If you’re having trouble with your speakers, or just want to make sure they’re working properly, you can test them using a multimeter. In this guide, we’ll walk you through the process of how to test a speaker with a multimeter. With the right tool, such as the Milwaukee GIDDS2-288935 Digital Multimeter, you can easily measure resistance, voltage, and current to determine whether your speaker is functioning correctly. Let’s get started!
| QUICK LOOK: I use a multimeter to test speaker resistance, voltage, and current starting with resistance (ohms) to check the coil’s health. Then, I move to voltage and current tests to ensure power is flowing right. If my readings don’t match the manufacturer’s specs, it’s time to replace the speaker. |
How to Choose a Multimeter for Speaker Testing

Step by Step guide on how to test a speaker with a multimeter
Step One: Measure Resistance
The first thing you’ll want to do is measure the resistance of your speaker. To do this, turn on your multimeter and set it to the ohms function (Ω). Then plug one end of a test lead into the positive terminal of your multimeter and connect the other end to one side of your speaker.
Now, take the other test lead and connect it to the negative terminal of your multimeter. This will complete the circuit and allow you to measure the resistance of your speaker. The reading on your multimeter should now be displayed. For a more accurate measurement, you can use a tool like the Amprobe AM-500 Multimeter. Write this number down for later reference.
Step Two: Measure Voltage
You’ll want to measure the voltage of your speaker. To do this, turn on your multimeter and set it to the volts function (V). Then plug one end of a test lead into the positive terminal of your multimeter and connect the other end to one side of your speaker.
Now, take the other test lead and connect it to the negative terminal of your multimeter. This will complete the circuit and allow you to measure the voltage of your speaker. For more accurate testing, tools like the best multimeter for car battery can come in handy.
Step Three: Measure Current
You’ll also want to measure the current of your speaker. To do this, turn on your multimeter and set it to the amps function (A). From here it is a bit different , you have to connect your speaker in series with speaker. Plug one end of the test lead into the positive terminal of your multimeter and connect the other end to one side of your power supply.
Now, take the other test lead and connect it to the negative terminal of your multimeter. This will complete the circuit and allow you to measure current of your speaker. You’ll also need a power supply that can provide at least twice as much voltage as required by your speakers in order for them work properly during testing. If you want to know more about how to measure amps with multimeter then I have also made a separate guide on that for you.
Step Four: Compare Results
Now that you’ve measured the resistance, voltage, and current of your speaker, it’s time to compare these readings with the manufacturer’s specifications. If your readings are within the acceptable range, then your speaker is functioning correctly. However, if any of your readings are outside of the acceptable range, then you may need to replace your speaker. I used the Amprobe AM-510 during my testing it handled everything from voltage checks to continuity tests without a hitch.
Safety guide while testing speakers with multimeter
When testing speakers with a multimeter, always be sure to take precautions to avoid electrical shock. Be sure to unplug your power supply before making any measurements, and never touch the probes of the multimeter while it is plugged in. Also, be careful not to short out your circuit by mistake. I’ve found that using the Amprobe 37XR makes the process much safer and more straightforward, especially for beginners.
Conclusion of Testing a Speakers with a Multimeter
Now that you know how to test a speaker with a multimeter, you can rest assured knowing that your speakers are in good working order. If you ever have any doubts about the condition of your speakers, be sure to run a quick test to find out. I’ve used tools like the Klein MM600 for reliable readings they’re accurate and built for safety. And always remember to use caution when testing electrical equipment, as it can be dangerous if not done properly. If any of your readings are outside of the acceptable range, then you may need to replace your speaker.
FAQs
Q1: How do I measure the resistance of my speaker with a multimeter?
To measure the resistance, set your multimeter to the ohms (Ω) function. Connect one lead to the positive terminal of the speaker and the other to the negative terminal of the speaker to get the reading on your multimeter. The resistance should match the manufacturer’s specifications.
Q2: How can I measure the voltage of my speaker?
Set your multimeter to the voltage (V) function. Then, connect one test lead to the positive terminal of your speaker and the other to the negative terminal. The multimeter will display the voltage reading, which you can compare to the speaker’s specifications.
Q3: What do I need to test the current of my speaker?
To test the current, set your multimeter to the amps (A) function and connect your speaker in series with a power supply. Make sure your power supply provides at least twice the voltage required by your speaker for accurate results.
Q4: How do I know if my speaker is working properly after testing?
After testing the resistance, voltage, and current, compare your readings to the manufacturer’s specifications. If the readings fall within the acceptable range, your speaker is functioning correctly. If any reading is outside the specified range, the speaker may need replacement.
