Necessary tools to cut the speaker wire

  • Marker or pen for marking the wire.
  • Safety gloves to keep your hands in check.

How To Cut Speaker Wire?

Follow these easy procedures how to cut the speaker wire:

Step 1: Measure and mark the desired length

With your ruler or tape measure, size up the length you need for your speaker wire. Use your marker or pen to mark the cut point on the wire. Remember, it’s better to overestimate slightly than leave yourself short.

Step 2: Prepare the wire cutter or wire stripper

First, pick out a wire cutter or stripper suited to your speaker wire’s thickness. If you’re dealing with a particularly thick wire, you might opt for an adjustable wire stripper. Get your tool ready according to the specific size of your wire.

Step 3: Secure the wire

Now, firmly grasp the wire to keep it straight and taut. This is a crucial step as it prevents sudden movements that could disrupt the cutting process.

Step 4: Cut the wire

To cut the wire to size, you can also use a sharp knife and a hammer. Place the wire against a wooden cutting board, place the blade end of the knife at the desired cutting point, and then pound the knife’s back until the wire is severed. While it could require a few strokes, it’s more simpler than using a knife to saw the wires away.

Step 5: Inspect the cut ends

After you’ve cut the wire, take time to check the ends. Examine the finish for smoothness and the absence of frayed strands or loose insulation. If things are a little ragged, use your cutter or stripper to tidy them up.

Step 6: Strip the insulation (optional)

If you plan on connecting your speaker wire to terminals or connectors, you should strip off some of the insulation from the ends of the wire. Check the manufacturer’s instructions or use stripper to remove about 1/4 to 1/2 inch of insulation. Be careful not to nick the wire when stripping it back.
