LSI25 amp problem

So yesterday I picked up a pair of Polk LSI25 speakers at my local goodwill, and when I fired them up this morning, the sub in the right speaker wasn’t working. I decided to pull the amp board and take a look inside. The fuse was blown so I replaced it and plugged it in, and immediately one of the things that are the actual amps (can’t remember what they are called all of the sudden, it is one of the four pieces on the side of what I believe is a heat sink) began smoking. I don’t know if the amp powered on when I did that because I was paying to much attention the smoke, but does anyone know what could be the problem and how I could fix it?

Thanks,
Micah

  • While I was here I thought I would ask, I currently have a Yamaha amplifier that only is able to go down to 6 ohms, will this be a big problem that I have to fix ASAP or something that can wait?
