Question about swapping my head for an orange one

[The Thing]

Hi, I have a Marshall MG15HFX stack and I really want a tube head and so am pondering purchasing a Orange Tiny Terror. On the back of my marshall head it says 'no less than 8 ohms', but I don't know weather that means for each or both speaker outputs. The Tiny Terror has two 8 ohms outputs and one 16 ohms output I believe so I need to know if they will be compatible. Will I be able to use both cabs with the Tiny Terror or just one? or god forbid... none. I don't think there will be an issue on the power side of things as they both have 15 watts I believe. Any advice is greatly appreciated. Cheers!

i used to have the micro terror running through the Orange PPC8x2 cabs, i wouldnt see it being an issue running the cabs that come on the stacks but im sure some one here will help a little more , great amps
