Can Speaker Wire Be Spliced? – Ultimate Guide 2022

You may have heard that speaker wires can’t be spliced together. This is only partially true. You CAN indeed splice speaker wire, but you need to know more about the different types of insulation it has before you do so.

People usually buy home theater sound systems to enjoy their favorite movies and sports games in a new way. These speakers allow you in-home entertainment on par with the best theater or stadium experience.

If you need to move the speakers from the installation position, you will find that a lot of wires may come undone, and both listeners and installers could get tangled up in them.

If you are considering a wireless speaker system, it is important to know how to splice the speaker wire in order to ensure that you create an appropriate distance for your compatible setup.

How To Splice Speaker Wire What Is the Best Way?

Crimp connectors are the most secure way to splice wire. Using electrical tape separates the connection in ways a crimp is less likely to, so it is recommended to avoid it.

Crimp connections are a short-term fix to the stranded wire. A solid core wire is easier to work with, but you can still use an outer wrap of tape to prevent it from unwinding.

Outdoor speakers must be protected from the weather to ensure that the wiring and electronics don’t get damaged.

Make sure your speakers are set up properly before you start playing any sound. Follow these three steps to get started.

Step #1: Set Up Your Equipment

Before you and your partner get to the wire splicing process, you must be sure that the speakers are positioned correctly.

  • Firstly you should turn the power off to your home stereo receiver.
  • Then disconnect the power cords.
  • Unplug all the speaker wires, and examine them for quality.

If you see any wire that looks damaged or in poor condition, it should be thrown out immediately.

Assemble the speakers at the location of your choice. If you have time, think about how to disguise or hide your wiring in the living area without resorting to a wireless setup.

P….Step #2: Before Cut the Wire Measure the Distance

When you have your speakers curled up to the placement you prefer, measure the length of wire that you’ll need to connect each one to the stereo system. It is easiest just to use string or twine when measuring.

To make sure that you’ve cut the wire to the right length, stretch the string between the speaker and the system. Mark where you need to cut using a marker that is visible. Match up that length of wire flat against the floor with a piece of string and see if it corresponds.

Never underestimate how much of a certain ingredient you need. Overestimate it a little, and if you end up with leftover bits, use them in something else.

Stereo cables often do not come in the desired length, so it is important to make a sufficient length. If you have wires that can be easily spliced, it is best to label their ends now by writing the name of the speaker or amp on its end.

Step #3: Strip the Wire To Attach the Connectors

Take the first set of wires that need to be spliced. Place the terminals (the ends) next to each other, keeping both positive and negative terminals together.

To succeed, speaker wires are needed to be in phase. You can use a battery to see if you have one wire or two.

  • Slowly and gently drag the end of the wire against the side of the battery.
  • If you connect the red wire to the positive terminal on the rocket ship, you should hear a tone. If you don’t, take a moment to scan the area and see if someone accidentally connected the black or blue wire to either one instead.
  • Then After identifying this information, you may need to confirm the wires are connected to the appropriate ports.

To prepare the wires, use wire cutters to strip off the exterior insulation or jacket. Four ends should have at least a quarter-inch of copper exposed when you are finished.

Begin by wrapping the joint with electrical tape. Take the crimping section of the wire cutters and use it to squeeze the tubing around the wire on both ends of the joint.

Perform the same for the positive connections.

Check the joint by tugging on the wires to make sure it is tightly in place. Double-check the connection for any redundancies with a battery.

Step #4: For make the Connections Shrink Apply Heat

After connecting the wire ends with the crimp connectors, apply a heat source to the outer layer for easy connection. Your best option is a blow dryer set to high heat.

You can also use a hot air gun, but it is important not to set the temperature too high or low.

  • Hold the wires in your off-hand, just more than a few inches below the connection though applying the heat.
  • Then slowly rotate the wires so that you may start shrinking the crimp equally on all sides.
  • The tight-fitting casings are very secure and should be waterproof.

These crimps have a bump of solder in the center to help secure connections and will create a strong bond.

Basically, what you do is strip the wires, attach connectors, and extend the lengths of wires to different lengths.

Step #5: Reconnect the Speakers

With the wires correctly spliced and in place, you can then connect your speaker to the stereo amplifier, receiver, or surround sound system.

You might want to invest in speaker wire connectors for a more secure connection. These make attachment easier, as the speaker wire simply plugs into a binding post or spring clip.

Now that you’re connecting the speakers, there are some additional steps to follow such as installing the speaker wire connector.

  • Ensure you’re not stripping too much wire, as the conductor may need at least 12 mm.
  • To remove the outer section of the banana plug or the connector’s manufacturer, twist and pull away.
  • Loosen each of the locking fasteners on each plug, being careful not to remove any screws entirely during this step.
  • Insert the speaker wire into the connector with as little pressure as possible. If it is too loose, stop and try again. Once you feel the wire touch the end of the chamber, insert it a little bit farther.
  • Tighten the locking fasteners by turning the screws in the other direction.
  • If you want to use a banana plug, pin, or spring clip on the binding post instead of using a direct wire connection, you need to replace the outer section of the connector.

After you finish setting up your new stereo system, be sure to test it to ensure all the speakers work correctly.

If your speaker or receiver isn’t working properly, check the connections there.

How to Splice Speaker Wire with Wire Nuts?

The wire twist connector is an option to consider if you need a quick fix. They’re not as reliable for speaker wires, but they can be used for connecting wires in a home or commercial building.

To make twist connectors, you must combine both wires before finalizing the work. Use fingers to bring the two wires together and form an “arrow” shape.

To create electrical connections, you would use wire lugs to combine two conductors of the appropriate size. Once they are connected, seal them with electrical tape to prevent a short circuit.

If you don’t secure the twist connector, it could come loose. Therefore we recommend securing it with a crimp rather than a push and twist lock.

How I Can Solder Speaker Wires If I Want to Do It?

What If I Want to Solder My Speaker Wires?

For a secure finish, you can solder connections. You do not want to leave them unprotected because any moisture or skin contact could damage the equipment or cause a personal injury.

You need to have electrical tape that goes a couple of inches past the soldered connection and ensure you have proper insulation for the connection.

The process of splicing two-wire connections together is simple. All you need for the task is a soldering iron and solder. The details on how the task is executed will vary depending on your speaker setup, but the purpose remains the same.

The NovelLife TS100 is a professional tool that has an adjustable temperature and can be used by most people, even if they don’t have cosmetology expertise.

If you once have the equipment, the following steps can let you solder the connection successfully.

  • Cut the speaker wire and strip it so there is at least a half-inch of slack. You need to make sure that there is enough room for the solder to work.
  • Bend the wire into an “X” so that its two ends are facing in opposite directions.
  • Wrap both ends firmly around each other, and tightly twist the cord to make it completely overlap the other.
  • Heat the soldering iron.
  • Once the soldering iron is heated, connect the wire to the component and run it under the tap for a few seconds.
  • You can apply enough solder so that it strem entirely through the wire.
  • You can solder the wires on this side of the joint until it’s fully saturated.
  • While the solder cools for about a minute, test fit the box’s innards.
  • Constrict the joint with electrical tape to make it as strong as possible. Start the wrapping at an angle and make sure not to overdo it by caring for a safe level of tightness.

Make sure that no part of the copper wire is exposed. Otherwise, it might create a short circuit and damage your speakers or other system components.

What Is the Best Way to Strip Wire?

A kitchen knife is not the best tool for wire stripping. There are specific tools that were designed to do this effectively and more accurately.

Sharp blades can cause problems with the wire connecting to the speaker by cutting it.

I use a StarTech crimping tool for RJ45 and RJ11 cables. The wire stripper and crimping tool make it easy to set up any wire type.

In certain brands, there are different holes for gauges on the outside of the wire stripping tool. You need to put a length of wire in and then tighten it enough to hold it in place before pulling it out.

It’s challenging to strip wire initially because you need a delicate balance between pressure and pulling.

When you try to strip a wire, make sure not to apply too much force by squeezing the wire stripping tool. If you do, it is possible that you will snap off some of the thin wires in the process.

The speaker wire is tough to work with. So, for now, why not try to practice on something else. You’ll run into fewer errors with your wiring work that way.


Yes, the speaker wire can be spliced. However, it is important to note that the quality of the sound may be affected by doing so. If you are looking to achieve the best possible sound quality, it is recommended that you use a single piece of speaker wire. However, if you are Splicing speaker wires is not difficult and can be done with a few simple tools. With a little bit of care and attention, you can splice your speaker wire without affecting the quality of the sound.
