*Single functional PD60 driver will read approximately 9.5 - 10ish 10 ohms directly from the terminals on the driver, not including any wire*Four PD60 drivers will read approximately 2.5ish 5 ohms when wired together in parallel with a short length of wire*Two PD60 drivers together will read 5ish approx. 5 ohms when wired together in parallel with a short length of wire*Four PD60 drivers wired into a speaker line roughly 250ft. in length will read approx. 3.8ish 8 ohms*Four PD60 drivers wired into a speaker line that is 25ft. will read approx. 2.7ish 7 ohms

# At the amplifier location, disconnect both wires of the speaker cable from the amplifier. Take preliminary measurement with speakers still connected on the two wires of the line at the amplifier end. Compare to the readings above (Testing Speakers) and write it down.
# Leave the two wires at the amplifier end disconnected, not touching each other, or any other conductive material.
# Go to the speaker location, open the junction box, disconnect the cable from the amplifier from the speakers and take a measurement. There should be no resistance reading (no change on the Ohm Meter's display). Any numerical reading on the meter will indicate a short on the speaker cable.
# At the speaker location, short the two wires together on the cable that runs down to the amplifier. Then at the amplifier end of the cable put the Ohm Meter test leads on the two wires of the cable. A non-numeric reading will indicate an open (possibly cut) cable. For 14 AWG SJTO cable, you should see about 0.006 Ohms per foot of cable (don't forget to subtract the resistance of your meter's leads).
