Does Splicing Speaker Wire Reduce Quality?

Systems are typically designed to work with specific speaker wires, and these wires usually come in pairs. Splicing involves cutting a wire and attaching the ends of two different wires together. This article will provide you with information about how to correctly splice wires, why splicing is recommended for some systems, and what the benefits are of not doing it.

Want to add a little extra length? Splicing is a great option. The same goes for replacing the wire with one that’s longer. For extended runs, this might be your best option. But now let’s get into splicing!

1. Does Speaker Wire Length Affect Sound Quality?

Speaker wires shouldn’t suffer from interference as long as the wire length is below 100ft. However, over longer wire lengths you may see quality issues and potential interference.

In a particular situation, it is best to use thicker wire. 16-gauge wires are a good choice for lengths of 100ft or less. Any wire over 100 feet should be 14 or 12-gauge.

2. How To Affect On Overall Sound Quality Splicing Speaker Wire?

Much like how two people will disagree on how sounding cables split, so too do people have differing opinions on the matter of splitting speaker cables. For audiophiles, it is plausible that these splits may have a negative impact, whereas for only one who more casually appreciates sound, splitting cables is not likely to create a problem.

Splicing speaker cables can be a smart way to extend cables without noticing. Splicing can cause issues, so always make sure you know what you’re doing when you do it.

3. How Does Splicing Speaker Wire Work?

Splicing is as simple as connecting the cores of two different wires. This passes an electric signal through the cable without much issue.

There is more than one method to complete a splice, so you can choose the one best for your situation. With the right techniques and practices, all of these methods can result in a high-quality splice.

Here are some methods by that you can perform a splice by using:

  • First of all the Soldering method
  • Then the Crimping method
  • Or The Wire nut method

Quality splicing can be achieved by using any of these methods. Soldering may last the longest due to the added durability and strength of the connection, but it is also the most complicated and not everyone will know how to solder or even own a soldering iron.

For the easiest splice, either uses a wire nut or crimping method. Below, we will walk you through the wire nut method step-by-step.

The Wire Nut Method:

  • You should Strip ½” of the wire coating off one end of each wire.
  • Then twist the wire pairs together.
  • By using a Wire Nut (on Amazon), feed the twisted wires into the opening.
  • Twist both wires and the nut down till both wires are secure.
  • After applying the electrical tape to the newly spliced wire, coil it up neatly and carefully tie off with a square knot (on Amazon)

In case the process is done correctly, then you shouldn’t have to take worry about audio interference from the splice.

While it is tempting to strip the wires, wrap them in electrical tape and twist them, these are unreliable. If done improperly it can lead to an electrical short which will ruin your system. Approach this splice with caution!

4. What’s the Best Speaker Wire?

Speaker wire is often extravagant and has plenty of marketing lingo. In the end, any speaker wire can carry a signal to a destination without any interference.

Some speaker wires are better than others, but it’s not a big deal. Overall, the cheap speaker wire will not hurt your sound quality.

There are a few potential issues with using speaker wire; it is an antenna for electromagnetic waves, and thus interference can be picked up. The only way to avoid this is by using shielded speaker wire.

With some speaker wires, you may still need to spend a little more money for a high-quality build and quality. Just because any speaker wire will work, doesn’t mean you shouldn’t purchase one with a durable and high-quality build.

This wire from GearIT of 14 AWG should be an appropriate choice for most speaker wire needs. It is durable and made using quality materials that will last long.

5. What Do you Need for Splicing?

Want to know how to perform a splice yourself? You can do that pretty easily. You can use tools already in your home or make one for yourself if you don’t have any lying around.

You will need high-quality speaker wire, such as InstallGear Speaker Wire (available on Amazon), to get the clearest and highest quality from your cables.

For lengths over 100 ft, plan to purchase a higher gauge wire since 14 to 12-gauge wires are more appropriate for longer distances.

6. Is Thicker Wire Better for Speakers?

People argue on whether or not we should use thicker gauge speaker wire. Those who believe in audiophiles argue that it will reduce interference.

It’s a constant battle for quality. Wire thickness or cord length doesn’t matter, but the presenter’s voice needs to be the only sound coming out of the speakers.

Thicker wire, like 12 AWG wire on Amazon, isn’t worth the effort if you’re just wiring speakers in the same room or two. Splicing wires is much harder with thicker wire.

You should usually use a thick wire gauge if you have a long speaker run. In other cases, it’s overkill and most likely unnecessary.


After reading this article, you should have a better understanding of speaker wire and how it affects sound quality. While it’s true that splicing speaker wire can reduce quality, it’s not necessarily a deal-breaker. If you’re careful and use the right tools, you can still get great sound out of your speakers. Just be sure to test the connection before you commit to it. And if all else fails, there’s always the option of buying a new speaker wire.
