Speaker cab wiring, dual input amp head

[redkurn]

So I've replaced the speakers in my cab and am thinking of adding a second input, any considerations I should take with plugging two amps into the cab, but only using one at a time?

Also might add another two inputs to drive two sets of speakers separately.

Tube or solid state amps. Either way, I'd use a DPDT switch so you can switch between amps. If either is a tube amp you will have to use a power resistor to load the output of the tube amp when it isn't connected to the speakers. It's also a good idea to load a solid state amp if you're using one of those.
Good luck

BTW, and this is important... Amps do not like sharing the same load at the same time, you'll destroy your amps.

So probably not a good idea for me to do this, since I don't have a load box.

I have a A/B box I built, two input, one output which can be used in the opposite order.
It's wired to a DPDT toggle for switching between A and B, thick speaker wire.
