can use a 9 volt battery to pop them. Or fade it to the rears and test for A/C. You can basically hook up a LOC while the speaker is still plugged in. This is how installers do it in a shop. However if you have a factory amp, that's a different story. Let me know if you do.
