When playing through multiple speaker cabinets one must remember that this will change the impedance that your amp must compensate for.
Two 8 ohm speaker cabinets.
To simplify parallel wiring pretend your speaker system has a total of 2 speakers with 16 ohms each.
A 4x12 cab is typically 16 ohms so when you connect two of them together in parallel the total load becomes 8 ohms.
Wiring configuration for 4 speakers in series parallel.
Connect positive side of speaker a to positive side of speaker c.
Four 8 ohm speakers 2 ohm load four 16 ohm speakers 4 ohm load four 32 ohm speakers 8 ohm load.
A parallel wiring of 4 16 ohm speakers has a system of 4 ohms total as well.
To push more air several speakers always of equal impedance can be wired together in a cabinet.
In parallel you simply divide the total ohm rating by the number of speakers or speaker boxes.
A parallel wiring turns those 2 8 ohm speakers into a system of 4 ohms total.
The cabinet impedance depends on how the speakers are wired and may differ from the impedance of the speakers.
Match impedances ohms all speakers in the same box should have the same impedance.
Connect negative side of speaker a to positive side of speaker b.
1 x 8 ohm speaker 8 ohm load 1x16 ohm speaker 16 ohm load two speakers remember.
Two 4 ohm speakers 8 ohm load two 8 ohm speakers 16 ohm load.
Remember we said if your amp can t handle a 2 ohm load it could go up in flames.
For instance two 8 ohm cabinets wired in parallel will have a total impedance of 4 ohms.
One 8ω cabinet plugged into another 8ω cabinet then into the amp 16ω.
Two 8ω cabinets both plugged into an amp 4ω load.
Ohms most speakers have an impedance of either 4 8 or 16 ohms ω.
That s why this is so important.
The most basic cabinet configuration is a single speaker.
Or two 8.
Running cabinets in this fashion from one power amp will give you a 2.
So if you had 2 16ω boxes then you would have a total of 8ω.
Most amplifiers on the planet can run an 8 ohm load so this is desirable.
Two 4 ohm cabinets would have an impedance of 2 ohms.
It s best to match like cabinets.
If your amp says it can put out a certain number of watts at 4 ohms you can only.
