#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. |

| if it is 12V hi/lo and less than 200mA | 01/01/70 00:00 | |
| Amp needs 12v for switching | 01/01/70 00:00 | |
