    You can run 2 of these speakers safely on an A1MH NANO 1 ohm version.

    We recommend a 1ohm 1 channel amp that will provide around 1000 watts RMS. You can also use a 4 channel amplifier that will provide the same power to the speakers. 

    Check out the PRV A1MH Nano 1k2 amplifier.

    I have used these on more than one occasion. Most recently I have them on a 150×4 amp and they out perform the Focals that were there before.
