How to Test Speaker Wire with Multimeter

If you’re an audiophile, then there is a good chance that you are very particular about the sound quality of your speakers. One way to ensure excellent sound quality is by using high-quality speaker wire. But how can you know if your speaker wire is up to par? Speaker wire testing isn’t complicated, but it does require specific tools and knowledge in order to do it properly. Here at we will show you how to test speaker wires with a multimeter so that you never have any doubts as to whether or not your new purchase will provide the best performance possible!

Possible Problems with Your Speakers & Wiring


Connection problems are often the cause of sound loss or distortion. If you’re having trouble with your speakers, check to see if there is any corrosion on the connections between devices and also make sure that all cables are securely connected in order to avoid malfunctions. Corrosion can be a sign of age as well so it’s important not to neglect your speaker wires.

Grounding  Problems

Grounding problems can be caused by many different things such as bad connections, loose shielding on the wires, or poor-quality wire. All of these issues are common and easily fixed if they’re caught in time but it’s important to check for them before you do any major repairs so that problems don’t arise later. Also make sure that your speakers are grounded by using the correct type of wire.


Sometimes speakers won’t work because the amplifier isn’t providing enough power. You can fix this problem by using an external amplifier or installing a new one in your speaker system, but you’ll need to check that it’s compatible with whichever brand of speaker wires are being used before making any changes!


This might be more difficult to spot, but sometimes speakers are the issue! If you’re getting interference or static in sound from your speaker system then this could be a sign that it’s time for an upgrade. Check with a professional before replacing them just in case there is another problem at hand.

Test Your Speaker Wiring with a Multimeter

  1. Turn off All the Equipment. Make sure everything is turned off before proceeding to avoid electrical shock, which can be fatal if not dealt with quickly. Make your work area safe and free of any hazards so that you don’t have to worry about making a mistake!
  2. Remove all the speaker wires from their respective devices. It is important for safety’s sake as well as ease of testing that you remove each wire individually instead of yanking them out at once in order to help reduce potential damage or mistakes on your part. Keep track of what goes where- it’ll make things much easier when it comes time to reconnect everything later on.
  3. Connect wires together in one long, continuous strand. Be sure to use the right type of wire- speaker wire will only work properly with speakers and not for any other purpose! This way you can avoid making costly mistakes later on that might affect your sound quality. Now run it from device to device by connecting them end-to-end until you’ve connected all devices at which point they should be securely joined into a single strand. If there is resistance or “fighting” then this could indicate an issue like loose shielding or incorrect wiring so make note if this happens during testing.
  4. Setup your multimeter by inserting black lead (negative) into COM port and red lead (positive) into VAR ports as indicated on your meter. When the leads are inserted correctly, you should see a reading of either 0 or very little with no movement on your meters needle- this means that there is nothing connected to it and everything is functioning properly!
  5. Test speaker wire connections by moving from one end to another while checking for voltage readings (if any). If the multimeter does not detect anything then be sure to check the connection points as they could have come undone during testing which will require repair before using again.  If you do get a readout, try disconnecting cables at different ends in order to isolate where exactly the problem lies so that it can be fixed more easily. Be careful when messing with metal connectors since these parts might still hold an electrical charge even when the power is off.

Test speaker wire with a Battery

This can be done by using an old (or new) AA or AAA battery to provide voltage and then testing it on the multimeter for any readouts- if there are none, but you’re still encountering issues with your speakers, this could indicate that there may be loose shielding around connecting wires which will need to be repaired before they’ll work properly again!

Safety Rules Regarding Your Multimeter

Physical Inspection:

Be sure to inspect each point thoroughly by looking at how connections are made as well as checking for broken insulation or corroded terminals in order to make sure things look sound and nothing has been damaged during use. If anything looks like it might be broken, don’t attempt to test it because you could make the problem worse so have a professional take care of that for you.

Electrical Shock:

This is one where prevention is better than cure- never use your multimeter without properly grounding yourself in order to avoid any accidental shocks on your part which might damage sensitive circuits or cause injury if not dealt with quickly! Turn off all power before using and then ground by touching two metal points (such as pipes) together while testing connections just in case they’re faulty. If there’s an issue here, stop working immediately and call someone who can help out safely until everything has been fixed up so you can continue work uninhibited.

Conclusion :

Speaker wiring definitely requires some careful consideration when doing work and be sure to read the instructions on your meter before use so that you know how best to operate it. This way there won’t be any accidents or problems when testing connections, just a lot of peace of mind and confidence in knowing that everything is working as intended!
