Remote turn on wire

Dumb question, is the remote amp wire a constant 12v? I was under the impression that is wasn't.

Switched 12 volt.

It's a very low amperage 12v signal. The voltage just has to be high enough to be able to tell the device that it's connected to to turn on. If the remote wire dips too low or has no voltage, it turns off the device that it's connected to.

The voltage for something like amp turn on (remote wire) can come from any source you want it to. Like I say, if your remote wire isn't constant, then that's a problem, and your amp would turn off. You can measure these voltages with a volt meter or fluke or any DC voltage measuring device.

I had to tap into my cigarette lighter for my remote turn on. For some reason my Jeep had a 5 volt switched connection instead of a 12 volt from the stock stereo, causing a nasty pop when i turned off the vehicle. If the cigarette lighter stayed on constant with the key off, it wouldn’t have worked.

You can use a relay to create a soft turn on.

I could. I have the remote turn on running through a DSP using the sequencer. So my DSP turns on, then each amp turns on with a delay of 1 second behind each other. That seems to have fixed my issue.

All but 2 fuses in my car had constant power to them
There was a lot of sub humming when I was hooking the battery back up until found one that was switched
