How many watts can 16 gauge speaker wire handle?

How many watts can 16 gauge speaker wire handle

Before we go into how many watts a 16 gauge wire can handle, let’s look at what kind of thicknesses that comes in.

The unit for measuring the thickness of wires is a gauge, and each gauge is represented by a number. Generally, smaller numbers present thicker wire numbers, and higher numbers are used to tell thinner wires apart.

Now the other big question is which wire size you should choose and which one is the right one for you.

So, for the most part, in cars especially, the ideal size should be 18 gauges, and if you are planning to use longer wires, the length should be 2 gauges, and this is to avoid losing any sort of power.

Many online websites have specialized tools that allow you to calculate the right gauge, and one site in particular that has a gauge calculator is

This will recommend to you the right size based on the power and the speaker Ohms. So in some cases, maybe a 12 gauge might be suitable for you or an 18 gauge one; this calculator will help you calculate it more effectively.

Now coming to the real question, which is how many watts can a 16 gauge wire handle. Well, to understand this, you need to keep in mind watts can change dramatically if you alter the voltage or current involved.

The number of watts can be calculated with the formula, Wattage (power) = volts * amps; typically, a 16 gauge wire shouldn’t be given more than 15 amps, and by adding a suitable value for the voltage, you can easily determine the watts required.

You can make a speaker wire wattage chart if you are dealing with more than one size of wires.

How to pick speaker wire?

How to pick speaker wire

Let’s face it, picking a car audio wire isn’t all that easy when you are bombarded with a ton of options and especially those options that are soo closely competitive.

Buying Guide: Best Speaker Wire For Car Audio

Best Speaker Wire For Car Audio

Before you put your foot down on the accelerator and make the buying decision, there are some factors you need to consider closely because everything should be according to your requirements.

Type of material used

The type of material manufacturers choose to design the wires is extremely important, and the thing is, not all wires are built the same, and the type of material significantly has an impact on conductivity and its ability to deliver output and sound.

Copper is 100% the best conductor for electricity, and it is the standard that all audio cable look up to. Some companies are choosing to opt for copper clad aluminum which is, although a cheaper alternative to copper but has slightly different properties than copper.

Manufacturers are using other wire materials like aluminum and zinc, but all those are inferior to copper due to their low resistance and a small number of benefits provided.

Choosing the right gauge

You all must have noticed whenever you are looking for a car audio cable, wires are offered at different gauges but determining which one is the right one is important.

Let’s learn how to select the best gauge speaker wire for car audio. The first thing you should do before choosing a gauge is to look at the back of your car speaker or know its resistance or impedance.

We have already compared the gauges of each of these six wires in our car audio speaker wire gauge guide in the comparison chart, so we recommend you to check it out if you’re interested to see it.

Remember this always when you want to select the right gauge:

  • Eight-ohm speakers: 14AWG up to 200 feet, 12AWG for 200+ and 16-18AWG for 50 feet or less,
  • Six-ohm speakers: 16AWG for 50 feet or less, 12-14AWG for 50+ length
  • Four-ohm speakers: 12AWG for 100 feet or less, 8-10AWG for 100+ length


Every wire or pair of wires you end up purchasing should be marked for polarity, and that means if the wires are identical, either side of the wires is marked, which makes it easy to distinguish and makes installation easier. If the wire is multi-colored, let’s say one wire is blue and the other wire is black, they don’t need to be marked for polarity as it’s going to be easier to distinguish them from each other based on their color.

Power, Ground and Speaker Wires – What Wire Gauge Should You Use?

FAQs – Frequently Asked Questions & Answers

Although we have covered all the products and different theories regarding car audio cables, some questions always remain unanswered; we want to look at those questions.

How do you install banana plugs with your speaker cables?

If you are looking to install banana connectors with your wires, it is a straightforward job so let’s learn how you can do that. The first thing is You have to strip the whole wire first. To strip the wire, you will need a help of a tool called the wire stripper, which will help you to cleanly strip the wire.

Afterward, you’re going to unscrew one of the banana plugs and carefully push the wire inside, and again screw the tip of the plug. Repeat the process for all the banana plugs and connect your cable to your amp and the speakers and you’re all set.

What wire should you choose, Bi-wire or a single wire?

Maybe choosing the best car audio speaker wire was an easier decision for you, but what about single wire or bi-wire? Which configuration should you opt for?

Now obviously, if you own a speaker that only allows for single-wire connectors, then a single wire will do the job for you. On the other hand, if your car speakers have two sets of connections, then you can choose a bi-wire. A bi-wire has its benefits which include giving you a much richer detail and an open sound stage. It all boils down to personal preference, though, and we leave this debate for the die-hard audio cable fans.

Do audio cable terminations important?

Yes. Generally, termination is situated at the ends of the cable, and it provides you with connections to sources and speakers. Those options are commonly referred to nowadays as banana plugs and spade plugs. These provide you with their own benefits, and those include quicker and faster connections as they simply and easily plug into the terminals of your speakers. If fitted properly, they can also be a source of reliable and sturdy electrical connection, minimizing any risk of shorting. So, as you can clearly see, these terminations make your job a whole lot easier and add their own level of convenience.

Final Words

Let’s wrap up this piece with our concluding remarks. Our aim was to find out about the best speaker wire for car audio, and along the way, we reviewed six options. Each one of those options brought its own unique features, and it’s difficult to determine which one is the best because they are so different in what they offer and bring to the table, but what is important for you to know is that a good quality audio cable makes a huge difference in the sound output and overall quality of sound you are experiencing, so it’s worth giving a shot picking the right one.
