Just picked up a 2 x 12 Vox extension cab with 2 Celestion Blues. It's wired in Series (one wire to one speaker's + and one wire to the other speaker's - and one wire between the 2 speakers + to -) The Blues are each stamped in black with 16 ohms. So this means the cab is wired at 32 ohms. Am I correct on this? Very odd that is was wired this way. 1st off, are Blues stamped with 8 or 16 to designate the ohm rating of the speaker. 2nd: I probably should wire this to an 8 ohm cab. Can I just run a jumper wire from one speaker's + to the other speakers + and do the same with the - terminals. This will let me use the original wiring and just move the original jumpered wire and add the one more connection. Thanks.
