Old speakers and new receiver/amp question

I've got a set of old '70's speakers that suit me fine. Right now they're
being driven by a late '70s Kenwood kr-2600. I don't know what its output
is.

If I use a newer receiver/amp with, say, 100 watts output, will the old
speakers get wrecked?

Not unless you turn it up so loud they are obviously overloaded.

Richard Crowley...

Only if you turn up the volume enough to damage them
(and/or your ears).

If I buy a new car with double the horsepower, will I
get a speeding ticket? Only if I choose to use the extra
power to go too fast.

Doug Kanter...

Too many factors to answer the question accurately. If you listen extremely
loud, and your receiver doesn't have enough reserve power, any speaker, new
or old will be damaged. You can only tell by listening. Specs are just a
guideline.

Alex Rodriguez...

Shouldn't be a problem. Just remember to use your ears when adjusting the
volume. If you slowly turn up the volume and the speakers start to distort,
that is your que to back off. This works with both modern and old speakers.

AZ Nomad...

Can't you manage not having the amp's volume at 10 all the time?
