You can definitely use speaker wire for 12v power. The only factor to consider is the wire gauge. Various gauges will allow for higher or lower amperage, which, when multiplied with volts (in our case 12v), will give you the electrical load (watts) that the electrical device or appliance should be.
Can you use 14 gauge speaker wire for power?
Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm speakers, 16 gauge wire will usually do just fine. It's cost-effective and easy to work with.
Can you use speaker wire as power?
You can use speaker wire for electrical uses, but you must pay attention. In the earliest days of home audio, speakers were often connected with simple electrical wires, or "lamp cord." This substitution works in the opposite direction as well, and you can use speaker wire as electrical wire in many cases.Apr 10, 2020
How do wired speakers get power?
"Wireless" speakers always have an AC power cable (wire) that needs to be plugged into the wall. Normal "wired" speakers get the music over the wire, and the power that travels over the same wire from the amplifiers in your AV receiver.Aug 14, 2011
