wait.... I'm confused

You really can't take to much truth in advertising. how would you know without testing that the amp that it puts out 120 watts. I noticed they didn't say at what Ohm's. It may really only put out 60. Bigger numbers look more impressive.

It may put out 120 at 8 Ohm's , 60 at 16 Ohm's. Now if the speakers are rate at 100 watts at 16 Ohm's for each cabinet. Then you set the amp at 16 Ohm's and connect each box to a seperate speaker out. You'll have 60 watts at 16 Ohm's into a cabinet rated 100 watts at 16 Ohm's.. Advertisers will add the two outs and come up with 120 watts.

In the same token if the amp is set to 8 Ohm's and you plug one cabinet in the head and one cabinet into the other cabinet you'll have 120 watts at 8 Ohm's. Divided by both speakers it's still 60 watts in each cabinet. Anyway connecting 2 4x12 cabinets it will move some air and be loud.

I could be way off but it sounds right.

First of all, that 120w is devided up between 2 cabs, so each cab is only geting 60w. Plus, there are 8 indivual speakers total, so therefore, even at 120W, each speaker would only be getting 15w, which i'm sure that they could handle.

Yep, xg5a has it.

Speakers of the same impedence split the watts evenly.

So when you see a 100 watt amp sitting on top of a 4 X 12 cabinet, each speaker is only getting 25 watts each (if they are all the same impedence)

Now, if the speakers are different ohms or impedence it might be different, but I don't know how to figure that out.

Now this is purely a guess, but if you had a cabinet with one 8 ohm speaker and the other was 16 ohms with a 100 head @ 4 ohms, then the 8 ohm speaker would (at least it seems to reason) draw twice the power of the 16 ohm speaker. So the 8 ohm would get 66.67 watts and the 16 ohm speaker 33.33 watts. But even that is not perfectly true because that would be a 6 ohm load (I believe. I can't remember the formula). :D

oh i see. Just looked kinda funny to me. That makes sense though thanks.
