How To Measure Speaker Wire Size

To figure out how much speaker wire you need, run a string from your receiver or amplifier location to each of the speaker locations. If unsure what size, measure the speaker wire tabs with a ruler.

To choose the right speaker wire, we need to know the length and how much current they will have to transfer so that we can select the correct gauge.

How to measure speaker wire size. Switch on the meter and set it to measure ohms on the lowest range. 12 for longer speaker wire runs: The wire size most commonly used in car audio systems ranges from 4awg to 22 awg.

Take the measuring tape and hold it on the top of the speaker driver. Most speaker manufacturers list an impedance rating on the speaker label or the packaging. Audiophiles should always wish to minimize speaker cable resistance.

The length of the speaker wire also affects the performance of your speakers. Simplified speaker wire size chart Step 1, check the label for a nominal impedance rating.

To measure the impedance of a speaker youll need a multimeter (test meter with multiple functions) or a dedicated ohm (resistance) meter. There are a lot of ways to measure a speaker wire size. American wire gauge (awg) is a standardized system established in 1857 used to measure the diameter of wires.

This nominal impedance rating (usually 4, 8, or 16 ohms) is an estimate of the minimum impedance for typical audio ranges. I would go with 12 to 16 awg as suggested. Choosing wire sizes there are a few exceptions, but here are safe gauges to use (in awg):

Strip the speaker wire (about 3/8 to 1/2 is fine) and twist the ends tightly to keep the strands in place. Measure the diameter of wires with precision scientific vernier calipers by enclosing the caliper jaws on either side of a wire and checking the scale for a measurement. This is why the thinest wire has the largest number.

(yes, 10awg would be even thicker, but then you start running into other problems with. Hold the hook of the measuring tape over the edge where the speaker. American wire gauge (awg), also referred to as just gauge, is the system used mostly in north america to classify speaker wire by the size of the diameter, or size of the speaker wire.

Determine the gauge of the outdoor speaker wire needed. Your stereo or amplifiers power output (usually listed as watts rms) the ohm rating (impedance) of your speakers; Figuring out car speaker sizes can be a little confusing.

To get the appropriate gauge always measure the distance of your speaker from your main unit or amplifier. The size of speaker wire you need is based on 3 things you can easily check: American wire gauge (awg) is a system of numerical designations of wire diameters where the thicker and less resistive the wire is, the lower the gauge number.

Read on to learn why. You can use a common wire stripper, however, to determine the diameter or the gauge size of the wires. 12 for shorter speaker wire runs:

You can use the standard wire gauge, also known as the imperial wire gauge or as the british standard gauge, or the american wire gauge. In the mobile audio world, it helps to think about the size of car speakers as more of a category than an actual size. Get the correct sized quick disconnect crimp terminals needed.

Determine the size of your speakers baffle cutout diameter. How to connect speaker wire to car or home speakers using crimp terminals (quick disconnects): Specifically for speaker wire, the most common gauges available are 12, 14, 16 and 18.

Switch on the meter and set it to measure ohms on the lowest range. The actual impedance is fairly close to this value within this. A speaker wire's resistance needs to be at least 5% of its speaker's opposition to the alternating current, in order for it to have reliable performance.

This usually occurs at a frequency between 250 and 400 hz. Use a conversion chart, such as the one provided under resources, to find the wire gauge based on diameter. However, if youd like a simplified answer heres a chart to fit the needs of most people.

Originaly the gauge represented the number of holes the wire had to be drawn through. The n gauge wire diameter d n in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39: Wire was drawn through a large hole, then a smaller hole, then a smaller hole, etc.

Most wire strippers have a series of round holes labeled with awg sizes where you can insert the wires. Measure the string, and then add a few extra feet (to provide some slack for easier connection to your gear). Flip your speaker over and inspect the underside of the unit.

In this case, it's usually best to follow the advice of the borg resistance is futile. To measure the impedance of a speaker youll need a multimeter or a dedicated resistance meter. Touch the test probe leads firmly against clean, bare metal on the speaker terminals with at least one speaker wire removed to avoid a false measurement.

The gauge size of wire originated in the 13th century. You not only can strip wires of a specific size but can also determine the gauge size of the wire. At crutchfield, we help customers who have questions about car speaker size all the time.

The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39:
