    I went to the FAQ but all the math made my head hurt...

    Very simply, I have a 400-watt head (into 4 ohms) with two speaker outputs, and two 8-ohm cabs (Hartke 410s). Is it better to feed each cabinet from one of the outputs, or daisy chain both cabs from one output?

    Thanks in advance.

    I would daisy chain them. That way the cabs will be running at 4 ohms. I have the same setup and I made the mistake of connecting each cab into the two speaker outputs at a gig. My amp shut off after the first song.
     
  3. I don't know if one way over the other is better, but you end up with the same result, maximum 400w into 4ohms.

    Personally, I use one output per cab.

    If your head has two speaker outputs, it is best to run the cabinets from those, not daisy-chaining them together. This ensures maximum power/signal transfer from the head, and also ensures that you're getting true 4 ohm power from it. 2 8-ohm cabs equal 4 ohms total output, so you're getting the most out of the head for sure.
     
  5. I gotta ask: is this a mono amp with a pair of parallel outputs, or a stereo amp?

    If 1/4" phone plugs, and or very thin wire, definitely go two cables from the amp.

    With Speakons, and half decent wire, there will be no difference.

    For a PA setup, with a 30 foot run to a speaker stack, I'd run heavy gauge wire, and daisy chain the cabs, just to keep the stage neat.

    Amp is an SWR WorkingPro 400, mono with a pair of speaker outlets.

    Yeah, I'd say definitely run one speaker cable to each cab from the head. Remember, in the case of speakers/cabs, the shorter the cable the better, and at least you know the signal is coming directly in from the head to both cabs. I feel it works better this way for your basic amp/cab setups. YMMV.
