Does anyone know if the stock amp is 2 ohm stable?

Thanks!

 

It is definitely not!!!

 

You asked that already and I answered you here https://acurazine.com/forums/audio-video-electronics-navigation-22/stock-amp-2-ohm-stable-764187/

I’ll take a shot that you want to run the infinity 2 ohm speakers with the hope that it will double your power output and sound level. It won’t, contrary to what the marketers want you to believe, going from four ohm speakers to two ohms won’t magically double your power, sure, if the amp was a pure source with a perfect 0 ohm impedance it will but not in the real world. In the case of the TSX amp it is optimized to run 4 ohm, showing it lower impedance will cause the chips to run hotter and eventually rollback or shutdown.

When selecting speakers always go for sound quality, if you want it louder then invest in a good amp to run your better speakers.

By the way, the 2nd gen TSX with ELS will handle 2 ohm speakers.
