GLS Audio 500 feet Bulk Professional Speaker Cable 12AWG 4 Conductor Black - 12 Gauge Patch Cord 12/4 Gauge Wire - Pro 500' Spool Roll 12G 4 Conductor Bulk - Speaker Wire

GLS Audio speaker cables are manufactured with the highest grade materials in the industry. The copper wire is rated in AWG spec which stands for "American Wire Gauge". This GLS Audio speaker cable is a professional-grade solution designed for high-performance audio setups. This bulk cable (500 feet on a spool) features true 12 AWG (American Wire Gauge) 4-conductor wire, ensuring high fidelity and power transfer with minimal signal loss over long distances. The cable is built for demanding environments, featuring a thick, durable, and flexible 10.5 mm rubber jacket that protects the internal wiring while remaining easy to install and route.

Its professional construction provides reliable quality for a variety of audio applications. The AWG rating was developed by the USA as a result of some wire manufacturers stating their wire was a certain spec when it really wasn't. You'll notice most imported wire and cable manufacturers will rate their wire in "G" or Gauge (not AWG). The "G" rating can be used for any wire size.
For example: A 12G rated cable may only be equivalent to a 18AWG cable (or worse). There are no regulations or specifications on "G" rated cables. How can you determine if a "G" rated cable is the same spec as an AWG cable? Unfortunately, you can't unless you test the power loss per foot. Sometimes the weight may be an indicator.
For example: GLS Audio 50ft 12AWG cables weigh about 4lbs whereas most of our competitors weigh about 2.5 lbs. This may be a result of the copper wire gauge not being true AWG.
