The head unit comes on. Receives radio stations and everything as far as i can tell there is nothing wrong with it. But there is zero sound going to the speakers. Can i replace the amp? Is there a better solution?

 

I'm on my third amp. After the first replacement failed I opened it up and some of the capacitors had lost their jell. So far I've just bought used working ones from car-part.com, but I suspect the time will come where we will need to turn to electronics refurbishment shops to have the capacitors replaced.
