Using American Wire Gauge standards, the gauge of stranded wire is determined by the total area of the conductor.To calculate this you would take the area of each strand and add it together. This area, in square mm, then determines gauge.Diameter is not as critical with stranded wire, this is due to the tiny air gaps between each strand. Diameter may fluctuate with strand size and how tightly wound the rope of the cable is.The smaller the number, the larger the wire, until you reach zero or aught (0). From zero, you then have double aught (00), three aught (000) and so on.Based on AWG, the true gauge of this cable is #3, larger than traditional 4 gauge  We've compared several popular 4 gauge amp kits from other manufactures. The above chart displays the manufacture and the calculated gauge based on area.All cables tested were labeled as 4 gauge. The X axis indicates gauge by area and where each cable's measurement placed itself on the American Wire Gauge scale.Several brands barely reached the required area of 8 gauge. Every amp installation kit clearly states these critical specs: Wire type - CCA or OFCThese materials are commonly used, but not commonly stated when shopping online. Know what you are purchasing. Both metals are capable of performing up to their rated loads.American Wire GaugeWire gauge is crucial to powering your system correctly. Undersized cable will create unsafe conditions and may shorten your amplifier's life
