Steps to Test Speaker wires through Multi-meter: 

Step 1The first step starts with turning off all of the linked equipment or working with the speakers. Yes, we are talking about all of the equipment’s and the reason for that is to keep yourself and the speaker safe.

If you have not turned off the speakers and performing the entire work, then chances are higher that you will end up facing damages or a short circuit into the speakers. In the journey of fixing one problem, you can invite several other issues into your life by only one mistake. Hence, it would help if you cared about that.

Step 2The second step will be to figure out all of the wires in your speakers and remove them. Yes, we are talking about the wires connected to the box or anything else, and it has to be removed. The reason you should do it is that it’s mandatory for both negative and positive wires.

After that, make sure the wires that are connected with the stereo receivers also have to remove. IF the lock mechanism is connected, don’t try to remove the cables. Instead of that, press the clips together and then remove the wires accordingly. You can remove the wires with the help of screwdrivers.

Step 3The third step will be to create a circuit after removing the wires for the speakers and stereo. At one end, twist the speaker cables together. Now, you have successfully made a close circuit that will help you for continuous testing.

While you are twisting the wires, make sure not to twist them together firmly. Otherwise, the wires will tear apart, and you have to buy a new one.

Step 4The third step will be to use the multi-meter, and for that, you have to turn it on. Depending on your needs, you have to set the Ohms by adjusting the dials. The reason for using this option is to check out the resistance quickly. Also, it’s the mandatory part that helps to perform anything on the wires.

Step 5The fifth step will be to test the wire, which is the crucial step. The bare speaker’s wires of the circuit have to touch with the multi-meter two probes. Therefore, the process needs to be implemented on the wires that you have not twisted.

Check on the multi-meter and see if there is any infinite resistance that showed up. If it’s happening, then it indicates that the wires have a cut or break issue. Therefore, you have to remove the whole wire and replace it with a newer one.

A small resistance on the multi-meter ensures that the speaker wire is working fine. However, there is another issue inside the speakers, and it could be the sound issue.

Test Speaker wires in the car through a battery

We have discussed one method in the above portion that is possible with the help of a multi-meter. However, not every person has a multi-meter in their home. Therefore, we have come up with this second method to test the speaker wires in the car with the help of Batteries. So, let’s begin talking about it.

First of all, you need a 9-volt battery. The battery can be of any company as it never makes any significant issues. After getting the volt-battery, make sure to connect the speaker leads with the volt-battery. The negative wires have to connect with the battery’s negative, and the positive has to connect with the positive side of the battery. If you hear a pulse sound, it indicates no issue with the speaker wires.

Note: Apart from testing the Speaker wires, you can also test the tweeter and speaker itself with the help of a volt battery. Connect the wires in the same way and check if the pulse is generated. If it’s generated, then it’s a clear indication that the speakers and tweeters are working correctly. However, make sure to connect the volt battery for less time with the speaker; otherwise, it will cause significant damages to the speakers.

Best car speakers for bass without a subwoofer

Some car owners want to buy car speakers without a subwoofer but it can be a heft task as you need to know what to look for in them. Read our buying guide before making the purchase.


How do I test speaker wires with a multi-meter?

First of all, you have to unplug everything that is connected to the speaker. Secondly, the wires have to connect with the batteries. Thirdly, set up the DC voltage setting and place your digital multi-meter on it. Fourthly, the multi-meter has to connect when one wire is attached to the other. Fifthly, check out the positive and negative numbers. Lastly, return everything to its desired place.

How do I know if my speaker wires are bad?

For each speaker, you have to check the speaker wire connection. If the speaker wires are poorly connected, you will see that the terminals are loosely connected with the cables.

How do I know if my car speaker wire is working?

You can check the speaker wire is working perfectly or not by considering the Multi-meter or 9-volt battery. If the battery method shows you a pulse sound, it indicates that the speaker wire is working. On the other hand, you will experience a slight resistance on the multi-meter that indicates that the speaker wires are working correctly.

How do I test speaker wire?

For testing the speaker wires, you have the option of testing it with a multi-meter or a 9-volt battery.
