Damping factor is a measure an amplifier's ability to control the motion of the loudspeaker cone after the signal disappears (EMF). The damping factor of a system is the ratio of the loudspeaker's nominal impedance to the total impedance driving it. The higher the resistance the better control. Some amplifiers have that specification listed, keep in mind higher numbers aren't always best, you dodn't want too much damping, nor do you want too little. On home amplifiers of good cailbre I consider anything between 60-70 very nice.

I heard there was a certain loss of damping through the wire .. is that true? If it was true, then wouldn't you think that a PPI amp for instance with a damping of >500 would be much better than an amp with a damping of say 150? Audiophyle says anything >50 is all you need ... but if the wires are reducing the effective damping then wouldn't it make sence that the more damping in the amp the better and that in the end it would make a difference?

I heard that to calculate it you just measure the voltage output with no load and after you measure it with load and you substract the first result with the second result then you divide the answer by th voltage with no load...
Ex : no load : 45.00 volts RMS : with load : 44.50 volts RMS
45-44.5 = 0.5
45/0.5= 90
The damping factor is 90
This is the facility for the amp to hold his output voltage with and without load... If your amp just drop of 0,001 volt when pushing out 50volt this a really good amp...
50.000 to 49.999 volt... with load.. you see..?

There is a slight loss of overall dampimg through the wires since they have resistance. Since almost all car audio fanatics use oversized power wire, don't worry about it. Chances are if an amp has a damping factor of 50, you will hear all the other inferior specs...distortion, slew rate. Main point is, if an amp sounds good, it is good.

I believe what may referred to above has to do with MFB (Motional FeedBack) technology that MIT wires have. It's meant to reduce the feedback produced by the speaker, allowing the amplifier to perform as best it can. Although there are standards for testing amplifiers, keep in mind these tests are on "resistive" not "reactive" loads, in many cases the weighting method used may vary, to show optimum performance, but as mentioned it's all bunk to your ear.
