I may be telling you something you already know, but a lot can be learned by
looking at the fuses when you remove them.
If the fuse body is blackened, and the inner link destroyed completely, it's
indicative of a catastrophic failure (short) and there is no point in trying
another fuse.
OTOH, if the fuse appears intact and you have to use a DVM to see if it's
open, there's a chance it's just a fatigue break.

Based on my experience with three Titan 425s over six years, I'd say you
are
being FAR too alarmist. I would only open it and start troubleshooting if
a
replacement pair of fuses blows more or less right away. It is NORMAL for
these fuses to blow every six months or so, and at unpredictable times,
and
for reasons unrelated to the power amp.
