MIG100H Speaker Wiring

[Walt-Dogg]

My MIG100H has 3 speaker outputs, one 16 ohm, one 8 ohm, one 4 ohm. How do I get this to plug into a full stack of two 16 ohm or two 8 ohm cabs?

Two 16 ohm cabs = 8 ohms, run it out of the 8 ohm jack.

Two 8 ohm cabs = 4 ohms, 4 ohm jack.

Cabs get paralleled, parallel down, series up. Parallel 2x16 = 8 ohms, Series 2x16 = 32

So, can you parallel a Marshall 1960 4x12, the kind with the ohm selector switch on the back?

Just run the Marshall mono, I think it's 8 ohms. You could parallel it with another 8 ohm cab to the 4 ohm tap.

If you mean can you run the cab stereo and parallel the two sides...
Well you could, but that would be a waste of cable and time; just run it mono off the 8 ohm tap.

Not if it's the 16/4 ohm switchable Marshall. You can't daisy chain those.

On further research, I see the cab is 16 or 4 in mono, so obviously paralleling with another 8 ohm cab wouldn't work, so I'll change it;

Just run the Marshall mono, I think it's 8 ohms 16 or 4 ohms. You could parallel it with another 8 ohm 16 ohm cab to the 4 ohm 8 ohm tap.

If you mean can you run the cab stereo and parallel the two sides...
Well you could, but that would be a waste of cable and time; just run it mono off the 8 ohm 4 ohm or 16 ohm tap.

Would that work?

I should go ahead and say NEVER use two of those jacks together. Not meant for that.

The 16/4 Marshalls aren't chainable. You COULD, in theory add a third jack back there paralleled from the 16 ohm (or 4 ohm)jack, so you could run it to a second 16 ohm (or 4 ohm) cab for a total load of 8 (or 2 which that amp won't do.)

[Walt-Dogg]

Oh well. I'm gonna invest in a pair of Orange or Avatar 4x12s soon that have parallel jacks so I can rig the MIG to two 4x12s no problem at 8 ohms and have a second 16 ohm cab to run with my Model T and 16 ohm Marshall 4x12 also at 8 ohms.

We have a similar setup, buddy!
