SOURCE: Yamaha YST-SW320 subwoofer won't play sound

I too have amplifier and speakers thatI rent for parties, and sometimes when I connect them they don't work and I battle with them for hours before I find the out that its just a little thing that happened, like speaker wire might have cut inside, or the wire conneted for the CD to Amplifier is bad and son on.

But I will advice that you test your amplifier and woofer, with another equipment independently to be sure if they still working well or not. As this will help you to know what to do next.

May somthing happened to one of them the last time you used it and you did not notice, and it might just need some servicing.

Best wishes

SOURCE: No sound from my Yamaha

Feed it with an RCA cable any other audio device you may have (CD, TV, MP3 player, PC) to prove it can or can not woof. It will respond to any audio, not just LFE or subwoofer audio.

I believe that the chips are easily reused, but only once per printer. There are two options:

I get mine from Ebay. A 5 pack (2 black) of 100 xl runs around $25 and shipping's free. I've gotten a few and haven't had much of a problem. Once in a while they'll be a little finicky getting started but I've never had a problem with the printer accepting it.

How do I connect the YST-SW45 sub to a different system

It's a standard non-proprietary standalone self-powered sub that accepts any input one could want. Your unnamed electronics will be the determining factor. Manuals spell it all out.
