It's in the fusebox, which has a map on the inside of the cover.

You read your owner's manual. The location of the fuse boxes are listed in there.

There could be two different fuses for the stereo. In fancier systems, there can be two different fuses - A smaller fuse in the driver's side under-dash fuse box, & a larger fuse in the under-hood power distribution box.
