You are right about the scratching sound meaning the speaker is blown. The other one by it not playing it could mean the voice coils in it are blown or burnt.The safest way to check the speaker is to connect it to a standard 9
volt battery and listen for a popping noise when you make the connection
and look the see if the cone stands up as long as the connection is
made n returns to normal and no noises when disconnected from the 9 volt
battery. To test this while the sub is plugged in to the amp but out of the box move the cone as far in and as far out as it will go. If it comes on while u hold it on either one of these positions but when released it goes back to not playing then the coils in it are blown or burnt and is no longer any good. As for selling the box its on you, aim anywhere from 2/3 to 1/2 the price you paid for it minus the speakers.
The LED should be red. If you are not getting power to the sub, make sure the speakers are connected properly to the amp. Also make sure that the gain control is turned up. If it is all the way down, you will not hear anything from the sub(s). If none of that works, it is possible that you have a blown sub. If you smell a burnt smell near the speaker magnet, there is damage to the voice coil in the sub.
Hmmm, let me see here. Did you mean to say you have TWO subs connected to this amp? A single sub can only be wired in series with the amp. Even if you have a capacitor wires in parallel, the capacitor is not a load, but a souce equivilant, and therefore can be merged with the amp as a single source when put on paper.
When they say a sub or amp is so many watts rms, that means that the device can function safely, without worry of failure. THERE IS NO LEGAL METHOD FOR DETERMINING THIS NUMBER AND NO REGULATIONS ON VARIANCES. Having said that, if an amp is 500w rms, it could very well push double that for long enough to blow your speaker. It all depends on how much power went through that speaker. So since you have a 4 ohm speaker, not two, and it would actually act like a two ohm speaker if you put another one in parallel because 4||4=2ohms equivilant. never never never, turn the bass all the way up if your gonna beat loud. Low frequencies draw lots of power and can damage your system.
you can tell if your speaker is blown by turning the volume to a medium listening level and placing your hand on the cone. you will hear a crackling sound if it is blown
this is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....
first take the amp out. smell the amp youll smell a fried or not then test the sub even on home stereo i doubt its blown these set up are 250w max. i bet then you will realize that it is tmhe servo technology easy fix is to get a small external amp then you wont have another problem
it sounds like u blew them or the voice coils could be messed up here is one way to check take the woofer out of the box and look at the coils it should be ornge and then smell it if it smells like fire it might be going bad thats the reson it is frezzing like that let me no what happens and please rate me
i had the same problem, apperantly creative made an error making the hardware for the subwoofer, and put in an mos-fet with to little resistance, i called creative and gave them the serial number behind the subwoofer and they sent me a new one that hasnt acted up yet.
UNPLUG THE GREEN WIRE FROM THE COMPUTER AND PLUG IT INTO A CD PLAYER IF IT WORKS BETTER ON A CD PLAYER THAN THE COMPUTER IT SELF THERE MAYBE A PROBLEM WITH THE SOUND CARD AND ALSO TRY THESE STEPS I AM GOING TO GIVE YOU I AM SURE ONE OF THEM WILL WORK.
1. Please ensure that the all the connections between the satellite speakers and the subwoofer are firmly connected. 2. Next, please connect the green colored 3.5mm audio jack to another audio device such as an iPod or an MP3 player. 3. Ensure that the SoundTouch
remote control is firmly connected to the back of the subwoofer. 4.
Connect the power cord from the subwoofer and connect it to another
single power outlet in your house. If you have an automated voltage
regulator (AVR), please connect the power cord through the AVR instead
of connecting it directly to a power outlet in your house. 5. Power up the speaker system and check whether the power button on the SoundTouch remote control will light up. 6.
Turn on the Matrix Mode ON. This option is on the SoundTouch remote
control. This is to ensure all speakers from the speaker system will
produce audio that will be played from the audio device. 7. Play audio from the audio device. Check and see whether the all the speakers will produce audio being played from the audio
