Subwoofer died?

[Tristicus]

Yesterday, my sub was working fine (as far as I know), as it was the day before that. I wake up this morning, turn everything on, and the first thing I notice is that I'm not getting much bass (it sounds hollow). So I go check, and apparently, my sub is powered on but not doing anything. All connections are fine, I restarted my PC, I even checked another source, and nothing. While my speakers have okay bass themselves, it was noticeable that the sub wasn't working. When I put my ear up to it, I don't even hear buzzing really.

What could be wrong? A fuse maybe? The light powers on green like normal, I just hear nothing. If it is a fuse, will it be simple enough for me to open it up and replace it myself? The sub is an AIWA TS-W60 Powered Subwoofer. Receiver is a Scott A1610 if that makes a difference.


EDIT: Well I feel stupid, I unplugged it and plugged it in and it works again. Herp derp. Could this be a sign of it dying though, or just normal?

Is it always left on? a power spike can sometime trip a fault protection and make it go into protection mode until the power is cycled again and it knows there is no power issues anymore, happend to my old HTIB system a few times a year.

Could be a resettable fuse that overheated for some reason. Unless it happens often I wouldn't worry about it.

I turn it off at nights, but it could have been a power spike. That makes sense.
