StreetWires 1/0-gauge set-screw Power Rings provide a quick, crimpless installation. Just insert the bare wire end, then use a small socket screwdriver to tighten the heavy-duty, gold-plated locking screw for a strong connection to your amp's power and ground cables.

Set-screw rings are precision machined from high-conductivity brass with an attractive, corrosion-resistant Diamond Plate Nickel plating. You can reuse these durable rings if you upgrade your system or move your components to a different vehicle. Warranty: lifetime.

Works great!

These power rings are built really well. Fit over my 0 gauge wiring perfectly.

Hands-on research

What's in the box?

  • 2 Crimpless power rings (one has a red band and the other has a black band)
  • Two 2" Lengths of clear heat-shrink tubing

Product Research


Overview: StreetWires Power Ring Terminals ensures that your system's components will get more power with less voltage loss and heat buildup than your average terminal connection. Two-step termination provides the cleanest connection with the best power cable protection. The body of each connector is screen printed with a colored band. One connector has a red band on it, while the other is imprinted with a black band. Colored bands ensure correct polarity identification.


  • Loosen the set screw with an Allen wrench (not included)
  • Push the 1/0 Gauge wire (with approx. 1/2" of insulation stripped off end) into the lower section of the connector
  • Tighten the set screw with an Allen wrench to secure the wire
