How do you select speakers with respect to the impedance of the amplifier?
Amplifiers are rated to operate within a range of impedances. Typically, a domestic amplifier will drive a minimum impedance of 8 Ohms or 4 Ohms. Using speakers that have an impedance lower than the amplifier rating is likely to increase distortion and can damage the outputs of the amplifier if the levels are too high. Using speakers that are significantly higher than the minimum rating will not cause damage to either the amplifier or speakers but it will reduce the power that is delivered to the speakers. In most domestic systems, this limitation of the power output is not likely to be an issue. Any amplifier rated to drive into 4 Ohms will work well with speakers of between 4 and 8 Ohms. An amplifier with an 8 Ohm rating should be used only with speakers of 8 Ohms or higher.
Will 6 ohm surround sound speakers work with an 8 ohm amplifier?
It's a myth. There is really no 8 Ohm amplifier on the market. And there never was. The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout
Can 8 ohm speakers be used 4 ohm surround sound system?
It physically can but that is like putting the wrong amount of water through the wrong size pipe. It will work for awhile but something is going to give. In your case that risk involves a fire hazard. I wouldn't do it.
What size audio amplifier will you need to buy to power four 60 watts speakers 8 ohms impedance Frequency Response 120 Hz - 20 kHz?
There are several ways to drive four speakers. For simplicity, this answer assumes that the amplifier will be a two channel stereo amplifier - one channel for left and one for right hand channels. It also assumes that the speakers will be connected in parallel, that is, both positive terminals wired together and both negative terminals together. The two speakers together will be the equivalent of a four ohm speaker. First, make sure the amplifier is rated to drive four ohms to both the left and the right speaker. Most amplifiers will handle a four ohm load but some are aonly designed for eight ohms. The manual will tell you what the amplifier can handle. The speakers can handle up to 120 Watts per channel when two are used together. To fully drive the speakers, an amplifier of 120W per channel will be needed. However, that is the worst possible size of amplifier to use if you are going to run the system near its peak power output. Here's why: Speakers are able to cope much more power than their rated power. The sound will be terrible but generally, the speakers will not be damaged. Speakers can also cope with a distorted signal from an amplifier as long as the power level is a lot less than the rated speaker power. However, overdrive the amplifier when it is delivering the full power rating of the speaker and the high power distortion is very likely to cause damage to the speaker. The choice of amplifier should either be higher or lower than the speaker rating. A 30W per channel amplifier will still have a great deal of power to offer and the output will be far louder than most people would ever want in a living room. If the amplifier is over-driven, the low power level avoid speaker damage. A 200W per channel amplifier will drive the speakers harder but with a clean signal. If you want to run the speakers close to their maximum level, choose an amplifier of this power output or higher. A note about power levels: True power output is always measured as an RMS figure. Music power is approximately twice RMS power and peak music power is about twice the level of music power. Therefore, if the speakers are rated at 60W peak music power, they actually have a rating of just 15 Watts RMS. When comparing amplifiers and speakers, always make sure you use the same units, RMS, Music or Peak Music. Never mix them.
Will a 4 ohms speaker work with a 16 ohms amplifier?
An amplifier that is rated to drive a 16 ohm load will not perform well if a 4 ohm load is applied to it. The output rating is calculated to allow the highest power output from the amplifier. If a 4 ohm speaker is used instead of the recommended 16 ohm speaker, the current output will be far higher for a given output voltage. Although the amplifier will drive the speaker at low levels, as the volume is increased, the output current may rise to the point where it will damage output transistors or perhaps the main power supply. Some 16 ohm rated amplifiers may well handle 4 ohm speakers without damage but the only way to find out is to try it - meaning a dead amplifier if the test isn't successful. So, just like my previous answer (what happened to it?), the answer is YES but not as well.
How many speakers can go into a single stereo system?
All amplifiers are rated to handle a certain speaker impedance. The majority of loudspeakers have an impedance of 8 ohms while most amplifiers will be able to drive a minimum load of 4 ohms. It is important to check the ratings of the amplifier before adding more speakers. If two 8 ohm speakers are wired in parallel, the total impedance will be 4 ohms. If 3 speakers are wired in parallel then the total impedance will reduce to around 2.5 ohms. If the total speaker impedance is lower than the rated impedance of the amplifier, it is quite possible to damage the amplifier as the output level is increased. To be safe, make sure you understand the impedances of the speakers and the amplifier's rating before hooking anything up.
If an amplifier has an output of 350 watts rms 8 ohms what is the output at 4 ohms?
There is no amplifier with an output impedance of 8 ohms or 4 ohms on the market. All audio amplifiers really have an output impedance of less than 0.1 ohms. Scroll down to related links and look at "Amplifiers, loudspeakers and ohms"
What are typical values of input impedance and outoput impedance of ce amplifiers?
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
Will 8 ohm speakers work with 816 ohms of impedance?
yes but will barely hear anything. If you have 816 Ohms of impedance then your speaker is probably bad.
How do you select speakers with respect to the impedance of the amplifier?
Amplifiers are rated to operate within a range of impedances. Typically, a domestic amplifier will drive a minimum impedance of 8 Ohms or 4 Ohms. Using speakers that have an impedance lower than the amplifier rating is likely to increase distortion and can damage the outputs of the amplifier if the levels are too high. Using speakers that are significantly higher than the minimum rating will not cause damage to either the amplifier or speakers but it will reduce the power that is delivered to the speakers. In most domestic systems, this limitation of the power output is not likely to be an issue. Any amplifier rated to drive into 4 Ohms will work well with speakers of between 4 and 8 Ohms. An amplifier with an 8 Ohm rating should be used only with speakers of 8 Ohms or higher.
How many ohms do you need for 4 overhead speakers?
You need some amplifiers.
How do you use 16 ohms speakers with 8 ohms amplifier?
On any given day you can hear manufacturers, distributors, sales people or even customers talking about amplifiers with a "4 ohm output" or an "8 ohm output". You might even hear them refer to something called an "8 ohm amplifier" if they have a loudspeaker with this impedance (resistance) that they wish to connect. This is a rather unfortunate and also inaccurate use of technical language. There are no 8 ohms amplifiers on the market. The source impedance will be less than 0.5 ohms.
What kind of desk to use for 8 ohm amplifiers?
The output impedance of a power amplifier is always less than 0.1 ohms. There are no 8 ohm amplifiers on the market!
How do you connect 4 ohm speaker to 16 output amplifier?
No Problem to do this, but there are really no amplifiers with an output impedance of 16 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Can 8 ohm subs be used on 4 ohm amps?

Can you use 10 ohm speakers with a 4-8 ohm receiver?
You can use your so called "4 to 8 Ohm's output" amplifier for your 10 ohms loudspeaker. All amplifiers have an output impedance of less than 0.5 ohms. You use impedance bridging when you connect the 10 ohm's loudspeaker. The "4 to 8 Ohm's output" means only that a 4 to 8 ohm loudspeaker will be adequate and not that the output impedance is 4 to 8 ohms! Scroll down to related links and look at "Impedance bridging - Wikipedia".
How do you parallel 2 speaker 8 ohm on 8 ohm amply?
