faulty fuse, ohm load too low(sub at a lower ohm than the amp can support), bad ground, over powering the amp(how did you set the gain on the amp? or did you have it installed at a shop?)

No air flow to cool it. Where was it mounted.
One of the outputs shorted.

You cant gauge how much power u are sending by how far the gain knob is set. The only way to know is to break out a calculator, a digital multi-meter and a test tone.

The amp should not have caught on fire no matter how many watts it was pumping out or what its load was at the speakers, basic sound electrical engineering design principles prevent that. I'd guess inadequate air circulation around it like from being mounted in a confined space, an amplifier design flaw, or a component failure.

2x

How long were you listening to it before it caught fire? If not very long I'd guess a design failure.

What music were you playing? If Jimi was tearing it up on a wicked solo, I'm not sure that's covered under any electrical engineering guidelines. (Couldn't resist). Sorry about your amp.

You do have it fused correct? The fuse should have blown waaaay before a fire started. Also did it have a good ground? Any loose connection will cause a choke point for the flow of power and choke points get hot.
