    Hey all. Just been having a look through the FAQ's trying to find an answer to my stoopid question, but couldn't find anything specific, so thought I'd give it go in here.

    Basically, I was wondering if anyone could enlighten me as to how the watts from an amp are distributed to cabs in a rig set-up? Do the watts get distributed evenly to each cab (i.e. split down the middle) or does it depend on how many cones you're running on the whole cab set-up?

    The reason I ask is because I've got a 115 rated for 200w and 410 rated 400w. My head puts out 480w @ 4 ohms and 320w @ 8ohms. Just wanting to know for the sake of knowing really, and so I can better assess any future cabinet additions to ensure I don't do anything that would risk my gears.

    Anyway; stoopid, annoying question probably, but thanks in advance. :meh:

    need more info. what's teh impedance of each cabinet? (ohms)

    the rating of the power handling (watts ) of the cabs isn't relevant.

    If they are both 8 ohm cabinets then they will both see 240 watts each

    Both 8 ohms (400w/8ohms 410 & 200w/8 ohm 115)

    So would it split 240 into each? That would be too much of an issue for a cab with a 200w rating...?

    if htey are both 8 ohms, it'll "split" the watts evenly between the cabs.


    should be fine. uness you have it cranked "to 11" and are giving the low eq a workout.
