If it's happening only in one speaker, then the speaker is almost certainly damaged.

I have Mercury 2.1 white speaker.It works fine for half an hour but after that the woofer's sound stops-start frequently at highest bass but when I reduce the bass It works normally with no distortion.

If highest bass means you are boosting the bass for effect then it may be some form of speaker protection cutting in.
The most likely is a Polyswitch, which increases in resistance as it heats up when too much current is going to the speakers. The sound resumes when it has cooled down.

A common reason for 'distortion' with all bass amps can be either that the screws holding the speaker unit to the cabinet have worked loose or that there has been a build up of dust particles in the corrugations around the edge of the speaker cone, which rattle especially on the lower notes.
The solution is simple - remove the front grille and check the screws are tight. Use a vacuum cleaner to remove dust from the rim of the speaker cone.

I have Ibanez gsr200 bass guitar , yesterday and today I noticed that my bass's voice is irregular , please help me how to solve it , It's a new bass , Thanks

No question what to do... take it in under warranty since it is new !!!

You may find that there is a problem with your amp... the seller should be able to test the guitar and demonstrate normal sound for you.

Many users have TOO small of an amp and the distortions make it appear that the guitar is bad... I suspect you will want at least a 12 inch speaker and preferably a 15 inch for your bass.

When low frequency signals drive a speaker too hard it drives the voicecoil out of the linear range and the sound will be irregular..

What duz level adjustment do


The level control controls the input level coming from your head unit (receiver) to the amp.

Your Sony users manual is a little vague on how to best adjust the level and other controls.

Here is one method that some installers use and works well with most amps.

Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.

Hope this helps.

Center Speaker Audio Very Distorted

Love your screen name.

You didn't say what, if anything, preceded the appearance of the problem. There might be a clue.

Can you describe the distortion? Is it excessively bassy? If so, is it happening on all sources?

I'm assuming this is a modern digital receiver that is capable of many soundfield simulations as well as native Dolby Digital, DTS, multi-channel. If so we can use a stereo source and through simulation redirect some of it to the center speaker.

Using one of your receiver's many multi-channel simulation modes, put in a CD or tune an FM station and use it to diagnose the problem during later steps.

If it's only a single source and that source uses individual analog channel RCA cables, swap in another one or temporarily move the Center Channel feed to one of the other channels to see if it's before the receiver (in the source).or inside the receiver.

For multiple sources:

Is your Center speaker defined properly as Large or Small in the receiver's setup menu?The size refers mostly to the bass-handling capacities of all your speakers rather than their physical size. Speakers designated as 'Small' will not be sent much in the way of bass because they can't handle it well. The LFE/subwoofer channel(s) will get all the bass that was intended for them instead.

If you have a Small speaker improperly defined as Large it may be getting bass that it can't handle and that might sound like distortion. Having a Large speaker defiend as Small would result in less bass than expected but otherwise 'clean' sound.

Check the speaker setup in the menu for excessive volume level relative to the others. There is usually a calibration procedure the receiver will use to help you adjust the subjective voume of each speaker using white noise or tones.

Hope this helps.

Amp went into protect, but front speakers sound distorted too

If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.

Distorted Bass

Check the specs on the required ohms for the speakers. If it calls for 8 ohms and your speaker is 4, then you are pulling twice the normal current and this has blown an output transistor.
