Recently my house experienced an electrical surge during a thunderstorm. The sub-woofer powers on, but just makes a constant thumping noise. I replaced the fuse, but it makes the same noise. I was wondering if it is blown or if this problem sounds familiar and do you think it's repairable? I figured the sub-woofer has some kind of chip in it since the other speakers won't work without the sub and it just needs to be replaced.
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.
