I have two 8ohm cabinets daisy chained together. What speaker output can I plug this into? One of my amps has two 8ohm and one 16ohm and the other has an 4, 8, and 16ohm outputs. I think it is 4ohm. Can I plug a lesser ohm into a higher ohm output without hurting the amp. Amps Egnater Rebel 20, Blackstar HT-5
Dude, you don't need to bump threads.
And by daisy chained, do you mean one cab connects to the other cab which connects to the head?

With tube amps impedance has to be spot on or you'll blow the output transformer.

I've never used a cab that links to another cab, but I assume they can be connected to the speakers differently. Do the cabs say anything about parallel/series? I'm assuming it'd be in Parallel which would make it a 4ohm total load.
