Unplug the internal speaker's jack from the Speaker output. Using a heavy-gauge
speaker cord, connect the output jack to the speaker input on an extension cabinet with
an 8-ohm impedance and power-handling capacity of at least 30 watts. A 16-ohm
extension cabinet can also be used, but it will reduce the amp's output by about 10
watts. You can also use a 4-ohm extension speaker.
