Help with location of fuse for radio

[mishaaakap]

So I was driving along jamming to a song when I went to turn my radio down. Doing so the deck went completely black, no response at all. I'm thinking I blew a fuse but I have no idea which one. When I bought the car it had no manual so thats a bust. Does anyone know the fuse location? I would just pull the fuse box and take a look but I have an Injen CAI installed which blocks access to the box.

Thanks in advance guys
