I bought a [TPA3116D2 amplifier like this after watching your video, it’s great, my question is does the ON/OFF switch stay in the ON positon when the power sauce is disconnected? or does it automatically reverse back to off, the reason i’m asking is because I would like to install a toggle switch on the outside of the cabinet to turn the amp on and off, my thoughts were to cut the cable after the transformer and connect to a toggle switch, any help appreciated.](https://www.kynix.com/components/TPA3116D2DADR-Audio-Amplifier-Datasheet-Schematic-Pinout.html)
I don’t think it’d automatically reset; I do think your plan works if you program it to be interrupted when the signal is cut
