   Good post Kim :thumb-up:

     This should help eliminate the confusion when people go to install custom speakers and re-wire their amps/cabs, just as long as they remember to pay attention to the Nominal Impedance requirements on the amplifier!

GREAT idea, Kim  :thumb-up:

I wish this had been here when I got my 4x12 cabinet & rewired it for stereo. Coulda saved me some searching - which it will do for others now, thanks to you  :bow:

Of note though, where it says "ring" it should say sleeve so not to be confused with Tip, Ring, Sleeve (TRS) stereo jacks. Mono jacks, as used in these diagrams, are Tip Sleeve (TS) jacks not Tip Ring (TR).

A useful wiring is how I did one of my Split stacks so if you plug into one jack the cab is mono with speakers in parallel, if you plug into both jacks it splits the speakers to be separate (stereo).  The speakers in it are 16ohm so it's either 8 ohm mono or 16 ohm L, 16 ohm R (which is how I typically use it).

Thanks to GuitarBuilder for providing this extra attached info.   :wave:  A lot more in-depth and comprehensive, should anyone require that. 

Check out the attached article - it has every conceivable 4x12 wiring combination.

What would the wiring look like, if I wanted to use a 2x12 either in Stereo or in Mono(Series)?

So 8 Ohms each side or 16 Ohms Mono?

Can I use 2 switchable Jacks or do I have to use 3 Jacks?

Edit, you wanted series not parallel  :facepalm: , here's how to do it easily parallel..
Hey Griphook, this is how I've wired one of my Split stacks (2 x 16 ohm celestion 70s) so in stereo (both jacks) 16 ohms per channel.  Mono, one jack 8 ohm (speakers in parallel).

So you need 2 jack sockets, one normal and one switching (connects the tip (+ve) to the sw lug with no jack inserted).

+  16ohm   -       + 16 ohm  -
 |             |       |             |
 |             |       |             |
 |             |       +            |
 +_______ |__ sw lug         |
               |                     |
               - _____________-

So wire SP1 to normal jack (+ & -), wire SP2 to switch jack (+ & -), wire normal jack +ve to switch jack switch lug.  If the jacks are not earthed together through a metal plate, then also wire the normal and switch jack - ves' together (red line).

So when you plug into normal jack only, both speakers mono in parallel.  When you plug into both jacks, the join between normal jack + and switch jack + is broken (goes nowhere) so is now stereo.
