Is it ok to have 12 volts on your remote wire to your amp?

Yes, it's generally acceptable to have 12 volts on the remote wire to your amplifier. This wire is designed to send a signal from your head unit to the amp, telling it to turn on when the car is powered. A voltage reading around 12 volts indicates that the remote wire is functioning correctly. However, ensure that the voltage remains stable and does not exceed 12 volts significantly, as this could indicate an issue.
