Series speaker configurations Total system impedance
Two 8 ohm cabinets 16 ohms
One 8 ohm cabinet and one 4 ohm cabinet 12 ohms
Two 4 ohm cabinets 8 ohms
Three 8 ohm cabinets 24 ohms
Two 8 ohm cabinets and one 4 ohm cabinet 20 ohms
One 8 ohm cabinet and two 4 ohm cabinets 16 ohms
As you can see, problems tend to arise when using more than two cabinets.
In these cases, a combination of parallel and series wiring may be helpful.

POWER HANDLING
Your speaker system can be damaged by too much or too little amplifier
power. While the amount of amplifier power reflects the potential for
damage, how that power is used (your playing style) is the critical variable.
Too small an amplifier, when pushed to its limit too often, can generate
excessive clipping. This can generate a signal with enough extra high
frequency distortion to eventfully overheat and burn up a voice coil. Too
large an amplifier, when pushed near its limit, can push the speaker beyond
its physical limits. Your playing style determines how much headroom
(reserve amplifier power needed to handle short bursts of sound) you will
need.
Slap style playing is particularly demanding, as short bursts of low
frequency information require a great deal of power to be produced
accurately without distortion. You should choose an amplifier that delivers
adequate power for your playing style without frequent clipping and without
exceeding the cabinet’s power handling maximum during normal usage. It is
OK to have extra power for added headroom. Just be careful to use it for that
purpose.
Also, keep in mind that simply adding amplifier power will not necessarily
increase your volume significantly. The addition of more speakers will
usually have more impact on your overall volume level and improve your
overall presence and tone.
