#190389 - Amp needs 12v for switching Responding to: ???'s previous message |
Hello Erik.
I want to make a device to switch car amps, not for an exact model. I believe they are pull-down because they need 12v on remote input to switch on. When remote is open they switch off... I believe 0v it should switch off also. Would be something like this? Can I use this? 
Thank you. |
