Category Guide & Buying Information Fitment, power & selection tips
Shop oxygen-free copper (OFC) car audio wire in multiple gauges and lengths for amplifier power, ground, speaker and custom electrical installations. Compare conductor size, cable length, strand construction and jacket specifications for the exact product.
Choosing OFC Wire for Car Audio
- Gauge: Size the conductor for the circuit’s current demand, run length and application.
- Power and ground: Use appropriate OFC cable, terminals and circuit protection for amplifier and charging-system wiring.
- Speaker wire: Choose conductor size and length around the speaker load and installation path.
OFC describes the copper conductor material; it does not replace correct wire sizing or fusing. Review each product page for the exact gauge, length and construction before ordering.
