I am planning to use (temporarily) an Ampeg 4x10 cab rated at 4 ohms in combination with two PA speakers rated at 8 ohms as a PA upgrade, running off a PA amp rated at 1000 watts @ 2 ohm; 500 w @ 4 ohm and 250@8 ohms, if possible. What I want to know is if I daisy-chain the Ampeg on to one leg of the amp output with one 8 ohm speaker, which will reduce the load to 6 (?) ohms, and leave the other channel wit the 8 ohm speaker, will this damage the amp? Conversely, if I daisy-chain from both 8 ohm speakers into each of the inputs on the cab, will it damage the cab? This will be a one-shot deal, if it works without blowing up anything! But, if it's not a good idea, no problem either! Any thoughts on this?
