I recently got a pdf copy of the owners manual for my resurrected Bose 601s.In the manual it says that if you wanted to you could put a fuse in series w/ the + speaker terminal.I have seen Polks where there are fuses on the outside
but was not sure if they were spares or the working fuses.So the ? is, I know it can't hurt but do you guys do this as a practice and if besides Polk name the brand that has in line fuses ready to go.
