Car Audio speakers hum?

Question

Okay nothing in my trunk is bolted down.I was riding today and when i made a corner I'm guessing my faredcap{Sp?} touched my sub amp{which is metal}.The subs started pounding out bass even when I turned the sound all the way down.I turned the radio off and now when it's back on the bass isn't pounding but it goes from hearing vibration to feeling vibration back to hearing vibration.If I turn the radio off it stops so I know it's the speakers{or atleast the system itself}They don't sound blown and if you turn it up like I like it you can't hear.But with the wife the music can't be loud and this sound annoys me bad enough I just turn it off.Everything looks okay and sounds just as good loud.Also the wife said it smelled like birthday candles after you blow them out right after it happened.I didn't notice anything burned or melted wires.Any advice or suggestions?

My first suggestion would be to go over all of the wiring. Make sure that everything is in place. 

Next, I'd at least mount the cap and the amp. Just to make sure that this can't happen again.

Well the reason they are humming is cause they don't know the words.

You probably blew the subs or the amp but this should have been avoided by the fuses within the amp.  The best thing you can do is go through a diagnostic.  Unhook the sub and leave one on, if you only have one, find someone with one you can test with and see if the issue is with your sub (the sound will stop) or the amp (the sound is still there)

Disconnect the battery negative and check all the wiring.  oh...and when you replace everything fix it down to prevent things sliding about and shorting in future.
