OK so I have a 4x12 with 4 16 ohm speakers, rated at 16 ohms. From what I have read this means it is wired in series/parallel. I want to rewire the cab to 4 ohms, from what I've read I need the speakers all in parallel. Since the cab is front loaded I won't be able to see the 'big picture,' I'll be rewiring one speaker at a time. In the simplest terms possible, what do I need to change?

Wire the + from each speaker to the tip connector of the input jack.
Wire the - from each speaker to the sleeve of the input jack.

Or on + to the tip and one - to the sleeve, and then string from one to the next, right?

Nope. The way you drew it is series wiring. The total impedance would be 64ohms. I doubt you have an amp that will work with that!

The + on each individual speaker goes directly to the + on the jack.
The - on each individual speaker goes directly to the - on the jack.
That is parallel wiring and will give you total impedance of 4ohms.

Both methods are correct and will end up with a parallel connection. you just need all the + connections to the tip and the - to the sleeve.

A series connection is done by connecting the + on one speaker to the - on the next to make a daisy chain.

You can't do this a bit at a time as you seemed to be suggesting, just rewire the cab test with the back off at a lowish volume then put the back back.
