See if you accidentally connected the HU ground to a power or illumination wire.

I tried disconnecting the cables and that didn't work what else could it be???

You have made a mistake in the wiring, you will need to rewire your connections and wake sure every wire is connected to the correct one.

I did that and everything is connected correctly to my knowledge. I didn't see anything wrong with the wiring but I rewired everything just to make sure and my fuse still blows. What else could it be??????????

well use only the yellow and the red wires to a 12v+ source and the black to a ground or to the negative of the battery... ignore illumination and all the rest if theres anything else... isolate em so it doesn't touch any ground...

if it still blows i think you might have a short inside your head unit or somewhere...

make sure you're not getting a short on the speaker wires too or if the RCA isnt touching a metal part of the car, ive seen similiar problems caused by this too

if it still blows you will have to take a look at the hu, thats very unusual for a head unit

edit: may be also good if you could wire another head unit to your car and see if this one's fuse blow

What kind of car is it?

Some older GM vehicles actually use a dark brown/black for illumination. I really think that that may be your problem.
