Members gherb Posted July 13, 2009 Members Share Posted July 13, 2009 Hi all, I'm a newbie to head / cab setups, as I've only played combos for the 13 years of my guitar playing life.... I was wondering about altering my setup for amplification... Can I safely run a 4 ohm head into a 16 ohm cabinet? I'm looking to put my twin reverb head into an orange 4x12 cabinet...I want more crunch and volume out of my twin...I also want the flexibility of switching out different heads when I need them. Please let me know! Thanks! Link to comment Share on other sites More sharing options...
Members GCDEF Posted July 13, 2009 Members Share Posted July 13, 2009 On any give day there are at least three threads asking the same question. No you can't. A whole bunch of wrong answers applicable only to solid state amps are sure to follow. More speakers does not necessarily mean more volume. A whole bunch of wrong answers talking about "moving more are" are sure to follow as well. Link to comment Share on other sites More sharing options...

No. Rewire the 4x12 to 4 ohms. Link to comment Share on other sites More sharing options...
Members gherb Posted July 14, 2009 Author Members Share Posted July 14, 2009 how would I rewire a cabinet? complex soldering? I know that the cabinet wouldn't be much louder. I'm just looking to find a setup that is conducive to me switching out different heads w/ me having to have 5 different combos taking up a {censored}load of space Link to comment Share on other sites More sharing options...
Members Inca Roads Posted July 14, 2009 Members Share Posted July 14, 2009 Always match the Ohms of your head to your cab. The way you're suggesting, will ruin the Amp. Ex. 4 ohm head/ 4 ohm cab... 8 ohm head/ 8 ohm cab Most heads have a Ohm dial on the back allowing you to set it at 4, 8, & 16. If you have 2 Cabs always divide the Cab ohms by Two then set your head to match. Ex. 2- 16 ohm cabs divide by 2 = 8 Set your head for 8 ohms. Never exceed the Ohms of your head, A higher Ohm Cab will Damage your head permanently. Hope that helps Link to comment Share on other sites More sharing options...
Members JMR Posted July 14, 2009 Members Share Posted July 14, 2009 so can I run an 8 ohm through a 4 ohm cab? Link to comment Share on other sites More sharing options...

Members Riff1970 Posted July 14, 2009 Members Share Posted July 14, 2009 Oh crap. I thought you could run a higher load but not a lower one. I never did, but I thought you could.I'm glad I read this thread. Link to comment Share on other sites More sharing options...
Members Uncle_Milton Posted July 14, 2009 Members Share Posted July 14, 2009 just match them, don't mess around with it. Link to comment Share on other sites More sharing options...
Members gherb Posted July 14, 2009 Author Members Share Posted July 14, 2009 is there a way to alter the ohm output of a particular amp. My twin reverb used to be a combo amp...I recased it into a head unit for more flexibility. It is a 4 ohm output without selector switch, and I want to buy a cabinet that I can use with a great deal of other heads.... One that I can switch quite a few heads into...Like: An orange head, vox, and my fender....maybe a sunn beta bass. Link to comment Share on other sites More sharing options...

Some Marshall cabinets can run all 4 speakers at either 4 or 16 ohms, or two of the speakers at 8 ohms. That's about as flexible as you can get in a cabinet. Alternatively, there's this.
