18/2 AWG Two Conductor Speaker Wire - Clear - 250&';18 AWG Speaker wire is commonly used in home theaters, digital audio, and stereo speakers. 18 AWG Speaker wire is not built for nor rated for in-wall usage. How is it built? Well, speaker wire is built from finely stranded tinned copper conductors. The conductors are then covered with translucent PVC insulation. To help identify polarity, Pacer added a positive (+) symbol to one of the conductors. This insulation is made to be flexible which makes installation easy.How do you use 18 AWG speaker wire? They start by selecting the correct gauge. The gauge can be determined by determining how long the wire needs to be. It&';s a good idea always to add a few extra feet. This leaves room for error and keeps the run from becoming too tight. After you know the length of the wire, you need to consider the power requirements of your application. Once you know the length of your run and the power requirements, you can choose the correct gauge wire for your job.
