Amplifier is Overloading.
Suspect the speakers are not connected correctly
Is the side of the wire with the embedded white stripe + or -?

Thanks.
Brm

Usually positive.

Thanks.
It still is Overloading even with the proper connections.

Disconnect a speaker at a time and see if it still overloads?

Don't keep the volume at 11.

Change the battery in your hearing aid.

You don't say whether this is a recent problem with long-owned kit or due to new speakers or amp in your set-up. Some amps* do need specific speaker wire, not the cheap thin cable commonly used. It's too technical for my simple mind but I believe it has something to do with impedance.

There's plenty out there to research ... I've just scanned this: https://www.the-home-cinema-guide.com/speaker-impedance-matching.html and this may be the root of your problem, i.e. your amp is having to work too hard to drive your speakers.

* my hi-fi amp manual specifies its branded speaker cable (the cheaper version costs a lot!) but other branded products can be used albeit with a different sound.

Good luck.

New problem.
Yesterday I thought I had fixed the problem.
No cutoffs from yesterday afternoon till 10 am today.
Then it overloaded again.
I currently have three speakers attached and all is well.
Hopefully the problem will go away.
Ben

Ps. This has happened in the past but never lasted more than a few minutes.

No more than two speakers are in use at any time


Thanks everyone.

Where do I start?

The plus or minus part of the wire is not a problem, so long as the plus/minus out of the amp matches the plus/minus input of the speaker. If something does not match you will have phasing issues more than anything- where the sound image is shifted to one side or another.
Make sure you have some decent stranded speaker wire. Go with Monster brand, or something of comparable thickness and weight.

Is this a simple amplifier (stereo in/stereo out), or a tuner/amp with many ins and maybe a surround or various zones out?

For a simple amplifier you want to leave it at one speaker on each L/R channel (there are important electrical theory reasons).

Also, the amplifier should be rated for a higher wattage output than the speakers for important sound quality reasons (but beware driving the amp too loud and blowing the speakers).


But it's hard to tell anything like this because I can't tell what your set-up is and what you hear as 'overloading'.
Could be a blown speaker that acts up only at certain frequencies, or a chip in the amp acting up with increasing frequency.

Is your amp a Yamaha?

It is nearly impossible to say since I know nothing about your amp or speaker, but the number one cause for overloading an amp are wrong impedance levels on your speakers. Is this an old setup where the problem has just recently arisen, or a new setup?

Decades old.
Problem is gone for now.
Can you explain more about the switches on back of speakers.

Mine have settings for the tweeter midrange.
Thanks

Actually I am one of the few people here who aren't deaf or suffering from tinnitus!

That's good - I'll share my tinnitus with you.

Yes, LC wouldve had a jim phelps number on that one in fave posts.

Not even remotely funny.

And I thought this was one of my many jokes that fell on... deaf ears. Bob made a Spinal Tap-ish joke so I figured mine was safe and not considered 'negative input.' wink

Again, since I don't know exactly the speakers we're talking about here, I can only guess. There are speakers which have switches (or bridges) on the back that allow for more (or less) pronounced hights or midranges. The "correct" setting in these cases is usually whatever works for you (and particularly your room), it should not affect the amplifier. An amplifier may for example overload if a speaker's impedance is too low. Say, if your speaker's have an impedance of 4 Ohm, but your amplifier has a minimum limit of 8 Ohm, then you go into troubled waters. (The other way around is not that bad.)
Today's speakers AND amps tend to be made for an operating range between 4 and 8 Ohm (both speakers and amps), so many amps fit with many speakers these days, but there are always exceptions.
