Speaker Wire Gauge Calculator

Professional wire gauge calculations for optimal audio performance

Wire Length (One Way)— distance from amp to speaker

Speaker Impedance— typically 4Ω, 6Ω, or 8Ω

Amplifier Power (per channel)— max output in watts

Wire Material— CCA has ~60% higher resistance

Maximum Acceptable Power Loss: 5%— industry standard is 3–5%
