did my subwoofer die??

hey guys, I have a psw111, works great. recently moved. after I reconnected it to the amp, worked well like before. but recently it's been on and off. I unplugged the RCA cable, reconnected it while the music /amp was on (to test out the base level - i didn't know what i was doing). then it just stopped working. I was able to wiggle the cable a bit to get it to work for a while and now it is dead again.

the light turns on but no sound is coming out of the woofer.

what is wrong? is it just the cable is dead or something wrong is w/ the sub woofer?

If you have another set of RCA cables, give them a try. It's possible that it's dead, but bad cables are just as likely, especially if wiggling the cable would get it working. If you killed the sub, you might smell some burning.

Nope. No burning smell. How can someone kill the sub?

Would unplugging the cable while music is playing kill the sub?

It wouldn't be good for it - plugging/unplugging while an amplifier is on introduces a signal to the sub (try doing it with a speaker, while the amp is turned low - you will hear something, whether there is music playing or not) - add a music signal to that, and you are increasing the amplitude of what the subwoofer is suddenly dealing with. BUT, I wouldn't normally expect that to kill a sub. Killing a sub usually means wrecking the voice coil with too much current, or damaging the speaker itself, ie the foam surround.

change the cable; test. change the audio source; test. if it's neither of those, then you probably broke the rca connector off the pcb. unfortunate, but probably pretty easily fixable if you can solder. you'll probably pay a bit to have it fixed at an electronics store.

Before throwing it out, I would follow ChubChub's advice. Open it up and see if the RCA connector is still connected. It might be a loose connection on the PCB board. BTW make sure you unplug the Sub before you open it up.

Given the potential failure mode that this guy is describing, it might be that the RCA connector is weak, and many of these "amp failues" are just a bad connector.

You might want to consider buying better quality cables, if that really was the cause. Not $$$$ cables, but decent cables.
