Balir 🎙️ Registered User How to prevent a speaker/amp to pop when turned ON/OFF Haiiiiii, Share Reply Quote4th June 2019 #3 nosebleedaudio Registered User
Better amps have a power on Mute relay, some have a soft start circuit.

Unfortunately, the post #2 isn't doing anything. My speakers ( Genelec 1037B and Yamaha ns10 with Pc2002) is still popping... I have a Furman conditioner and that is not helping either... If you can suggest a brand, that would be so cool! Thank you! Share Reply Quote10th June 2019 | Show parent #5 nosebleedaudio Registered User

Thank you!The Furman will have NO control over popping. That has to done/controlled Inside the amp, Between output and Speakers. Also keep in mind the popping can also come from powering up the console/mixer AFTER the amp, the amp should be Last ON, first Off.. 1 The speakers in your car are one of the most important components, not only for the in-car music experience but also for taking the call and receiving navigation messages. Accessories such as amplifiers and subwoofers only add to this experience and allow us to truly feel the music. Without them, the music can sound very dull. That’s why it is very understandable for a user to worry about these audio system parts. In this article, we’ll discuss one of the problems drivers face and how to solve the problem. Here’s Why Speakers Or Subwoofers Pop When You Turn the Car On or Off?You may have often noticed that a pop sound is heard from your speakers when you turn your car on and off. This can be caused due to various reasons linked to your amplifier. A “pop” or “thump” typically indicates that a DC step has been applied to the speaker cone. This occurs in electronic amplifiers because, when the power is turned off, one of the two bipolar power rails or the amplifier sections (a class AB amp has a positive and a negative portion) shuts down more quickly than the other. This article contains:
However, there is nothing much to worry about as long as you maintain your car’s audio system. Related:
Why Does The Speaker Or Subwoofer Pop When The Amplifier Turns On Or Off?Subwoofer enclosure in a boot of a carThe amplifier is a device that boosts the audio signals from the head units and plays them through the subwoofers. It goes hand in hand with the subwoofers. A sound from the subwoofer whenever the amplifier is turned on can be due to many reasons: 1. High Amplifier GainA pop noise is frequently heard when the gain setting on an amplifier is set too high. You may hear this when you initially start the car and the amplifier switches on. The speakers and subwoofers attached to the amplifier can be heard popping as the amplifier turns on and sends the first 6 volts via the speakers and subwoofers. 2. High Line Output ConverterThis problem is similar to an amplifier with excessive gain settings. The line output converter is powered by 12 volts, which is also occasionally used to turn on the subwoofer amplifier. That is when you hear the same pop sound. 3. Insufficient Turn-on DelayTo prevent turn-on pops, amplifiers normally contain a little delay. However, occasionally this delay is insufficient. Similar to how the DC offset disappears when the head is turned off, there is a pop because it takes the amplifier a certain amount of time to shut down once the remote wire loses power. What Causes Speaker or Subwoofer Thump In General?Current interruption is the main reason for the speaker’s popping and cracking. Audio signals from speakers are converted into mechanical wave energy via transducers (sound waves). Electrical transmissions with alternating currents make up audio signals. Sometimes, it happens due to a poor connection. A faulty connection between your amplifier and speaker driver is causing the driver to move erratically and generating interference. The faulty connection problem could be located in a number of locations, some of which are simpler to fix than others. The thumping sound can also be caused due to the amplifier. The amplifier powering the speakers is where the sound comes from. To keep their output at “zero volts” in the absence of a signal and to stabilize their performance, almost all amplifiers require some form of “feedback.” Depending on the amplifier-specific design, amplifiers require some time after power is introduced for the feedback loop to become active and start controlling the system. When the feedback loop finally “kicks in” and pushes the output voltage back to zero, if the amplifier’s output voltage (i.e., the signal applied to the speaker) starts to climb during that time, it will result in a “pop.” How Do I Fix The Speaker/Subwoofer Pop?There are various ways to fix your car speakers, depending on the reason for their popping. If it is due to a connection problem:
Note: If the issue is with the original speakers, it should disappear when different speakers are attached. If the issue is still present, it is the amplifier’s fault. Check this great article on how reasons why speakers crackle. If, however, it is your amplifier that is causing a problem, you should remove or replace your amplifier. Most modern amplifiers control the problem, and you won’t hear your speaker popping again. If you do not know what the problem is, you can try these two steps:
Wrapping UpOnce you identify the reason for the thump, it becomes very easy to sort out the issue. It’s something very common, and hence there’s no need to panic when you hear it for the first time. Just follow the steps discussed above, and your sound system will return to normal before you know it! Why does my speaker pop when I turn it off?Typically a turn off pop is caused either by a grounding issue, or just for the simple fact that the amp needs to turn off before all the other equipment.
How do I stop my speakers from popping when I turn them off?So, how do you stop speaker monitors from popping? You can stop speaker monitors popping by following this easy rule: Powered speaker monitors should be powered off first and powered on last. Additionally, you should always first turn off the system before connecting, disconnecting, or powering the speakers.
Why does my speaker sound like it's popping?Speaker popping and crackling are caused by interrupted electrical current (audio signals) or, in other words, a loose or dirty connection. To fix crackling and popping, troubleshoot the connective wires to find the problem area and secure the connection and/or replace the cable.
Why does my amp make a popping noise when I turn it off?It's because the amp was using electricity, and when you turn it off the speakers pick up the stopping of the electrical current through the amp.
