    My Trace Elliot V-type 600 head says on the back, MIN 4 OHMS. Does this mean I shouldn't run 2 ohms through it or 8 ohms?
  2. It means it requires a minimum of 4 ohms. You can't use a 2 ohm load, but you should be able to use 4 or above.

    Another way of looking at it is this:

    1 8 ohm cab = good
    2 8 ohm cabs = good
    1 4 ohm cab = good

    3 8 ohm cabs = BAD
    1 2 ohm cab (do they make those?) BAD :confused:
    2 4 ohm cabs = DISASTER ;)

    As long as the load you present to the amp is 4 ohms or higher then you'll be OK.

    So, 1 x 8 ohm cab is OK, but you won't use the maximum power from the amp. 2 x 8 ohm cabs present a 4 ohm load (from Ohms Law and parallel circuit rules! PM me if you want more info!), as does 1 x 4 ohm cabinet.

    What you can't use is 2 x 4 ohm cabinets, these give a 2 ohm load. Also you cannot use 1 x 8 ohm cabinet with 1 x 4 ohm cabinet as this gives a load of 2.67ohms.

    This response is pretty much what the other guys are saying just in a different way!
