    Why does speaker wire touching metal create gnarly screeching?

    I installed some component speakers, but at the moment the speaker wire coming out of my xover for my tweeters isn't connected to the tweeters and is just hanging around. I noticed today that a couple times it bumped into my door (no door panel all metal) and all the speakers created an extreme piercing screech. What exactly causes this and what is happening when that occurs. Something with grounding i would imagine.

    Could I have damaged my speakers/amp? Just wondering thanks

    Prolly picking up engine noise through grounding older cars had this problem since the speakers grounded to the car rather than the amp

    Still no insight into what causes this? I'm looking for science here people. Mind going into detail on what this does to the amp? I already reattached the tweeters and everything sounds just fine

    We could explain but honestly I don't think you'd understand.

    I realize that my outputs are contacting grounds, but didn't see the connection between that and make the rest of my channels scream.

    dude you are grounding out your amp,you keep doing that you will blow that amp,your amp chassis is grounded,your speaker outputs are AC voltage and AC current,and you are letting that AC power touch a DC negative ground,so...........what do you think is going to happen???????????/
