Noise from woofer


I am not able to get any sound from my speakers for the past few days. There is a constant noise from the woofer and the speakers. I have creative 4.1 speakers. The problem started all of a sudden. I am confused. Please help me out.

Re: Noise from woofer

I've been running a single aw1251t with a hct2150 for a few months and it sounded awesome. all of the sudden, i change my head unit and began playing music as usual and i smelled that burnt wire smell. could i have unwiitingly over powered the speaker? if so, is it cheaper to replace or repair?

Re: Noise from woofer

Double check all of your cables, but it sounds like the power supply may have died. If the sound is like a mains hum, then the power supply will need to be replaced. Is it an internal or external one ? If it's internal, are there any fuses accessible ?

Sounds obvious, but double check the speakers are all correctly plugged in, by removing and re-inserting them. Check the volume controls and and other switches too. Try plugging headphones into the audio outputs to confirm their is actually a signal present, as the speakers may be fine, but the source may be faulty or its configuration changed.

Subwoofer problems

My sub woofer makes constant buzzing noise

Jan 04, 2014 | Car Speakers & Subwoofers

1 Answer

I have a subwoofer in my truck. 2 speakers in a box with an amp. One of the subs blew to a song that just came on. the volume was high. Sounds distorted. Any way to fix?

Sounds like the voice coil of that woofer overheated and melted while it was turned up too far. Now that area rubs on the magnet or pole piece internally and makes noise.

No you generally can't fix that except for a few high end woofer brands that have field replaceable voice coils that you can buy. Most subwoofers physically bottom out and sounds really bad before experiencing thermal damage like that. Sounding bad is a warning sign that it's being overloaded.

Note that woofers have 2 different types of overload conditions that can cause damage.
1. Over excursion from deep bass that moves the woofer cone too far and damages the suspension. This is clearly audible. Proper box design and user knowledge will prevent this.

2. Thermal limit. This is the published power rating that the voice coil can absorb without damage. Things can melt or fail entirely if this is exceeded.

Either of those issues can cause the noise you are hearing. Without a more detailed description of what happened or how it sounds before, during and after this is much detail as I can provide. But.. move the woofer some by hand, do it evenly pushing straight down evenly on both sides, not too far, go about half way through it's normal movement. If it clearly rubs and makes noise internally then the voice coil is damaged or if has some debris stuck in there. Most woofer are not serviceable.

There are many other factors that affect the longevity of the woofer, such as
  • Ambient temperature too high
  • Limited air flow has inadequate woofer cooling
  • UV exposure can make the surround material brittle
  • Proper enclosure design is needed to acoustically and physically supports the woofer to prevent bottoming out, particularly at the system resonant frequency.
  • Amplifier distortion can kill speakers even when rated far below the woofers max wattage.

A "whining" sound just started

Based on your description of when the sound gets worse I am assuming the noise is coming from the engine area and not the speakers. The noise sounds like it is the power steering pump and it is probably low on fluid. If it is in fact coming from the speakers in the car replace the spark plug wires and plugs and that should resolve the problems.

I have a few problems. i have 2 amps and 4 subs. first problem is when i connect one amp to my speakers it just hisses and crackles. this never happened before. when i turn up the gain to try and get...

The first amp, sounds like there is straight power going through the gain instead of it being limited. The second amp...hook the other subs up to it and see if it sounds ok. If so, then the subs are messed up. If it sounds the same, make sure the subs are connected correctly.

Wierd problem with my subwoofers please help

It sounds like your RCAs are pickin up noise somewhere, are your rca cables next to your amp power wire? this could be the problem. Just recheck your signal wires and make sure they aren't close to any significant power cables. Also does the noise only come from your subs or your car speakers to? If it comes from all your speakers you may have a headunit problem... hope this helps

RF P1 12" subs voice coils blew

lost cause, take em back if you can.
Next time make sure you break them in, don't overpower them, make sure the crossover is set up right and if it sounds distorted.... it's bad on your woofers.

Very loud odd noise coming from radio speaker

There might be 2 probs
  1. The wires soldered to the the CD/FM input/output wires might have come loose leading to short/sparks causing the loud sound(constant).
  2. If there are any sockets requiring plug-in they may require cleaning with pure alcohol or rectified spirit(unlikely).
  3. The wire leads going to the speakers may be partially loose........................sodeep

Woofer making horrible noise! HELP!

Think as an expert... Probably from my experience repairing woofers etc... the cone (1) or the spider (2) isn't well glued onto the woofer skeleton(or both???) The woofer cone must be absolutely centered or else you will get those clicks in low frequencies(you also get them in higher frequencies but you can't hear them!) I must say that it is very difficult to repair a woofer by your own. I suggest to return it back where you bought it and take another one (i suppose that you have a guarantee ha?).
