    ok, im in a bind. Have a head that wants a 16ohm speaker load and one that needs 4ohm (marshall/fender). I have only one speaker cab and it is running at 4ohms for my bandmaster. I think i can do both in the same cabinent but i seek clarification and guidance from those that have come before me. I found a good diagram but i lack the understanding of "mono" and "Stereo" when applied to guitar amps. This diagram seems to have more features than i need.

    can't i just wire the cab with two input jacks to have access to both impedence choices? Do i need a switch or something?

    thanks for the help

    Am I correct in assuming this would be two eight ohm speakers being swithced from series to parallel wiring?


    You could also do this with FOUR 4 ohm speakers. Run them all in series for 16 ohms or run two parallel sets in series for 4 ohms total.

    this is the wiring I would use but without the mono/stereo switch.

    Hard wired to the mono setting all the time, one jack would be 4 ohms and the other 16.

    Just use standard mono 1/4" jacks instead of stereo jacks

    ok, i will study it!

    sooo ...the switch is only for the mono/stereo feature i dont need. Would this wiring be any different than say normal wiring for two 8ohm in series or parrallel alone?

    i guess i will find out when i get a chance to do it.

    thank you guitarcapo
