    If I use 3 8 ohm cabs wired in parallel what is the total ohm load on the amplifier?

    2.67 ohms, as always.

    For future reference:

    1 / (1 / R1 + 1 / R2 + 1 / R3) = Total Impedance

    Give a man a fish, etc...

    I forgot something (usually I'm the first to point out : D ):

    There's no such thing as "ohmage", it's called impedance.

    But ohmage sounds so much cooler than impedance :D



    Anyways, what impedamce rating should an amplifier be if you were to connect a 2.67 ohm load? Do you go higher to 4 ohms, or lower to 2 ohms?

    Yes, that's the way Pauly Shore would say it.

    Your amp should be rated for two ohms if you're going to run it at 2.67.

    Thanks Munji :)

    Is the rule different for SS vs. Tube?

    Probably, but I'm going to defer to those giants of tubeage, Bob Lee and Psycho Bass Guy. My comments pertain to solid state only. Tube amps have excess suckage.

    Just for the record, I know there is no such word as ohmage, but I figured you would know what I meant, which you did. I'm sorry I didn't know everyone here was such a stickler for eletrical engineeringagely correct terms. I mean, we are bass players after all.

    well if we're being "electrically correct", the correct term is actually "Nominal Impedance". So take your foot out of your mouth, gt on your knees and apologise profusely........ :)

    Well you're like the singer I worked with last night who kept asking the sound guy to turn up her feedback....
