DC Audio 12 AWG OFC Speaker Wire – Oxygen Free Copper Wire for Speakers and Subwoofers

Good speakers and amplifiers can only perform as well as the wire feeding them. The DC Audio 12 AWG OFC Speaker Wire is built for serious current delivery, clean signal transfer, and long-term reliability whether you are wiring door speakers, subwoofers, or a full system in your Squarebody.

Built from oxygen-free copper (OFC), this is true performance-grade speaker wire designed to reduce resistance and support better amplifier control compared to lower-quality wire. For classic trucks where you may be running longer wire paths through doors, under carpet, behind trim panels, or back to cargo-area amplifiers, wire quality matters.

The matte blue and black translucent “Get On Our Level” cable gives it a premium look while delivering the performance DC Audio is known for.
