I just picked up a speaker cabinet with 2 - 12" 8 ohm speakers. I would like to use it with my deluxe reverb. I am thinking that the extension speakers need to be wired in series and then plugged into the extension jack. This would provide 16 ohms in parallel with 8 ohms or a total of about 5 1/2 ohms on the output transformer. Seeing how it is set up for two 8 ohm speakers in parallel or a total of 4 ohms.....I'm thinking I should be ok.
Anybody have any experience with this kind of thing?

Hi,
Depends relatively on how good the drivers are. If the extension ones
are not as good it sounds very reasonable. However if they are better
then wire them in parallel and rewire the extension socket so as to
disconnect the internal speaker for extension use.
As ever the best parallel extension is usually the same as the internal driver.

Yes you have the right of it. BUT the Fender extension jack isn't really optimal. An optimal setup would have a switch to change the secondary taps of output transformer to the correct 4 ohm load.
I usually just unplug the internal speaker and plug the extension cab into the that jack. You have sort of an odd situation because you don't have that option, you can only get 4 or 16 ohms depending on if you wire them parallel or series fro the extension cab. So your original idea is probably your best option.
