Cam, I don't know how to test for a blown fuse besides taking the unit apart. Nor do I know how it happens. . .

I had a fuse go out on one of my amps. Rather than no sound, I got garbled static out of one tweeter.

Have one of your friends come over with a screwdriver so you guys can check the innards. The hard part may not be diagnosing the bad fuse, but finding a replacement one. Find out what you need from Emotiva.
