amp suddenly stopped working

[kayan zidan]

I have a lightning audio la-2000md and i am running this setup with another mosfet amplifier on a 240 amp power supply. I just turned on my amplifier and it is lighting up and everything but I am not getting sound out of that lightning audio amplifier for some reason it worked fine yesterday
i am sure that the subb is working i used it on the other amp and it worked fine so and i know i am getting an audio signal to the amp but i am not getting out of the amp any signal
thanks for the help

Sometimes amps go bad. Check your wiring again. May have to get another amp. Good luck.
