Massive coolant leak

[SVTopless]

On friday a massive amount of coolant leaked out of my car within 30 minutes of me parking it in my garage enough that the tank is empty. I took pictures today and their is still a little dripping out. I have found the source of the leak but I don't know what I am looking at, can someone help me figure out whats going on?

Looks like the lower radiator mounting stud. Most likely the leak is above and running down.
Check the hose and clamp above.
Do you have access to a pressure tester? Fill the system with water and pressurize.
