As I was installing an old led the positive wire came loose and come out of its connector. How exactly do I fix this I tried just pushing it back in but it didn't work. Also hooked a wire from my sub to my toggle switch where my leds are wired to see if it would work and now sub don't work. Possible blow fuse on amp? Thanks in advance

 

The wire came out of the light itself? if so you'll most likely have to solder it back on, and what do you mean you hooked a wire from the sub, the sub has to have a complete circuit to function

 

fixed the amp, but still lost on the led, i keep trying to put the wire back in but still not getting any power at all

 

Pics of what you're talking about?

If it's one of those little 25 cent strips just buy a new one?

 

Pics would help for sure. Soldering the wire back on would be your best bet. It may not even be worth fixing because the price have come down on them so much you can probably replace it cheap.
