No sounds from speakers, only the sub-woofer

The sub should generally have its own power supply, is it plugged in ???

try pacparts.com.

sounds like they are picking up interference. make sure they are grounded well.

design u r aucostics properly

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.

Did you try making sure the subwoofer is turned on under the set up menu on the Sony Receiver?

Press Set Up, Press the left or right button above the scroll wheel until you get to SW. It should say SW: ON or SW: OFF. If it says SW: OFF, use the Scroll wheel to scroll right until it says SW: ON. Also, make sure you aren't in 2CH mode, try A.F.D or surround sound.

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

By changing your battery you reset the DVD player and locked it out. It now wants the code to restart. Here is a link to the owners manual: http://esupport.sony.com/perl/model-documents.pl?mdl=XAV7W I hope this helps, Shuttle83
