How To Test A Subwoofer With A Multimeter
How to test a subwoofer with a multimeter
Connect your multimeter's positive and negative probe to the voice coil's positive and negative terminal, respectively. Finally, turn on the multimeter and switch it to its Ohms setting to determine your subwoofer's resistance. There's a simple method to test a subwoofer, and it's through a digital multimeter.

How do you diagnose a broken subwoofer?
Test the sound at a low volume to listen for whether your sub has been blown. If it is distorted, you have a partially blown subwoofer, and if there is no sound at all, it is completely blown. If the subwoofer is receiving its signal via a cable, then check the cable before rushing to conclusions.

The car subwoofer will produce distortion free sound for the car audio system. Typically without an amp the standard speakers and the subwoofer output won't produce a louder sound and the bass frequencies will be flat.
How do I test my subwoofer output?
The receiver sub-woofer output is line level. So to test you could connect to a line level input (e.g., Aux) of a separate amplifier and listen through headphones or speakers that can handle low bass frequencies while playing something with low bass content through the receiver you are testing.
How do you check speaker coils with a multimeter?
To use the multimeter, set it to read resistance. It may have an ohms symbol for this setting. After this, place the leads of the multimeter on the speaker terminals. You can touch the positive and negative leads to either terminal when reading resistance.
Should I run my sub at 2 or 4 ohms?
A subwoofer with a lower electrical resistance produces a louder sound than one with a high electrical resistance, which means that 2ohm subwoofers are louder than 4ohm ones. Although louder, 2 ohm subwoofers are also more likely to produce a poorer quality of sound due to its' power consumption.
How do you check speaker polarity with a multimeter?
Using a digital multimeter set it to the 200 millivolt dc setting ensure the wires don't make
What does a blown fuse look like in a subwoofer?
If the fuse is blown, the filament will be disconnected at one of it's ends. Sometimes this is noticable, sometimes it isn't. Look carefully and see if the ends are visible. Try tapping the fuse and quickly look to see if the filament is bobbing around like a lose wire.
What would cause a subwoofer to stop working?
If your subwoofer stopped working, there's a good chance it was blown. To check, unplug the subwoofer and plug it back in. If it still doesn't work, try switching the input from AUX to SUBWOOFER on the amp. If that doesn't work, the subwoofer is probably blown and needs to be replaced.
Will a blown sub still make noise?
If you experience no sound from it, it is completely damaged and requires you for a replacement. However, if you can hear partial sound or audio, then it means a partially blown speaker cone. You can also physically inspect the damage, test the movement of subwoofer by removing the cover.
How do I know if my amp is blown with a multimeter?
To check this, you simply locate the power fuse for your amplifier, set your multimeter to resistance, and place your probes on both ends of the fuse. If the amplifier produces a negative reading, the fuse is bad and needs to be changed.
What does a blown bass amp sound like?
The most common aural indication of a blown speaker is an unpleasant buzzing or scratching sound, by itself or roughly at the pitch of the note the speaker is attempting to reproduce.
How many Ohms should my subwoofer be?
The answer to this question is subjective and depends on what you are looking for in a subwoofer. A 2-ohm subwoofer will offer louder output than a 4-ohm subwoofer, making it the better option for those looking for higher volumes. However, a 4-ohm subwoofer may offer better sound quality.
What frequency should I test my subwoofer?
85 Hz Sinewave Some subwoofer models do not feature a built-in test tone generator, so an 85 Hz test tone is useful to help set the phase adjustment correctly.
How do you tell if a subwoofer is blown without hooking it up?
Physically inspect the speaker. Also, if you gently exercise the speaker cone by pushing on it (being careful not to puncture the cone with your finger or push it much further than 5 millimeters), you should hear almost nothing. Blown speakers will make a scraping or crunching sound with any movement.
