So I have some understanding of the usual ohms setting for speakers questions. I read a post here recently about two 2x12's into one output from the JTM45 but my 'query' is a little different. I have a JTM45 and want to run it into two JVMC212 2X12 cabs. Each cab has two 8ohm speakers in series. So - if I run one cab I set the JTM output to 16ohms to match one cab? And if I run 2 cabs I set the JTM to 8ohms on the basis that the two outputs from the JTM put the cabs in parallel? And finally - what if I want to add a hotplate into the 2x12 setup for gigs? Do I need 2 hotplates, one for each speaker output? Or can I do the Y cable thing mentioned in the other post - then into one hotplate, then back out to the 2 cabs? Sorry some of this has been said before but I cant find a thread that specifically deals with the hotplate with 2 cabs setting on the amp.
