There are a few products on the market that can send audio over powerline(120v or 220v) but I couldn't find anything that can transmit audio over 12V DC line. I have an unique situation where I need that and I have one pair of 18 gauge cable used for 12v - and 12v + from a battery.
Distance length is 20ft. Quality desired - don't care that much since anyway it will be used for a bullhorn. Anybody has any ideas of a circuit that could allow me to accomplish something like that?
As a side note, yes, I truly need this and I can't add another pair, since most people would recommend that. The existing 1 pair cable is a special rubberized line that is going through a complex pulley system attached on a spring retractable real and I can't replace that.
Thank you guys
