In Reply to: Use of multi-meter for measure impedance of lines Question.. posted by Elvis on March 19, 2007 at 09:37:25:

Impedence is dificult to measure w/ a meter. If you want to accomplish (almost) the same thing, measure the DCR of an individual driver and use that spec to determine the desired value of whatever your series/parallel total should be. If the measured value varies much from the predicted value then someting is wrong in your wiring.

If you are just trying to get lucky and experiment w/ with different wiring variations w/o taking the time to calculate (or learning how to calculate) a practical wiring scheme then just make sure the DCR of you combo is above that of a sigle driver. This will not necessarily provide good performance but it will keep you from killing your equipment. Sorry if this portion of my answer seems off base but I have no idea how much experience you have w/ this kind of thing and I am trying to keep you out of trouble.
