Can using home theatre speakers on a different amplifier cause any damage?
Question: About 2 years ago I bought a gorgeous SONY home theatre system, sadly the amplifier was damaged, and I stored away the speakers.
Now a friend of mine is willing to sell me his newer, but very similar model sony amplifier (different model) which has the same connection ports as my old one.
Now note that the speakers on his new newer system are relatively more powerful than my 2 year old speakers. If I connect my old speakers to his amplifier, could there be a risk of either of them getting damaged due to different level of sound wattage, etc.?
Answers: I doubt there will be any risk at normal volume levels (LOUD but not LOUD!!!!!!) Digital sources add very little harmonic distortion to audio signals, which means there is little risk to your speakers.
Check in the manual for impedance ratings on the receiver and the speakers. This is listed with the wattage ratings. On the receiver there will be a rating of, for example, 100 watts per channel @ 8 ohms. The impedence is the ohms measurement.
Then check what the impedence is on the speakers.
Here's where it gets a little tricky. An amp (or receiver) sends out an audio signal at varying ohm levels depending on the sound it is amplifying. Wattage changes at these varying levels and increases the lower the ohm rating. That means that an impedance of 100w at 8 ohms means that the amp could put out peak signals (such as an explosion in a movie) of 400+ watts at 2 ohms impedance. Every amp/receiver does this. But differnt brands of amp/receivers use different ohm ratings to give their specifications (eg Marantz may rate their wattage at 8 ohms and Pioneer might rate their wattage at 2 ohms).
In short, if your speakers are rated for 75 watts at 8 ohms they should easily handle an amplifier that is rated at 150 watts per channel at 8 ohms, 300 watts per channel at 4 ohms and 500+ watts per channel at 2 ohms, as long as you don't regularly drive the speakers for long periods at greater than 1/2 max volume.
Not really because I have them to but my ears arent busting
I asked a similar question at Best Buy and was told that the only 'problem' with using 'different speakers' was the 'connection' problem ... so if your two year old speakers will connect with the new 'amplifier' you should try it ... with the 'worst that can happen' being that you don't get 'sound' that is 'quite as good' because your speakers are a bit weaker.
Two things to look at before conecting the speakers. Are they able to handle the output from the new amp, and are tehy the right impedance. You don't want to connect a 100W speaker to an output that can generate 200W as this will damage your speakers pretty quickly if you turn the volume up too much. Also if the new amp needs 8 Ohm speakers and you put 4 Ohm speakers to it you'll damage the amp.
As they are both Sony you should be OK but just check first.
Yes, you can use them, up to the power level they are designeded to and if they are same input impedance ( omega ) .
If the new station power is bigger, watch your level volume .
What are the two sets (old- station & speakers, new- station ) power ?
ok: according to Sound Equiptments orAudios well see
it's dangerous where if the noise level reaches more than normal
33.3mhz ! any way did yourself read lable before using Amphire?

You have nothing to worry about.
bassmonkey1 has it backward, you are much more likely to damage speakers under powering them, than over powering them.
Sony surround sound amplifiers have extremely high THD ratings, which is not a good thing. It means they have a lot of distortion. Distortion puts your speakers at risk of being damaged.
To properly match an amplifier's wattage to a speaker's wattage, the amplifier's wattage output should be rated 1.5 to 2 times that of the speaker's wattage.
So if you have a speaker rated @ 100 watts RMS 8 ohms, the amplifier should ideally be rated at least 150 watts RMS @ 20Hz - 20KHz 8 ohms per channel.

DJs & live bands push their speakers very hard & QSC is one of the most trusted brands of amplifiers in professional audio. They would not be recommending amplifiers rated higher than speakers, if amplifiers were supposed to rated lower than speakers.
You shouldn't have anything to worry about if you just use some common sense.
Tell your friend that you need to test out the amp before you buy it, to make sure that the amp and your speakers will work well together (If he's a true friend, he'll go along with you on this.)
Hook up the speakers, and play some of your favorite music, starting with the volume at modest levels, and gradually cranking it up, listening for distorted sound ( fuzzy sound or a lack of clarity) as you do this. Any halfway decent speakers can tolerate some distortion for a little while without sustaining permanent damage--so if you start to hear any distortion, you just need to cut back the volume. At the very worst, you will hear distortion, which will be your speakers telling you that they are not a good match with this amp.
But I think that the odds are very high that you will be able to play your music at a volume plenty loud enough to please you, without any distortion and without any real risk of damaging anything (except, perhaps, your ear drums).
