I have a klipsch subwoofer that turns on and doesn't send audio I have no idea what the problem could be I had it in use until this morning and suddenly it stopped playing what could it be? subwoofer amp? By the way, I have not opened the subwoofer, I only have it in my living room, I tried several things, I changed cables, etc. And I'm not from Mexico, can you give me an idea?
