    I am really unfamiliar with mixing series and parallel wiring, but i am sure someone will know how to do, what i am trying to do.

    I have three paris of 6ohm speakers that i want to run from a dual channel Power amp (three off of each channel)

    I do not want to go below 4 ohms, and ideally like to stay at 6ohms.
    Can someone draw me a little diagram showing me how it can be done?

    Thanks

    Andy

    Speaking from just an electronics point of view

    all three in series = 18 ohm
    all three in parallel = 2 ohm
    two in series and one in parallel = 4 ohm (but uneven loading)
    two in parallel and one in series = 9 ohm (but uneven loading)

    Can't think of any other combinations.

    Cheers,

    Nigel

    Hmm,

    Buying a fourth pair of speakers evens out the load then?

    With four you could do

    (2 in series) in parallel with (2 in series) = 6 ohm

    So the load will be even, but remember that each speaker will get 1/4 of the delivered power.

    So if your amp supplies 50W ...

    For a single speaker ... it will deliver 50W
    For 4 speakers ... each will deliver 12.5W

    Cheers,

    Nigel

    Cheers,

    I have done a quick sketch as to how i think i need to wire it for 6 Ohms. Does this look right?

    Wiring

    Thanks

    Yep, that's what I meant - bear in mind this is from a purely electronics point of view - I couldn't comment on what it would sound like.

    Cheers,
