You need to measure millamperes or mA. (Not Voltage)
With the SixPac turned OFF but wired to the speaker......
1) The 1/4" plug needs to be plugged into the SixPac.
2) The meter leads need to be plugged into the Common and the A or mA socket on the meter, and set the meter to the 500mA selection.
3) The meter lead probes need to be attached to the clips/leads from the 1/4" plug from the SixPac.
4) Power up the SixPac and closely monitor the meter. If the needle goes to the left, shut off the SixPac and reverse the leads. If the meter needle starts to rise to the right, monitor it and be sure it doesn't go above about 250mA.
5) Adjust the pot behind the SixPac so the meter reads about 220 - 230mA.
6) Continue to monitor the meter for about 30 minutes and make a final adjustment to 230mA.
7) Shut it all down and disconnect the 1/4" plug.
8) Repeat for the other SixPac amp.
