Speaker cable with 2 wires provides fast, simple connections to most AWG systems to help bolster your sound experience. You can use 16 gauge 2 conductor speaker wire for larger, more professional systems, while a 12 gauge 2 conductor speaker wire is suitable for most home audio needs. However, 14 gauge 2 conductor speaker wire is ideal for systems that need more durability than a 12 gauge. Before you buy, make sure you are taking into account the size of your system and the area of coverage you’re looking to accommodate.
