Here's the deal. Everything powers up, but when i raise the volume, the sub start producing a cracking sound and if a raise the volume real hi the sub just died. Also one of my rear speakers doesn't work.

Re: Subwoofer crakling sound when playing anything.
Hi, this is a particular problem for this speakers, and subwofer, it is a resistor inside the sub, you have to fix it in a repair shop, or ...sadly, change for another model of Creative Speakers, for example one good one is the 7800 Spk. good ones.
but like I say is a problem that creative labs is aware too.

The speaker is designed for computer and not designed for playing at loud volume. Sound like you have blown a fuse, check the fuse on the back of the subwoofer and replace it with the same rating fuse. The speaker are only rated at 2 to 20 watts max, with the sub at full volume it did not have the power required to produce the sound thus blowing a fuse or burned out. The bass is the most power hungry of all the frequency, if you are using 5 watts and the note spikes to double your amp has to have 50 watts of power to produce the sound. Hopefully it was only the fuse, good luck.
You can prove the sub pre-output works by running an RCA cable from it to the input of a tape deck, TV or any other device that accepts Line In and will either display it or play it. Test it on VERY LOW volume at the receiving device.
Dive back into the setup and make sure you have the sub defined (page 19). Run setup. It should work.
If not, tune FM, run an RCA cable from either Record Out channel to the sub's input; or connect a CD directly to the sub. Gradually raise the volume with something bass-rich playing. That ought to wake it up. If not, the sub is dead.
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!
The best thing to do is to contact the manufacturers. From this i understood that your speaker system is new. You surely have the manufacturer's guarantee. So its better to contact them than to get it repaired or replaced for free. Sir please do not try to open the sub as it will void the guarantee policy.
Hope your subs come into play as soon as possible....... All the best...
Make sure the subwoofer is set to low frequency, make sure subwoofer and bass are enabled on the headdeck. Make sure the gain is turned up on the amp, make sure the rcas haven't come out of the back of the head deck.
u might have to turned your amp so u can play both subs your amp might be to small to run both subs at the same time an u gotta play around with the settings on your cd player so when u blasted your subs it has that nice bass to it not that poping sound.
i had the same problem when i tried to adjust speaker output levels, distance and equalizer manually without using audessy setup..so i reset everything to factory setting (0s)..and then ran audessy setup..reduce volume on your subwoofer to slightly above minimum(behind the subwoofer) before running the setup..once audessy setup is completed successfully..i started changing setup manually..changed speaker config for front speaker to small (it is set as large by audessy setup), this should automatically adjust center and other speaker configuration (if not make sure to set them to small as well), then set the cross over frequency to 120..increase the volume on your subwoofer and now you should hear it fire..if this does not help..try playing some rock music with all channel streo mode..if your subwoofer does not fire even for this..then take the system back for exchange..
