leaking antifreeze near fire wall

ok, i am leaking a lot of antifreeze from what appears to be a hose or line on the passenger side near the firewall, perhaps the heater core?? its really tight and hard to pinpoint a starting point. its a lot of fluid though and i haven't turned the heater on but once this year and only a short while a few days ago. it just started leaking yesterday. Any suggestions on this-anyone had this problem too?
please help if you can-thank you very much

You have a broken heater core. It's leaking out the condensation drip hose. You change it from under the dash inside. Take the passenger seat out, it makes it easier.

Appreciate the response and the tip. I figured it was and i saw that drip hose coming out of the firewall in action. I just looped the hose for now. Gna be in the market for a core soon. Any leads on one for a good price?
