i have a jbl amp, and i recently had a friends box hooked up to it to make sure his subs worked, which they did..........then he disconnected the wires and there was a spark, and now my amp is acting really weird. its got a red light which signifies a problem, and a green light which means its working fine.......the red light is on, but the green light comes on dimly then goes all the way on and my subs work for about 1 second, then the green goes away again. any ideas on what happened??

 

if you have your manual it shows troubleshoting techniques on the amp? which amp is it?

 

its the p180.2.............i downloaded the manual for it, and what its doing is not in the manual, so i don't really know whats going on with it.

 

Did you check the fuses on the amp and on the power wire. I would say pull them out and look at it closely.

 

you tripped the overload switch.. usually it resets itself after you turn off the power for a few minutes.. if not..your still tripping it..check your screws that screw down the speaker wires.. i bet your have the screws touching one of the other channels your grounding it out..make sure nothing touches each other.. the spark i wouldn't worry about if you have the right fuses it would short out before any damage...

 

thats what the problem was, the ends of two of the speaker wires were just touching......i moved them around a bit, no longer touching.........got bass again, thanks
