Can I wire up a 1X12 cab so that I have two 8ohm heads running into two separate jacks that are connected to the same speaker? I want to use an ABY box between my guitar and the heads to select, but I don't want to use another ABY between the heads and the cab. Simpler just to plug each cab into separate inputs. Both heads would be powered up and plugged into the jacks, but only one would have a guitar signal running through it at any given time. Would this work, or would it blow my speaker? Or have other horrible consequences?
