The Current in Speaker Wires
People are taught to be cautious around electrical wires – all kinds of wires. Commonly in American homes, most of the wiring carries either 110 volts or 220 volts, but what about speaker wires? Are they dangerous? Do I need an electrician to hook them up?
That depends on how you want to install the wires, and the power output of your amplifier or stereo system. Speaker wires don’t get plugged into the wall outlet, so they don’t carry the same high level of current as a normal power cord. Speaker wires carry whatever level of current comes out of the amplifier. A typical 100 watt amplifier powering an 8 ohm speaker would produce about 4 amps at 30 volts, which most people would not feel.
If the installation is a simple one, if it does not require running wires through walls or floors, and you do not have an especially powerful sound system, there should not be any safety issues. An electrician would not usually be needed to hook up speaker wires in this type of installation.
However, if you are going to open a wall or floor, be aware that you might contact other wiring without knowing it and create a fire or electrical safety issue. In that case, or if you have any fear or concern about safety, it is best to speak to an electrical professional.
