    So I've done some searching and I think I know the answer but I want to be certain. I have an amp that claims [email protected] or 2.67ohm (the manual shows both impedance levels at 800w.) I have three 8ohm cabinets, rated 350w each. My understanding is that I can connect all three cabinets and safely run at 2.67ohms. Since there are only two outputs on the amp; my understanding is I can run two cabinets parallel and one series from one of the cabinets. Am I correct?

    Not quite, because running from one cabinet to another is also parallel in the vast majority of cases. Which is what you actually want, so carry on. ;)

    Close. Going from one cab to another is still parallel in almost all cases.

    Ok, I had to think about that for a second but I understand what you mean. So having two 8ohm cabinets; each connected to the amp, then another 8ohm cabinet connected to one of the cabinets coming from the amp...I['m good to go at 2.67ohm?

    Yep, you just have three 8 ohm cabs in parallel. It'd be the same if you daisy chained all three cabs off one amp output too, but personally I would prefer your proposed config.

    Yes and you could daisy chain one more and still be ok.
