I just recently hooked it up, it was playing great then I moved it just a little tiny bit so I could screw it down. The ground wire popped out, I turned off the truck and put the wire back in and secured it tight. Ever since then my protection light has been on and hasn't shut off. It wont play because of the protection light. If i take the speaker wire out the light still stays on, any ideas?

 

what amp is it?

 

Brand new Power Acoustik 620. I was told maybe my ground could have came loose or moved.

 

check the fuses on the amp. one might have blown when the ground came out

 

Both were good. I sanded a new area and put the ground in and its great. Thanks for the help guys.

 

you know im having almost the same problem right now too
was playing fine then shut off,fuses were blow so i changed them now the amp is in protection mode and i redid my ground also and still wouldn't work

 

Something simular happened to mine, but not only did it blow the amp fuses, it blew then power wire fuse also.... if you havent, check that one to
