Just remember that a "2 ohm stable amp" means that it is 2 ohm stable in stereo - if you bridge it, it is only
4 ohm stable.
...if you have a 1 ohm stable amp, it'll be stable to 2 ohms when bridged. Etc.
The reason is that the components on your amp can only withstand so much power passing through them - power creates heat. Too much power, and electronics in the amp will melt just like a fuse getting too much current through it.
When you bridge an amp, the voltage of both channels combine, doubling it, requiring less current to make more power. And since the current draw is a function of the load you connect (impedence - see "ohms law"), you can't run a 2 ohm stereo stable amp at 2 ohms bridged.
