Engine aggressively stalls when ac is turned on

[andrewbse]

So I bought this 2000 boxster with 65,000 miles on it in november last year. Two weeks after my purchase the clutch goes out so I figured it was a good time to do the ims on it. Five months later due to some unexpected life events she's all buttoned up and running better than when I picked her up. Now 2 days after that I started to get a weird idle fluctuating from 600-1000 rpms sometimes very close to stalling. After some playing around I figured out that it only happens when the a/c is on and the compressor is running. Today I started the car though and the ac came on and I immediately felt the car aggressively stall. I'm thinking it has to be a seized compressor or something of that nature any ideas would would be very helpful thank you.

Unplugged the ac compressor relay and its running like a champ now going to replace the compressor this week and some other a/c components.
