Summing up

Whether you love DIY projects or want to learn something new, soldering speaker wires is something you can do without being a professional electrician. This guide shows you in detail how to solder your speaker wire and provides helpful tips on how to avoid oxidation (rust).

The easiest way to solder speaker wire is to start by putting heat shrink tubing over the wire before stripping the end of the wire. Then work on the pre-tin process using the right solder. After that, you just need to crimp the wire into a banana clip, solder the crimp, and to wrap it, wrap the crimp area with shrink wrap to prevent oxidation.

What materials are needed to solder the speaker wire?

Before you start soldering speaker wires, it's important to have all the materials and tools you need to avoid unnecessary delays and interruptions.

Here is a list of materials needed to solder the speaker wire, which you can easily buy from a hardware store or online:

Soldering iron
Suitable solder
Flux suitable for solder
Wire cutters or wire strippers
Correct speaker wire
Heat-shrink tubing
Heat gun or alternative heat source to shrink tubes

What are the recommended fluxes and solders?

KappZapp7 works best on copper or copper when combined with Kapp Copper Bond Flux.
KappAloy9 is best suited for aluminum, aluminum alloy or copper when combined with Kapp Golden flux.

What is the procedure for soldering the speaker wire directly to the speaker lugs?

Soldering speaker wires to speaker leads may seem like a technical challenge that requires the help of mechanics or technicians, but it's not. With the right instructions and the right materials and tools, you can solder the speaker wire yourself.

Follow the instructions below to quickly and easily solder your speaker wires:

Step 1 – Turn off the power of the sound system first.

Step 2 – Then be sure to unplug it from the electrical outlet. Before proceeding, make sure there is no power running through the sound system.

Step 3 – Slowly begin to separate the ends of the new wire a few inches down. Then proceed to stripping the ends of the wires. Always place heat shrink tubing over wires before soldering.

Step 4 – Using a heated soldering iron operating at the correct temperature, apply a small amount of Kappa flux to the wires. Do not overdo it. The purpose of the flux application is to get rid of the oxide coating, for this a minimum amount of flux is sufficient. (1)

Step 5 – It is best to place the soldering iron at a level below or below the wires to ensure that it reaches the ideal temperature for soldering.

Step 6 – The flux will begin to boil and change color from the original to a darker, brown hue as soon as the wire starts to heat up. To solder the wires, touch the solder wire to the speaker wire and the corresponding tabs. Try not to melt the solder with a soldering iron, as this will destroy all attempts to solder the speaker wires. (2)

Step 7 – Wait a few minutes for the heated solders to cool completely. Use a damp cloth or Q-tip to get rid of flux residue. Once the seam has dried well, place the heat shrink tubing over the seam using a hair dryer.

Step 8 – Connect the ends of the new speaker wire to the amplifier.

Step 9 – You have now completed the soldering process. Just fire up the sound system and enjoy to your heart's content.
