Terminals & Lugs

A loose or undersized lug wastes the current your wire was chosen to carry, so the end of the cable deserves as much attention as the run itself. These ring terminals come in 1/0, 4 and 8 AWG, with Sundown Audio 20-packs in red and black and Full Tilt Audio 10-packs for each gauge.

Matching Ring Terminals to Your Wire

Buy terminals by wire gauge first. A 1/0 lug is made for 1/0 cable; forcing smaller wire into it leaves a loose crimp, and trimming strands to squeeze larger wire into a smaller barrel throws away copper. Next, check the ring hole against the stud it will bolt to, whether that is a battery terminal, a distribution block or a fuse holder, so the lug sits flat with full contact. Many amplifiers use set-screw inputs that take bare wire, so lugs usually land at the battery, ground point and fuse holder.

Red, black and color coding

Sundown Audio's red and black versions make positive and ground easy to tell apart at a glance, which speeds up troubleshooting and helps prevent a reversed connection. Full Tilt terminals come in 10-packs per gauge for smaller jobs.

How to Get a Solid Crimp

  • Strip only enough insulation for the wire to bottom out in the barrel.
  • Use a crimper built for the gauge, such as a hammer or hydraulic tool for 1/0 and 4 AWG.
  • Give the terminal a firm pull test; it should not move.
  • Slide on heat shrink before crimping, then shrink it over the barrel and jacket.

Some installers also solder after crimping. Either way, a clean, tight mechanical connection is what keeps resistance low.

Completing the Connection

Pair your ring terminals with the matching gauge of cable, such as 1/0 AWG power wire or 8 AWG power wire, and color-matched heat shrink. Terminals at the battery see the full current of the system, so if you are adding a second unit from our batteries collection, order extra 1/0 lugs for the interconnect. Everything else for the install is under Cable & Wire.
