firt you clean the subwoofer with cleaner after that, check the subwoofer srrounding, no electrical wire ,mobile phone & electrical operated items is near ur subwoofer.
1. Do not use maximum volume of subwoofer.
2. Use only 65-85% volume of your sub woofer.

SOURCE: replacing sub speaker

I wouldn't try reinventing it by replacing the driver. Drivers and their enclosures are designed to work together. And this being a self-amplified subwoofer, there is one more piece that's electrically optimized to the rest. Don't mess with it.

Why don't you just set your receiver's individual relative speaker volume levels so the sub isn't weak by comparison to your other speakers? Weakness, as you call it, is relative.

Is your receiver properly channeling Low Frequencies to the sub? Experiment with the cutoff, too.

This problem doesn't require meatball surgery.

SOURCE: Power, but no sound

take an ohm meter and remove wires from speaker...put meter in the ohms position...you will put a lead on each of the terminals of the speaker...you should have a reading of 2, 4, 8 ohms....you may also try to use the continuity test, same, but there will be a beep ....this basically ensures that the coil running through the speaker is still good, as one piece, otherwise it will get no good reading and this is usually from blowing the speaker or sudden high bass sounds....

Sony sa-wm500 subwoofer is crackling


If the sound is a scratchy type of sound then the voice coil has been damaged and is rubbing up against the internal magnet producing the scratching and low sound since the cone is barely moving;.

The fuse blows in the SA-WM500 whenever there is an input from the amplifier.


http://www.retrevo.com/support/Sony-SA-WM500-Subwoofers-manual/id/752ag404/t/2/


The fuse blowing is a symptom of something seriously shorted internally. What preceded the initial problem? Smoke is bad. Fire would be soon to follow without the fuse blowing. Take it to a tech.

My Subwoofer Sony SA_WM500 was always burn the fuse therefore I had to change the STK, but now it takes off sound very low, How can I have back the high sound level? Zaruque Quimuenhe


It's no clear what you mean by "I had to change the STK", but if that means you have somehow defeated the fusing or place a larger fuse than it requires then STOP and shut it off. You might be risking a fire or more serious damage to the amp.

I would recommend you find a hands-on tech to look at it.

If you have resolved the fuse problem and now just have low subwoofer volume, you might want to track it back to the source and ITS subwoofer volume setting. There IS a volume level control on the sub, too. Turn it up.

The manual is here:

Subwoofer Line In/Out Mix-up


I had a problem with no audio and I recently found the fix. When the sub still worked and you turn it on you hear one relay click and then about 5 seconds later a second relay clicks and the audio comes on. The problem I had lies with that second relay. When you take the case apart there are 4 circuit boards. The big board with the two big blue capacitors is the main board. Well next to the two blue capacitors is a blue relay. That relay had a pin that came un-soldered from the circuit board. I re-soldered that pin and the sub works just like new. If you go here http://www.eserviceinfo.com/downloadsm/20627/sony_sawm500.html you can find a free service manual that has the wiring schematics for the amp. Hope this helps!
