How to Pick and Use a 4 AWG Car Ring Terminal

4 AWG is a common size of conductive wire, and ring terminals are used to cap this type of wire. These ring terminals are designed to make it easy to connect 4 AWG wire to a battery or another power source. 4 AWG ring terminals are the perfect choice if you want to make sure that the audio in your car is robust enough to impress all of your friends.

What types of ring terminals are offered?

A few different types of rings terminals are made for 4 AWG wire. Each kind has unique attributes, and a few of the different offerings include:

  • Heat shrink: This kind of audio device has a thin sleeve of shrinkwrap on the end. Once you have connected your cable to its terminal, you can use a heat gun to make a solid seal around the point of connection.
  • Screw ring: These kinds of devices are somewhat bulky, and they feature central screws. Instead of using a crimper, you use a hex wrench to secure these kinds of ring terminals to 4 AWG cable.
  • Bare terminal: These kinds of ring terminals are similar to their heat shrink counterparts. However, the ends of these devices are bare, which exposes the conductive copper that is used to carry an audio signal.
How do you pick ring terminals for your setup?

The kind of ring terminal that's best for your setup is partially dependent on the tools you have on hand. If you have a crimper, then heat shrink ring terminals or bare terminals might be best. But if you only have a hex wrench, it might be better to go with screw ring terminals. If a ring terminal is listed as 4 AWG, it is designed to fit 4 AWG cable.

How do you connect and crimp a 4 AWG terminal?

After you've decided on ring terminals that fit your needs, there are a few steps that you will need to follow to use these devices. These steps include:

  • Step 1: Use cable cutters to cut a length of 4 AWG cable that is sufficient for your needs.
  • Step 2: Locate the slot on your cable cutters that is marked "4 AWG." On some cable cutters, there will be separate slots for stranded and solid cable.
  • Step 3: Measure about 1/4 inch up the cable, and strip the insulation from the cable with the cable cutters.
  • Step 4: Insert the exposed end of the cable into the terminal, and use a crimping tool or hex wrench to secure it in place.
  • Step 5: If your ring terminals have heat shrink, use a heat gun to shrink the wrap around the cable.
