2 ohm wiring question

Discussion in 'Amps and Cabs [BG]' started by insomniac2295, Jan 13, 2009.

  1. right now, im in the midst of wiring my 8 ohm avatar 410 neo for 2 ohms so i can put more watts from my peavey max 700 into it. heres how i have it wired:
    speakers 1 and 2 are connected with the positive wires coming from the inputs and outputs from the cab. speakers 3 and 4 are connected with the negative wires coming from the inputs and ouputs from the cab. Then, I have negative wires coming from speakers 3 and 4 going to speakers 1 and 2. And last, I have positive wires coming from speakers 1 and 2 going to speakers 3 and 4.

    Did I loose you?

    The way that I would say it is that I wired the four 8 ohm speakers in parallel for a net impedance of 2 ohms.
  3. yeah, a little after i wired it, i realized that it wasnt right. now i have them wired up for a total impedance of 2 ohms but 2 of the speakers dont have any sound coming out of them. does anyone have a diagram of how to wire this?

    Parallel wiring is just "daisy chaining" positive to positive and negative to negative until you have all the speakers connected. Four 8 ohm speakers wired this way will put the cabinet at two ohms.

  5. would it work if i connected the wires for the input at the beginning of the chain and the wires for the output at the end of the chain?

    For parallel wiring, there is no "end" of the chain. All positives are the same, all negatives are the same. You could run the input jack off the 2nd or 3rd speaker, no difference.

    Right. It doesn't matter which speaker you start with, as long as they are all connected pos to pos and neg to neg.

    There is no output, only signal and ground. BTW, you're total output capability probably won't change by a noticeable amount. It will be louder at a given setting of the amp master volume, but an eighht of a turn higher would make up for that. You might get an additional 2dB broadband output, not an earthshaking amount by any means. Adding a second identical cab, OTOH, would have given you another 6dB.

    I think by "input" and "output" he means the parallel jacks on the cabinet that allow connection of multiple cabs without splitter boxes or Y-cables.

    The answer is that the "input" and "output" on the cab are completely interchangable in this context. They are identical jacks wired in parallel, so take your pick.

    If you have two inputs on one cab,
    you can run one to the amp, and another to a second cab.

    It's the only way I'd do a full stack with guitar.
  14. youre right. thats what i was trying to say. see, not everything bill says is right!

    It is quite rare for me to find a mistake in one of Bill's postings.
