So i installed my sub about a year ago, just recently it stopped working. After driving for a little while it turns on?, but once i turn the car off and turn it back on again the sub continues to stay off?.

Anyone have any idea what the problem could be?

 

sounds more like an amp problem, check your grounds

 

hahah +1... I have the same issue... I ground my LowPass filter near the stock amp and that connect is hella loose... comes on n off... i should really do my trunk

 

my friend had the same problem, his amp was over heating, and the connections were loose. so i think its time to upgrade to a new or nicer amp.

I'd check the connections first, more specifically the ground.
