Radio "thumping" Quit
I have a 1997 Ford Expedition.
The other day I noticed a loud "thumping" noise coming from the truck. The key was out of the ignition, and the noise continued with a little feedback. We pulled the fuse, and the noise continued for a few hours. Eventually the "thumping" ended, but in the same time, my radio quit working.
I have the factory installed Premium sound in the dash, with the 6-CD changer in the console.
Any thoughts on "How to identify where the problem is" and "How to fix the problem"?
I appreciate any thoughts...

IN my honest opinion, the only time I have heard a rythmic thumping sound is when the battery is about to go out and the
amplifier is still on (no signal from head unit) radio off....
the amp will make the speakers move....making it sound like
a soft thump....
Get your amp checked out....perhaps it is staying in the on position until the power bleeds out.....causing the thumping...
When I first heard it I thought there was a Poltergeist in my friend's truck.
Also check out the turn on lead for the amp and make sure the radio shuts it off completely upon turning off.
