While I was rewiring the stereo stuff, I noticed that the subwoofer wasn't playing.. Further inspection suggested that either the fuse was blown, or the powered amp was hosed. This picture was supposed to help me read what was said under the fuse (the triangle). It did not. [The fuse turned out to be fine (unfortunate) so I've got to take the thing in and get the amp replaced. It will probably cost me one of my internal organs.]
