A matter of identifying the taps (the wires from the transformer) and then putting them onto a switch, like a rotary switch. It's not difficult really, but you need to make sure which tap is 4, 8 and 16 and common. Then just wire that to the speaker output jacks. Peavey made the impedance switching fairly automatic, which is good for most users.
I might be able to come up with some info on this amp, like layouts and color codes. Once the impedance switching is made manual, a half power mod would be easy. If you are interested.

Liberty has always come from the subjects of it.
The history of liberty is a history of resistance.
The history of liberty is a history of the limitation of governmental power, not the increase of it.
