You've invested in a new amp and speakers — now eliminate the weak link in your signal path by upgrading to high-quality StreetWires Super Cable® speaker wire. This 50-foot spool includes enough multi-stranded pure copper wire to connect the front and rear speakers in almost any vehicle.

The wire's low profile design ensures easy installation. Its non-gripping wire jacket is flexible enough to pull through your car, yet rugged enough to handle life in a rough automotive environment. This 16-gauge wire carries the signal more efficiently than the thinner 20- or 18-gauge wire often included with car speakers. Warranty: 1 year.

on the positive and negative terminals.

Product Research


Overview: StreetWires Super Cable is a high quality alternative to basic factory speaker wiring and offers sonic improvements as well as easier installation. The cable features  plus symbols (+) that run the entire length on one side of the cable so you can easily identify the positive or negative lead.

Fine-stranded high conductivity copper windings: High purity copper with very fine stranding provides lots of surface area for unrestricted power flow and maximum sound quality.

Blue Ultra-Flex jacketing: The blue jacket is tough and flexible so it can stand up to the harsh environment in your car.

Low profile parallel design: For easy installations, Super Cable's low profile shape makes runs in tight areas a breeze. 

Zero-grip insulation: The insulation jacket doesn't stick to the wire so it can easily bend around tight corners to make installs smoother.
