#190376 - Car amp remote signal
Hello.

I want to create a device to switch car amp sending the remote signal to it using a microcontroller.
I have searched lots, the only information I found it is positive activated with 12v.

How can I sucessfully do this?
Firstly I thought in using a small mosfet, but as it is positive activated it would need to be a P channel but I cant buy any small P channel mosfet here.

Thank you.
