5 Best Subwoofer Cables Reviewed

If you’re a true sound buff, chances are you prefer to listen to your music of choice using a subwoofer.

A loudspeaker designed specifically for picking up lower-frequency bass and sub-bass, it makes audible the sounds that a typical speaker cannot generate.


When you spend a lot of money on an expensive sound system and amplifier, it’s important to take the same amount of care with choosing your connective wires.

You don’t want to cheap out on this just because it might seem like a small and insignificant part of your setup.

Just as the design of the speaker determines how good your music will sound, the quality and composition of the subwoofer cable you connect to your amp also impact the quality of the audio produced.


The materials used, the wire’s flexibility, it’s housing, and cross-section can all influence whether or not you obtain the superior sound quality that is expected from listening to music through a subwoofer system.

Below, we’ve listed several options for cables available right now, from manufacturers that we think provide a high-quality product. Our buyer’s guide will help you decide which one to go for, and the frequently asked questions section should answer any queries you may have.

Best Subwoofer Cable Buying Guide

RCA or Subwoofer Cable – which do you need?

RCA cables originated as a channel to transmit signals between phonographs and amplifiers in the early days of radio.  Nowadays, they have undergone a major transformation to be utilized for connecting AV signals between the entertainment and sound systems we use at home.

TVs, DVD players, video game consoles, and amplifiers all make use of these cords. 


A lot of subwoofers on the market use RCA connectors, but some cable manufacturers have developed a standard RCA wire further with additional features. The advanced design is what separates a so-called subwoofer cable from its RCA counterpart. 

Subwoofer cables are used specifically to connect an audio amplifier with a speaker that has been designed to reproduce sound signals of a lower frequency, up to a hundred Hertz. Whether you need a pair of wires or a single RCA cable depends on the system you are using.

Cables referred to as “subwoofers” might have more tightly woven fibers in the wire’s mesh shield, or even feature an additional second or third shield made of mesh or foil. Certain wires have gold-plated connectors, too, which improves sound conduction and protects the cable from corrosion. 

If you’re looking for a wire for a subwoofer, then you’ll want to seek out a specifically named subwoofer cable.  This helps achieve clarity and high quality sound resolution when you’re listening to music. A thicker cable will always offer a better signal transmission. 

Cable Length – Does It Matter? 

A subwoofer cable that is longer than twenty feet is likely to incur electromagnetic interference.  This is particularly if it crosses over other electrical wires when connecting to your sound system. 

Such interference generates a low-level hum when your subwoofers are in use, which can be particularly annoying when you’re trying to watch a movie or listen to some music. In short; the shorter the cable, the better! 

However, if the set-up of your entertainment system, amp, or speaker calls for a long cable for whatever reason, there are ways to avoid EMI. Try and find a cable that utilizes a dual shielding method through braiding, to insulate against the interference. 

Is Your Connection Shielded? 

The best subwoofer cables will incorporate one, if not several, additional layers of shielding in order to protect the delicate conductor cores at their center. These shields, usually made out of mesh or aluminum, will also work to protect your wire from interference. 


If you need a longer wire for connecting a subwoofer and an amp, ensure that the product you choose features at least one additional layer of protection.  The wire will be even better if it is braided or made from nylon, as these keep the wire durable for longer. 

Thickness and Flexibility 

A good subwoofer cable strikes the careful balance between thick and flexible, sturdy and pliable, solid and bendable. It should be wide enough that it won’t wear down and impact the connection’s strength or signal transmission but still move freely and with ease. 

Depending on the material your wire is made from, it will have a longer lifespan and be more receptive to bending.  This is especially true if it has a PVC coating externally or is braided in design. 

Pressure Points

All quality cables will make use of a split-tip center pin design in both connector ends.  Please ensure just the right amount of pressure is created between the input and the output. This makes for a stronger quality of the signal that won’t dip in and out during transmission. 

If the ends are gold-plated, that’s even better.  It will protect your cable from corrosion through consistent use and allow you to use the wire time and again without a loss of quality in sound. 

Frequently Asked Questions

What kind of cable does a subwoofer use?

The majority of subwoofers utilize what is known as an RCA cable, so named as it was developed by the Radio Corporation of America. This title identifies any standard coaxial cable featuring the recognizable RCA push-in connectors. 

A specifically named “subwoofer” cable refers to a wire that is used to connect an audio amplifier to a speaker.  It recreates the lower-frequency sound signals that normal speakers cannot produce. 

Is underpowering a subwoofer bad? 

The problems that can occur as a result of underpowering a subwoofer don’t actually stem from the specific act of not supplying the speaker with enough power. This just causes the sound to play weakly, and it won’t pick up as many low-frequency sounds. 

What usually happens when a speaker is underpowered is the user might alter the level of amplifier gain.  Increasing it in order to try and make the amplifier “louder” and thus increase the volume of your music. 


Unfortunately, doing so will overwork the amp and transmit what’s known as a clipped or distorted signal. This attempts to produce sounds from the subwoofer that it isn’t capable of producing, and leads to overheating and eventual burnout. 

The moral of the story is this: if your subwoofer isn’t sounding as loud as you would like. Don’t try and rectify this problem by turning up your amplifier’s sound gain, as you could cause your speaker to blow out.

Does cable length affect sound quality?

The length of the cable you use to connect your amp and subwoofer won’t influence the sound quality on its own. However, if it’s longer than twenty feet, it’s likely to experience electromagnetic interference, which leads to the presence of a low hum.

While this doesn’t necessarily impact the quality of the sound, it can be annoying to deal with when you’re trying to listen to music.  We recommend sticking to a cable that is just as long as required to connect your amp.

Can you extend a subwoofer cable?

If you’re looking to extend the length of an RCA cable, it’s possible by using what’s known as a “female-to female barrel connector.”  This allowed the use of multiple cables between the amp and the speaker. It would probably be easier just to buy a longer cable, though!

Why does my subwoofer have both a left and right input?

If your subwoofer has a port for two inputs labeled left and right, the manual it came with will usually tell you which port is best for a source, like an amp.  The only requires the input of one wire to establish a connection.

Can I use a coaxial cable for my subwoofer?

You can certainly use a coaxial cable and a subwoofer cable interchangeably, but it might not offer you the same sound experience. For instance, digital coaxial cables and video cables have a standard impedance of seventy-five ohms and are fully interchangeable. 

However, RCA cable connectors intended for use with audio systems may not necessarily have seventy-five ohms of impedance.  So always check before you make the switch to see if the wire will be compatible. 

Does a subwoofer need power?

Passive subwoofers are so-called because they require additional power from an external amplifier or audio-visual receiver, much like a traditional speaker would. As a result, the amplifier or receiver you use needs to supply enough power to reproduce those low-frequency sounds.

An active or “powered” subwoofer is both a self-contained speaker and amplifier, housed in the same product, and requires no external power.
