Excellent and informative video. For years I've done the PA side of things and back line has always confused me. With a PA you follow the same guidance for matching the ohms but you use an amplifier that's at least 25% bigger than the speaker cab and always turn the power amp to full. This allows the cab and amp to deal with peaks in signal without clipping. The complete opposite of guitar amps. I've recently found out that guitar amps are designed to be driven hard and the cones are constructed to take it. This video filled in the last gaps. I knew that guitar gear would blow in certain circumstances, now I know when. Thank you.

5:20 'Never exceed the minimum load.' So if minimum load is 8 ohm, DO NOT plug into 16 ohm slot. Exceed means more than. 16 exceeds 8. So no more than 8ohms. But 'minimum' means at least. So 'never exceed the minimum' means use exactly 8 ohms. No more, no less. Either I am correct, or someone needs to change the wording.

It's okay to run an 8-ohm amp into a 16ohm cab, you just won't get the amp's full power, and it may sound worse, you can't run a 16-ohm amp into an 8-ohm cab, you will nuke your amp. as long as the impedance of your amp is same or lower than the cab, it should not damage anything.

It's all about limiting the electrical current from the amp. High impedance means low current, ok for the amp but won't be very loud. Lower impedance means higher current. That's why your amp can blow, the low impedance speaker isn't controlling the current to a safe level, but allowing too much- and high current means maybe enough power to kill your amp. It's more likely to blow a fuse which every amp should have. Or keep the current controlled with the correct impedance speaker or higher.

One thing to be aware of when combining amps into a single cabinet... A year ago I burned one output on a power amp by using that exact Vox amp in the other channel of a stereo cab. I thought it was really strange and started measuring with a multimeter. Apperently the Harley Benton cab I'm using has connected sleeves even in stereo (I guess they saved a few euros on a smaller switch with less poles). This combined with the Vox which apperently sends phase shifted voltage through both tip and sleeve made it so that my stereo power amp, which I've been using for years with this cab with no problems since the sleeve is 0 volts in both ends, got voltage from the Vox through the connected sleeves into its 0 and burned the amp. So from now on I'm always gonna pull out the multimeter to check whatever cab I'm connecting two amps to. If it beeps when you measure the two cables' sleeves, don't do it.

So, could I use the 16 ohm with 16ohm cabinet and at the same time use both 8 ohm output inside another 16 ohm cabinet (in the 8 ohm input right-left) ? So each output respect the rated ohm but is the amplifier able to supplied all of this or normally just able to supplied one output at the time? And if I count, its 16 ohm twice so 8 ohm would be the minimum and its supported by the amp but... Thanks!
