Re: How many volts does and amp remote wire carry?
if you are the least worried about it, then put in a relay, then who cares about the voltage.
or you can wire in the led which takes almost no power, and not worry about it, because it is not enough voltage to worry about.
just so you know, some amplifiers like, um cheap ones (pioneer, power acoustik, etc etc) have been known to draw up to 10 amps through the remote lead. so always using a relay (4.99 at most autopart stores) kind of makes sense if you think about it.
their is doing an install right, then there is doing an install right and proper.
