I have a 500 watt 4x10 @ 8 ohms cab and a 200 watt 18+2x10 @ 4 ohms cab. Can I run this combo through a Peavey Nitrobass 450? It puts out 450 watts @ 2 ohms and i've got 2.667 ohms, if my math is right. Is there a possibility of damaging the 200 watt cab? The DDT protection light doesn't come on...
