One speaker making a popping sound

that 4 pops sound is a built in feature of the new system .

Try put a ground line from any metal of your stuff to the any metal direct to the ground. these eliminate noise of the speaker.

Check for any external shorting of the speaker wires. Check for kinks or cuts in the cable that feeds the speakers. Also check the posts or socket at the back of the speakers for damage or wiring shorting out. Proactive IT Support PC Repairs Laptop Repairs Custom Built PC Leading IT...

no its not to new its starting to have problems.JVCs arent known to llast maybe 2 years get a good pioneer youll be happier.

hook your front speaker wires up to the A side and on the front of it make sure only the A speakers are playing but leave the rear speakers plugged into the B side then hit the listen mode button and you should be rocking

Had the same problem on the same machine 15 or so years ago...took it to the Bose factory shop in Framingham (or real close )Massachusetts, and they fixed it in 20 minutes...cost around $50...at the time they said it was a real common problem, and an easy fix.

Hi when you turn on check all your speakers work check connections make sure the wire has no stray strands touching the fault could be in the sub unit this is possible / or your speakers one or more could have gone short circuit due to exessive volume thats if you play loud. Had a party lately .Just joking .Regards kirk

disconnect the woofer and connect a different speaker see if other speaker makes the same pop if it don't then the woofer cone is defected if you have high watts and using stereo on high volume you can damage speakers.

The problem is a burned transistor inside the subwoofer. It depends of country's transistor manufacturer. It is supposed to be of a low quality. It's not important for the scope. Mine is knocked down for a year. I saved the electronic schematic diagram and the transistor specs, but lost. I confirmed the cause opening the subwoofer and examine the board. The indicated transistor surrounded area is burned indeed. If anyone find the article in web, please, post here. 

you should check the outline ctrl..for a mic...it could produce a noise...if you have your speakers connected to pc...check the position of the plugs and the volumen of mic put in down...
