I was wondering if anyone had a consensus on what the effects of putting a breaker in series with the output of my chipamp. My amp can do around 50W/channel and my speakers handle like 30W max. I'm afraid one of my dumbass relatives are going to come over and blow them out or something...
Anyone ever use breakers? I was looking at polyswitches but I didn't like their characteristics in term of hold current and trip current. Fuses are nice, but...replacing them would be annoying.
Ideas?

Just reduce the output of the chipamp to 30 watts by changing its supply or reduce the gain.
You can also put a resistor attenuator in the signal path.

I have been using 70 W speakers on a 150 W amp without any problems the last decennium or so. Just don't turn up the volume too much. Besides, more speakers are blown up by underpowered amps trying to work too hard (clipping) than the other way around.
actually, don't worry about it. you would blow the speaker up with distortion before you could actually get to the over powered wattage state.
you should have 3db headroom on your amp compared to the speakers. 50W is pretty close, (60 w in your case )
circuit breakers are too slow.
but if you are that paranoid:
a 12 V .97 A lamp in series with the speaker will limit the overs. they are used to protect 30 W tweeters in P.A. Speakers

I would look at an attenuator on the inside of the amplifier.
The attenuator could be bypassed with a 0.1" shorting plug. Just like the plugs on the back of IDE drives and on Motherboards.
Set the total gain so that no output even with the volume control set to maximum, will clip on it's way through the power amp.
This is a little bit different from the "normal" gain setting where the quietest source should only just be able to clip the power amplifier.
