[QUOTE="ahole-ic, post: 6928762, member: 619324"] I don't know what settings yours has. Usually it will be 20, 200, and 2000. You would want to be on the 20 setting. Then you touch the leads making sure your fingers are not touching metal (because this puts another path in parallel and slightly drops the reading) to each individual voice coil + and -. Write down the reading for both. If it jumps around a little that is normal. Now, wire both + together and both - together. Take a reading from each of the joints you just made. Now, you are reading DC resistance. This is not how your subs are rated. They are rated in AC impedance. What does this mean? It means that what you are testing for is not exactly what we are using. Why? Well for your speaker to reproduce music, it has alternating current or AC pass through it. The same resistor in an AC circuit will not have the same effect on the current in a DC circuit. For this reason we call resistance on DC "resistance" and resistance on AC "impedance". Impedance can be measured, but not with your little meter. So, what did your measurements tell you? They told you that your voice coils were good. That's about it. [/QUOTE]
