So I bought a Mesa oversized cab the other day that someone had swapped all crazy speakers into. There are only 3 jacks on the plate - 4 - 4 stereo and 1 - 8ohm.
Even though they were all 8ohms, the 8 read 44 ohms. the 2 - 4's read 8 each.
I pulled out the speakers and loaded in some 16 ohm - G12-65's. I rewired the cab in series parallel, according to the mesa site, but wasn't sure about the wires running to the jacks.
I ended up with the stereo jacks reading 16ohm each and the mono reading 2ohms.
the 4's are the plastic jacks and the mono is a stereo jack with plain wires connecting them together.
The problem is, Mesa doesn't provide the wiring diagram for the backplate correctly, so I don't know what to connect the wires going to the jacks to for sure, and I also don't know whether or not my Stereo jack for my mono signal is working correctly or not or if I wired something incorrectly, since it is only reading at 2ohms and I know they are prone to failure.
Can someone help me wire this up correctly so I end up with 8x8 stereo and 16ohm mono? (since my speakers are 16, not 8's).
and if someone can take a picture or provide a picture of the inside of their jackplate and where those wires are actually connecting to the speakers, that might help as well.
Thanks!
