Default AC likes to vibrate??

So she's fine when I'm driving above around 25mph, or when i'm accelerating from any speed. but when i drop down below that, or heaven forbid i stop at a light, the AC will vibrate the car like mad. so every time i aproach a stop light, i have to turn the air off until i go again. An upgraded AC was put in right before i bought the car, and started getting funky shortly after.

Upgraded how? If something other than the Harrison R4 compressor (though from the photo, it looks like the stock unit), check pulley alignment, belt tensioner.
