    Someone will come along with a better answer. In the meantime, @sphinxvc don't do that!

    If a stereo amplifier is bridgeable to mono, it would be in the amplifier's instructions. Otherwise, it would be safe to assume that the amp does not have the capability.

    That is my understanding, anyway.

    As Dino mentioned, generally not the best idea unless the amp says it's ok, but here's how you hack it:
    - only doable if your amp uses common ground on the negative speaker terminals
    - requires a balanced source with symmetrical output, and preferably has that symmetry across ground (do shenanigans with a DI box and resistor splice if you're feeling like sorta vaguely protecting yourself here)
    - split the hot pin to one side and the cold to the other (I'm assuming rca inputs, reference the signals each to ground)
    - so basically you're feeding each amp channel the reflected signal of the other and smashing the outputs together
    - repeat the two previous steps for the other channel and another amp

    And as @schiit or any other (reasonably) sane manufacturer would tell you at this point, "This will definitely void your warranty"

    I have never bridged a power amplifier that I did not think the sound quality was adversely affected as a result. I would be more inclined to ask why you would do it than how.

    If you're not sure - only do it if there is: (1) a "bridged mono" switch on the back, and (2) official instructions.
    An amplifier that has been designed to be bridgeable will do the required phase split and inversion itself.
    Bridging may have additional limitations on driving low impedance (less than 8 ohms) loudspeakers.
    Anything else requires technical knowledge of bridging and the amplifier itself, and is experimentation.
    If you get it wrong there is a real risk of catastrophic damage occurring.

    LOL. Don't worry guys, I'm not about to blow up my F3. :) I was just wondering how people were running First Watt F3s as monoblocks, since it doesn't explicitly say they're monoable.

    I guess maybe those are DIY versions.

    Found this online, sent an email to a dealer to confirm.
