Hey, I have some old PolkAudio speakers that came with a Hewlett Packard PC. I don't know which ones they are but I've been trying to hook up other speakers to those and I did everything correctly, but I had put the connection through the Headphone hole to make the other speakers work. Last night I was testing it and it was fine, but today I turned the volume up on them and they shut off out of no where. I checked all the plugs for electricity, but still nothing. I'm guessing I blew the speakers, did I? I wouldn't think they would just turn off, just have the sound be horrible. Someone help me out, I'll post a picture of the speakers if needed.
