When you’re installing car speakers, you want your wires to match the rest of your system so it sounds like a cohesive whole. But which gauge is right for car audio? You see, different wire gauges have different electrical resistance. That means they handle alternating current at different voltages.

So which size is right? In general, larger-gauge wire has lower resistance and works well with amps that are lower in output impedance. If you’re running multiple subwoofers or amplifiers from one switching amplifier, a larger-gauge wire will probably work best for you.

On the other hand, smaller wires have higher resistance and may require more power from an amp to sound good. If you plan on upgrading your wiring in the future or connecting additional components to your system, a smaller-gauge speaker wire may be best. Here’s everything you need to know about car audio speaker wires.

After lots of research based on customer feedback, We think the best gauge speaker wire for car audio is InstallGear 14 Gauge AWG Speaker Wire. With it is made from a premium stranded copper and a tinned copper braided shield to provide the highest quality audio cable materials for speaker wire. Consider GearIT Pro Series 14 AWG Gauge Speaker Wire as an alternative if you're still undecided. Other suggestions on this list are definitely worth considering, and we've put up a useful shopping guide to help you decide!

What Factors Should You Consider While Choosing best gauge speaker wire for car audio?

Getting to the best decision for a product purchase may take a bit of time. In a nutshell, we're available to serve you with your product problems at all hours of the day and night!

You can rest assured if you consider the following points before selecting best gauge speaker wire for car audio:

Resistance

Before you purchase any speaker wire, you must first look at its resistance. A speaker wire with a lower resistance means that the amplifier is able to send more power through the coil. Because speaker wires of this type have low resistance, they are shorter in length and thicker. It can cause a dangerous audible effect if the resistance exceeds 5% of the loud speaker's impedance.

Wire Material

Any speaker wire's wire material is made up of the conductor metal contained within its wire cover. Copper is a common choice for speaker wires due to its low cost and high conductivity. Copper can oxidize if it is exposed to oxygen, which can cause higher resistance. Copper is still the most efficient conductor of speaker wires. Although gold can conduct well, it's quite expensive so most people don't consider buying speaker wires with this metal.

Gauge

It is also known as the cross sectional area of the wire. The wire gauge is often also known as its thickness. You should be aware that speaker wire is generally thicker if it has a lower gauge than the other. Two acceptable gauge standards exist: the American Wire Gauge and the Standard Wire Guage. You should purchase a lower gauge speaker wire if you plan to place your speakers more than 50 feet from the amplifier. This will allow you to keep your resistance low.

Connectors And Wire Type

You can get speaker wires with or without connectors. It's your choice whether to buy a bundle or a raw wire package and choose your termination. If you do that, make sure to purchase a wire stripper/cutter. If your speaker uses circular sockets, a banana plug will work best. However, a pin connector is required for spring clip terminals (square-shaped clips that clamp onto the wire and slide up). Although you can use either bare or plated wires, they are difficult to manage.
You don't have to be concerned about the wire type if you run speaker wire between desk speakers or monitors on bookshelves. You should look for units rated CL2 and CL3 if you plan to run wire within your walls. You should only use wire that is rated for direct burial if you plan to run wire outdoors and/or underground.

Inductance

Inductance is the resistance that results from a change of electrical current. Inductance is a property of all conductors, including speaker wires. You might encounter resistance more frequently if your speaker wire is used in an area where electricity voltage fluctuates. To minimize resistance, it is best to use speaker wires of a lower gauge.

Capacitance

Capacitance is the capacity of conductors for retaining very little electricity. When electricity travels through conductors, small amounts of electricity are retained along the length of each wire. It can cause adverse reactions if there is an excessive buildup of electricity in these conductors. This can lead to an increase in resistance and damage to your speaker. You can reduce the likelihood of excess capacitance by using shorter speaker wires.

Price

It is a matter of debate whether higher-priced speaker wires are better than those at lower prices. There is general agreement that speaker wires of higher quality will perform better than lower-priced models. This conclusion comes from extensive listening tests, as well as research by audio professionals. The best speaker cables are those that fall in the middle price range. While the least expensive may be more durable, they will not have a greater impact on the audio quality. You should save some money on more important gear, like amps and receivers or interfaces.

Length

The measurement of the system is an important part in selecting speaker wire. However, this step has far greater impact than just visual appearances. The length of the wire will affect how resistant it is. Even though the effect isn't usually noticeable at long distances, it can significantly reduce sound quality. The longer wires can pick up interference from radios and static, which could affect a listener's enjoyment.

FAQs

What type of wire is best for a gauge speaker?

The best type of wire for a gauge speaker is stranded copper or silver-plated copper cable. The thicker the wire gauge, the better it will be for carrying the power of the speaker. If using for a high-powered speaker, make sure to use a thicker gauge wire (14-16 gauge) for best performance.

What gauge speaker wire should I use for my car audio system?

The gauge of speaker wire you should use for your car audio system really depends on the power of your system. Generally speaking, the higher the power of your system, the thicker the gauge of wire should be. For most car audio systems, an 18 gauge speaker wire is sufficient. If your system is more powerful, you may want to consider a 16 gauge or 14 gauge for optimal performance.

Is the gauge of wire important for car audio systems?

Yes, the gauge of wire is important for car audio systems. The thicker the wire, the more current it can carry. This means that thicker gauge wires can provide more power to your speakers, resulting in better sound quality.
