Sub/Amp Circuit Fuse?

[JBird_Cobra]

Quick question for someone who knows what they're looking at. I have a small sub/amp in my DD and blew something when I hooked it up a few days ago. The inline fuse in the engine bay is intact and the fuse on the back of the sub box is fine as well. I'm assuming there's a fuse on the board inside the sub as shown below... anyone have any insight on what it looks like before I take a few guesses? Thanks.

I see no fuses on that PSB.

Crap that's what I thought... I have no idea where my issue is then. Time for more investigation.

There aren't internal fuses on any amp I've seen. If they have any, they're external.

Yeah I've got the 20A in the engine bay and 20A on the back of the box. This was some MTX special with the 'amp' inside the box. All I did was plug in the RCA cables and heard a boom... the 'status' light is not lit anymore so I assume something blew somewhere...
