Can I Use an Instrument Cable as a Speaker Wire?

The question often arises whether it's feasible to use an instrument cable, specifically a guitar cable, as a speaker wire. This article will delve into the details of why and why not, providing insights and practical advice.

Understanding the Differences

Simple guitar cables and speaker wires are designed for entirely different purposes, and attempting to use one in place of the other can lead to issues with performance and durability.

Low-Level vs. High-Power

Typically, guitar cables are designed to handle low-level signals, which are weak and are usually between 1 to 5 millivolts. On the other hand, speaker wires are intended to carry the high-power output from an amplifier to a speaker, which can be significantly higher—often ranging from 100 to 500 watts.

Speaking of Power

A typical guitar-to-amplifier cable carries a power level that is less than a tenth of a milliwatt. Such a current is insufficient when dealing with the substantial power output of an amplifier to a speaker. The wires in a guitar cable cannot handle the high current required to drive speakers at significant volumes, leading to potential damage and poor performance.

DIY Experiment or Experiment for Disaster?

While some enthusiasts might dream of using guitar cables for a unique stereo setup, this approach comes with significant risks. Here's a step-by-step guide that entails modifying guitar cables to mimic speaker wires, but we strongly advise against it:

Unscrew the metal jacket of the guitar cable to reveal the positive and negative wires. If you have a coiled wire, unscrew it to access the internal components.

Attach speaker pins to the ends of the wires or solder solid copper wires to each end. Make sure to properly connect the ends to the speaker terminals at the back of your stereo.

Acquire two guitar amplifiers, preferably Fender Deluxe Reverb or smaller Crate amps, and set both their volumes to 0.

Connect the speaker cables to the guitar inputs and turn on your stereo to music. Gradually increase the volume on one side, then match the volume on the other side.

For an enhanced setup, consider using two speaker columns with 3 12-inch or 4 10-inch speakers. Ensure the speakers are wired correctly and the amp has an external speaker jack. Hook up these columns using straight guitar cables.

Be aware that this setup is not recommended for those without extensive knowledge and expertise. The risks of damage and poor audio quality are high, and you might face significant issues when trying to use a guitar cable for its original purpose.

Using Instrument Cable for Speaker Wired Speakers

Technically, yes, but it depends on the type of speaker. Instrument cables are suitable for speakers with their own built-in amplifiers (powered speakers) because these devices don’t need the signal wires to power the speakers. However, they may not work well for unpowered speakers, which require relatively thick, low-resistance wires. Heavy lamp cord or specialized speaker wire typically works best for such applications.

While there might be rare scenarios where using instrument cables makes sense, it's generally not recommended due to potential damage and compromised audio quality.

Conclusion

It is crucial to use the appropriate type of cable for both instruments and speakers. While the thought of repurposing guitar cables into speaker wires might seem intriguing, the risk of compromising your audio quality and equipment integrity is too high. Always use the right type of cable to ensure optimal performance and longevity of your equipment.
