Using a heavy-gauge speaker cord, connect the output jack labeled Speaker 2 to the
speaker input on an extension cabinet with a 4- or 8-ohm impedance and power-
handling capacity of at least 100 watts. A 16-ohm extension cabinet can also be used in
conjunction with the internal speakers, but it will reduce the amp's output. Don't use a 2-
ohm extension speaker.
Note:
Make sure that the Speaker 1 output is connected to the
Hundred Duo Twelve's internal speaker.

This setup is for employing the Hundred Duo Twelve as a head; its speaker is
nonfunctional in this configuration. Unplug the internal speaker from the Speaker 1
output jack. Using heavy-gauge speaker cords, connect the output jacks labeled
Speaker 1 and Speaker 2 to the speaker inputs on extension cabinets with an 8-ohm
impedance and power-handling capacity of 100 watts. You can also hook up two 16-
ohm cabinets or two 4-ohm cabinets, but never use two 2-ohm cabinets, because the
overall impedance load will be too low for the amplifier and could result in damage.
