Subwoofers make popping noises because of squared waveforms, incorrect cone signals, or overpowered setups. The distorted sounds indicate a mismatch between the input and output based on the speaker’s specs. If you run more than one sub, there must be enough power to reach all of them to avoid popping sounds.
How do I fix my subwoofer popping sound?
A popping or crackling noise is being heard from a speaker or Turn off the stereo receiver. Ensure the speaker wires are properly connected to both the speakers and stereo receiver. Turn off any nearby electronic devices that may be interfering with the speaker sound.

Why is my speaker making a popping sound?
Speaker crackling is almost always caused by a connection problem. The first thing to do is to check the wire connections between the amplifier and the terminals on the speaker itself. If the wire has a tendency to get moved around, perhaps by a cat or dog, it’s a possibility something has come loose.
Why does my Sub Pop when I turn it off?
There is energy stored in the woofer (inductor) or in the capacitors of the amplifier, which causes a back-EMF when the circuit is cut, much like when you turn off a fluorescent light; sometimes you see a spark at the switch. Any transient tends to make its way to the speaker, causing a pop.
Can a blown subwoofer be fixed?
To fix your blown subwoofer you’ll need to take it out of your car, fix or replace any damaged parts, and glue/wire it back together. This process can range from easy to very difficult, depending on the problem.
How long does a subwoofer last?
What is the lifespan of a subwoofer? Typically, you can expect a good quality car subwoofer to last for 4 to 10 years with some lasting even longer than that.
How do I stop my amp from popping?
The easiest way to achieve this is installing a capacitor (500 to 1000 microfarad) on the “remote in” wire to the unit. This would allow the unit to stay on a few seconds more, which should give enough time to the amp to turn off before the other equipment.
Why is my subwoofer making a rattling noise?
Subwoofers often rattle when there are loose components, but it they can also rattle if they are underpowered or overpowered. It’s important that you do an inspection on your subwoofers before each and every performance. Subwoofers are crucial devices for your home theatre system.
Will a blown amp turn on?
Every car audio system includes the fuse to prevent damage to the audio system in case of any short circuiting. So, if the fuse is blown then you wont be getting any power to the amplifier, and the amp will not turn on.
Why is my subwoofer smoking?
Clipped, unclipped, dirty, clean, it doesn’t really matter how the power goes into the woofer, it is going to cause the voice coil to heat up. Both the smoke and the smell are a result of those resins on the coil returning to liquid and eventually a vapor.
Why does my subwoofer make a loud noise?
Subwoofer hum or buzz is a low-level noise that can be present whenever a passive or powered subwoofer is turned on, whether or not it is playing. This 60-hertz hum is a result of being plugged into an AC wall outlet. Usually, all it takes is a change in the way the subwoofer connects to power.
Why does my amp go into protection mode when I turn it on?
Some amps go into protect mode if they get too hot, which can prevent a permanent failure. The common cause of overheating is a lack of airflow. If the amp is located underneath the seats, or in another confined space, that may cause it to overheat.
Why does my Sub not hit hard?
Acoustics: Sometimes it may seem like your subwoofers are not hitting hard enough, but it is actually the acoustics of the room that are making your speakers sound bad. If your subwoofer sounds good when the volume is low, but does not hit hard enough when you increase the volume, your amplifier is too small.
How do I know if my voice coil is damaged?
Blown Speaker Symptoms Distortion at Normal Volumes – If even at moderate volumes you hear hiss, static, and fuzz, then you have one of two problems on your hands. You either have loose or damaged voice coils or you have a torn cone. If you turn up the volume the problem should get worse.
Are dual voice coil subs better?
Car subwoofers are manufactured with either a single voice coil (SVC) or dual voice coil (DVC). The difference is the DVC sub offers more wiring options to better match and take advantage of the amplifier. A dual voice coil sub does not directly perform better than the same sub with a single voice coil.
Is it worth repairing a subwoofer?
A: The short answer to your question is no, the repair is likely not worth it. The price/performance ratio of subwoofers has improved considerably in the last decade, so finding a subwoofer that matches or beats the AS 20’s specifications—8″ driver, 60 watts RMS, 33 Hz to 140 Hz frequency response—is not too tough.
