How many runs of 1/0?

I would assume you have at lest two big batteries if you plan on running it at 1ohms. If you're referring to just running a front single battery that won't be enough battery for 7kd at 1ohms. If you do have a second battery in rear then from the battery to the 7kd if the run is less then 3 feet you'll be fine. If longer you can double it up and it'll help.

What's your electrical? That may help answer your question.

270 amp alt, 3 power master d3100's on the trunk, 1 power master d2700 under the hood and 2 runs of 1/0 will do 3 if necessary.

1/0 is rated at 300 amps. With your two you are at 600 total, but with 3 D3100's in the back, I doubt it draws the 780 amps all from the front. You should be fine with two runs.
