I have a 70s Fender Twin Head, the output is 4 ohm and I want to run it into my Marshall 1960AX with greenback speakers, which has a 16ohm input.

Is this a safe combo, or do I need to reword the cabinet in some way?

Any help would be greatly appreciated.

If you are going to use this cab permanently... attaching the TR amp --- best to rewire the speakers in parallel = 4 ohm total impedance.

Ya, if the Marshall cabinet is wired in series and they are all 4ohm drivers, then wiring in series-parallel will result in a 4ohm load.

Pair the speakers in series.
Parallel the two pair.

Or pick up a Weber Z-Matcher. You can run just about any amp/ speaker combination with it.
