How we selected the best speaker wire for car audio?

Speaker cables link speakers to amplifiers and radios. They are in charge of transmitting energy to the speakers, and while they do not generate sound, they have a substantial impact on speaker performance. But what is the best speaker wire for car audio? Let us investigate.

The greatest speaker wire does not have to be expensive to provide a million-dollar sound. Even the most basic cable may have your speakers going in no time. However, many speakers do not come with wiring, necessitating a trip to the store. So, whether you’re just getting started with your system or seeking to extend your current setup, we’ll explain some of the terminologies and assist you in picking the best speaker wire for car audio.

In general, the finest speaker cables for car audio are those that are particularly developed for automobile audio. While the loudspeaker wire gauge is significant, speaker wire impedance should be the most important factor to consider when selecting speakers for the greatest sound quality. Speaker wire resistance, on the other hand, varies with speaker channel length and speaker power output.

Because of the greater speaker series resistance in the same wire volume, a 16-gauge loudspeaker wire can have up to 50% more speaker wire impedance than an 18 g speaker wire at the same length. When speaker power is tripled, speaker wire resistance rises by 9% and speaker watts fall by around 6%. So, while selecting speaker cables for automobile audio, consider speaker wire length to ensure that you fulfill the speaker input power requirements.

As a general guideline, total cable resistance should not exceed 5% of the impedance of the speaker. For 2-ohm speakers, for example, 16 gauge wire is appropriate for up to a 12-foot length between both the radio and a speaker, however, 18 gauge cable cannot be more than 8 feet.

How we selected the best speaker wire for car audio

To choose the best speaker cables, we considered wire composition, gauge, and manufacturer to guarantee overall dependability. We examined over 25 suggested brands, read research publications, and analyzed first-hand user evaluations, delving deeply into the argument over the link between cable quality and pricing. We also examined our own home devices and recommended wiring that we had utilized to add a personal touch. While it is entirely up to you to evaluate if you notice a noticeable change in audio quality when utilizing certain cables, each of our recommendations will create a strong, robust connection for outstanding sound.

Considerations when purchasing the best speaker wire for car audio

There appear to be a limitless amount of speaker wires to pick from, but in fact, most wires are pretty similar when joining the majority of speakers. To choose the best speaker wires for you, you must first analyze and comprehend the terminology used by manufacturers to describe them. We’ll go through terminology like resistance, gauge, and resistance before showing you some goods we believe in.

Material and function

Speaker wire is used to link speakers to amplifiers and to connect individual speakers to supply the electrical charge signal that produces an accurate, dynamic sound. While we refer to speaker wire as a single entity, each speaker is really connected by two individually encased conductors (at least). These distinct positively and negatively strands are usually identified in some way to indicate input audio polarity so they can correctly match the same stations by + and – or generally colored red or black—on both your amplifier and speaker. This ensures that the right voltage is transmitted and received.

Copper, cerium aluminum (CCA), and o2 copper are the most common materials used in speaker cables. The variations are minor; CCA is less expensive and has somewhat greater resistance, whilst oxygen-free choices exist in a variety of grades that indicate stronger conductivity or durability. Silver and gold wire are also available, albeit the difference in effectiveness is minor. While there might be slight variances in sound—for example, the silver wire may have a tighter soprano and gold wire a rounder, warmer mid-range—the details aren’t worth the extra expense unless in the most high-end, carefully tuned systems. Although some wires are wrapped in rubber, most speaker wires are insulated with plastic such as Teflon or PVC.


The resistance of a speaker wire is the most crucial factor to consider while purchasing. Low resistance permits the wire to stimulate more of the amplifier’s power to activate the speaker’s voice coil, which is wiring beneath the driver that generates a magnetic field when exposed to electricity, causing the speaker’s cone to move when exposed to a waveform. To put it simply, a greater signal means cleaner, clearer sound.

A wire’s resistance can be affected by several factors, including height, thickness, and impedance. Impedance, measured in ohms, is frequently stated in speaker product specifications (typically 4, 6, or 8). While you don’t need to grasp the physics behind impedance to know that the volts of your converter and speakers should match, remember that the smaller the resistance, the more vital it is to look for low impedance in your wiring.


The gauge, or diameter, also known as thickness, of speaker wires is a significant distinction; the lower the evaluation number, the thicker the wire. Factors depend on the American Wire Gauge (AWG) standard, and 12-, 14-, 16-, and 18-gauge speaker wires are available, with 12 being the thickest. Thicker wires lower resistance in general, although they are only required in particular conditions.

You don’t need a wire thinner than 16 gauge if you have 8-ohm loudspeakers and less than 50 feet of cable running to the amplifier. A thicker 12- or 14-gauge wire will minimize resistance and provide a more stable, constant conduit if you need to traverse a long-distance or have low-impedance speakers. If you’re not sure what size you need, go with a thicker choice to minimize sound degradation.

Types of connectors and wires

Speaker wires can be purchased with or without connections; it is up to you whether to buy a package or a raw wire spool and pick your own termination. (Don’t forget to acquire a wire stripper/cutter if you’re doing this.) If your speaker has binding posts (circular sockets), a banana plug is ideal, but a pin connection is required for a springtime clip termination. You may use bare cables for either connection, and they can also be difficult to manage.

If you’re connecting shelf speakers or desk screens, you don’t need to bother about the cable type. If you want to run wire through your walls, search for a device with a CL2 or CL3 rating. If you’re going to run the cable outside or underground, ensure sure it’s rated for “direct burial.”


There is much disagreement on whether pricey speaker cables outperform lower-cost alternatives. The general agreement is no; listening testing and a significant study conducted by audio specialists concur that the performance of your speaker cable will most likely be consistent.

We recommend choosing a speaker cable in the center of the price range; the cheapest cable may not be made to endure, and the most costly cable may not increase the quality of your music. We recommend reserving part of your funds for more crucial pieces of gear that will have a bigger influence on your performance, such as amps/receivers, connectors, and other components.


The best speaker wire for car audio will connect your system effectively, give the correct quantity of energy, and help in perfect audio reproduction. While there are numerous cables available, it’s crucial to remember not to overthink your purchase and instead choose a mid-range solution that will meet the demands of your amp and speakers.

The cable should cost no more than 5% to 10% of your system’s budget. Of course, if you’re an audiophile eager to test the limits of each sort of wire, it might be worthwhile to conduct your own test with higher-end substances; however, many of us probably wouldn’t notice between top-quality speaker wires and less expensive options as much as we will notice the difference among music and no music.
