I'm very impressed. Given eight ohm speakers the fuse will open with P =
I^2R or .5x.5x8 = two watts going into the speaker for long enough to
heat up the fuse and cause it to open. I'm assuming, however, that the
fuse operates properly with AC. You should study the datasheet for this
part to confirm this. If you hit a snag, holler and I'll ask a guy who
knows a lot about this type of device. But well done you!

I have some NP capacitors in the closet wired into the wires going to
my kitchen speakers. It occurred to me that I don't need those if I
switch my receiver back to crossing over. It was the tweeters I was
blowing up anyways. I soldered these in this time for the tweeters
but plan to be careful. I had .75 amp ones in before.
