Bridged Mono

Hi everyone, have a super basic question...

If you take a stereo amp which supports bridged mono, the watts usually double, i.e. 100 watts @ 8 ohms -> 200 watts @ 8 ohms. I have noticed even if the amp is rated at 150 watts @ 4 ohms, the specs do not show 300 watts @ 4 ohms bridged. Is 4 ohms not rated/recommend in bridged mode?

Thanks!

UPDATE: Sorry should have searched more thoroughly this was answered here: https://forum.audiogon.com/discussions/will-the-4-ohm-double-if-i-bridge-my-mcintosh

If all your after far bigger watts at the expense of lowering quality, then bridging is the way to go, but all else will take a hit.

Stability
Damping factor
Distortion
Output impedance
Ability to drive low impedances
Maybe can also throw higher noise in there too
There's probably others as well.

Cheers George
