Subwoofer not getting any sound from the sub. It was playing befor now it stop how can i fix this?

Audio subwoofers are used to augment the sound quality that is released by stereos and other audio component systems. As a result of actively using subwoofers, the sounds projected from the sound systems (such as music and voice) not only become louder, but also have a fuller output. Subwoofers, however, are not immune to problems. These issues often result in distorted sound.
Issues Among the most common problems of audio subwoofers is the loss of their bass effect while playing music or other sound files. The majority of people that experience this problem do so because they have installed their subwoofer on a different sound system than the one where it was originally installed. Additionally, there are scenarios where the subwoofer does not produce any sound. b> Troubleshooting b> Subwoofer issues are typically caused by one of two things: improper settings or broken receivers. You can troubleshoot the lack of bass or other sound effects that decrease the quality of sound by checking and adjusting the settings of the subwoofer as well as your audio system. Although subwoofers work on almost all types of audio systems, some have to be adjusted to ensure quality sound while utilizing them. Broken receivers, on the other hand, have to be replaced with new ones. b> Significance b> Fixing subwoofer problems proves to be important, not only because it will increase your enjoyment while listening to music, but also because utilizing a subwoofer improves the audio system's overall performance. When subwoofer issues go ignored, there is a tendency for the audio system to become overworked, as the user likely works the controls on the audio system rather than using the subwoofer's settings. As a result, additional audio problems may arise due to playing at full-blast volume and making other unnecessary adjustments to compensate for the lack of a subwoofer. b> Recommendations b> One way of handling subwoofer issues is by reviewing the owner's manual, paying special attention to the speaker settings. Different audio systems have their own recommended settings to ensure quality sound and that all the effects can be felt and heard while the sound file is being played. If the manual does not provide any recommended settings and/or adjustments, tweaking can be done on the audio system's subwoofer menu to create your preferred sound. Through tweaking, you will be able to find the desired quality, as well as detect and correct any unnecessary noises and vibrations coming from the subwoofer. b> Maintenance b> Audio subwoofer problems can be prevented by regularly cleaning and maintaining both the subwoofer and the audio system where it is connected. The speakers should be dusted off periodically to ensure clean release of sound and the wiring should be checked for open exposures. These exposures should be immediately repaired to prevent further damage. Fix a Subwoofer b> A subwoofer, or a "sub," is an important part of your overall sound system, whether it's in your home or car. A sub's most important quality is bringing out sounds you can feel rather than just hear. However, they are also susceptible to wear and tear from overuse, and the sound quality will be greatly affected by this. Here are some steps to fix a subwoofer.

Check with your manufacturer's Tech Support Web site. Usually with a subwoofer, the problem lies with the voice coil, which might just be burned out. These are usually fixed by sending them into the manufacturer, so determine how much you want to spend to repair it versus how much it would cost just to buy a new one. Roam through the Tech Support forums. It's likely that someone had the same problem as you with your sub, and you can run the symptoms past a few other consumers to see what diagnosis they found. Identify the specific problem if you can. You can look for tips to fix this problem on the manufacturer's Web site, or if you're technically savvy, you can try opening the sub and looking at it yourself. Two major manufacturers of subs include MTX and MK Sound. Check the bronze-colored coil underneath the foam cover. Note whether it looks worn, burned, warped or distorted. This may be the cause of your sub sounding fuzzy or muffled, which means it needs replacement. Look at the fuse inside the speaker and test it if you know how. This is a likely problem that causes your sub to power up improperly, play sounds at about half the volume or intermittently fade in and out. If the fuse is discolored or shows a short, you'll need to replace it.

Hello,

Are you plugging the sub into a 3.5mm jack or USB?
Have you tried to plug the sub into the speaker jack?
The sub works on another computer?

Bad sub or bad jack?

I hope this helps!

Turn the out put leval down on your sub, End the reciever, I was turn up to high,End that will cause it to cut out.

The sub channel will be switched off. You need to find the speaker settings, locate the sub channel settings and switch it on.

• Yea, you blew the voice coil. Pressing on the cone where you are is hitting the spot that is making the coil connect again. Just like a shorted wire. Sometimes you can bend it and get a connection. You are gonna have to replace the sub.

• If you have any comments please feel free to leave them here.
• Hope this helps and thank you for using FixYa.

Take it to a real technician. Sounds like you've proven the internal amp is shot.

You probably have too much hooked up for the size of your power supply which is presumably a small car battery. You either need to get:

A) New, better bigger battery.
B) Capacitor in series with battery.
C) Both of the above.

It sounds like you are describing an earth loop problem. I won't go into detail in this post, but try an isolation test first. disconnect everything from the reciever except the sub and try connecting say a BATTERY powered mp3 player or cd player to minimise connections to the electrical mains earth. you could also isolate things by taking your sub to a friend's house and trying it on their system.
If it is an earth loop use a process of elimination to find out which two pieces of equipment causes the earth loop. then apply filtering.
you can buy earth loop isolation transformers for about AU$26 and I've used one on my sub myself. Theyhave RCA (phono)plugs on each end and they connect inline with the signal cable to the sub amp.

as for the thumping sound it might be the speaker protection circuitry cutting off the amp to protect the subwoofer speaker from damaged. This might be triggered if the earth loop sound is causing the sub amp to overload and clip.

Failing this there might be a dried out overheated electro capacitor in the amp circuit causing the hum. Hav a chat to your local electronics person, who should be able to spot it!
Hope this puts you on the right track
Happy Hunting!

One way to check the operation is to connect a source directly to the inputs of the sub.

A CD player will work fine. Connect the out puts of the CD player to the inputs on the sub. Play a CD.

If you get music from the sub, then no problems with sub.

If nothing, sub has problem.

Could be

A Dead amp.

A Dead speaker.

Velodyne products usually need to be returned to them for service.

Cost is unknown.

I have the same problem. My guess is that the subwoofer coil is messed up. You MIGHT have to get it recoiled. But before you do any of that get someone with a sub to play their sub in your car, if it works.... then your sub is messed up, if not.....then your amp is messed up ( trial and error ). Today i noticed my subs rubber surrounding is crooked, that may be the problem for me. Also when I press down on the sub it makes a sticking sound, like something came loose. So once i get everything opened and out ill let you all know the solution. Good Luck!
