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".

How do you connect a 2 ohm amplifier to a 4 ohm speaker?
Yes you can. 2 ohms is as low as you can go with that amp MOST car subs have 4 ohm voice coils. The bigger the number, the less low bass frequency run two single voice coils subs and you'll be fine. It's a myth. There is really no 2 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 << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. Zout = Zin/Df. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 4 ohms, the output impedance of the amplifier is Zout = 4 / 200 = 0.02 ohms. You see, there is no "2 ohm amplifier" on the market with a 2 ohm output impedance. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
Is a 4 ohm subwoofer better then a 8 ohm subwoofer?
You need to match the speaker with the amplifier. Better or worse is not the question. The question is dynamic range and the possibility of overloading the amplifier. If the amplifier is rated 4 ohms, use a 4 ohm speaker. Same for 8 ohms. Do not "mix and match".
Will 8 ohm speakers work with a 4 ohm amplifier?
Yes, you can use 2 in series, IE daisy chain them to add up to 8 ohms.For stereo you would need 4 speakers not 2. mono, 2 not one.Most Amplifiers work OK driving to a lower impedance loads anyway so just hook them up. Very high power levels may overheat the amp but at normal volume it should be fine. Something important is added: There are no 8 ohm amplifiers! The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout
Will 4 5.5 ohm speakers connect to an amplifier with a 16 ohm output impedance?
Yes, they will. One can connect anything to anything else. Will it work? If so, how well? Is it safe? If the four speakers are connected in series, the total impedance of the speakers will be the sum of all the impedances of the speakers: 5.5 + 5.5 + 5.5 + 5.5 = 22 ohms The 22 ohm load on the amplifier will be a bit higher than the amp has been designed for, but the setup will work. At modest power levels it is doubtful that anything audible will be noticeable because of that slight mismatch, and as long as one doesn't crank it up too high, the amp won't notice the difference. It would be wise when hooking up the speakers to insure they are all hooked up in phase... Something important has to be added: There is really no 16 ohm amplifier on the market. The amplifier will have an output impedance of around 0.08 ohms. In hi-fi we have always impedance bridging. Zout
What power of amplifier do i need for 6 ohm speakers to connect them to my computer?
Most power amplifiers will handle a load of 6 ohms. The spec you need to look at is the power handling of the speakers. If they are rated for 100 watts program power, then look for an amplifier rated for 100 watts RMS output. Any amplifier can be connected with adapter cables to the typical 1/8" output of your computer.
Will 8 ohm speaker work with 4 ohm bass guitar amplifier?
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.
How do you connect 2 6 ohm speakers to an 8 ohm amplifier?
You can, but its power output will be a bit higher than its 8 ohm rating.
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.
Can a 8 ohm amp power a 4 ohm speaker?
You will find no 4 ohm amplifier! So you will need no transformer. All audio amplifiers have output impedances of lower than 0.5 ohms. We have "impedance bridging" between amplifier and loudspeaker - no matching. Scroll down to related links and look at "impedance bridging - Wikipedia".
If you replace a 4 ohm speaker with an 8 ohm speaker can the amplifier blow the speaker?
A1: The output impedance of a power amplifier is always less than 0.1 ohms. There are no 4 ohm amplifiers on the market! A2: I actually just bought a new car radio/CD player that specifically shows 4 ohm speakers on the sticker. It is designed to work optimally with 4 ohm speakers. If you use 8 ohm instead, it will work, but you will not get the full power output that is specified. The amp can only kick out so much voltage and so much amperage - if it is designed for 4 ohm speakers, and 200 watts (stereo, so 100 watts per speaker), it can supply 20 volts (P = V^2 / R). If you used 8 ohm speakers to this amplifier, each speaker would only get 50 watts powered at full output voltage. Alternatively, if it is designed for 8 ohm speakers and 100 watts per speaker, it can provide 40 volts. If you used 4 ohm speakers instead, each speaker could be given 200 watts at 40 volts, resulting in severe overheating and damage to the amplifier.
Will a 4 ohm amp damage a 2 ohm speaker?
No, but it may be the other way around. Since you're using a 2 ohm speaker, don't expect the volume to be louder since the speaker uses twice as much power than a 4 ohm speaker does. If anything, I'd be cautious about the amp having the ability to handle the extra load. It's a myth. There is really no 4 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 << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. Zout = Zin/Df. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 4 ohms, the output impedance of the amplifier is Zout = 4 / 200 = 0.02 ohms. You see, there is no "4 ohm amplifier" on the market with a 4 ohm output impedance. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
What is the purpose of common collector voltage amplifier where voltage gain is unity?
It is a current amplifier. It can be used to boost current in an output stage to a speaker, for example, or for circuit isolation (two of many purposes). If you took a differential amplifier output stage to an 8 ohm speaker, it is very likely you would load the amplifier to the point of making it worthless (it would not amplify).
Can you power 8 ohm speakers with a 4 ohm amplifier?
Yes, but you won't get rated pwer. Best is to match the speaker to the amplifier.
Can you connect an 8 ohm head to a 4 ohm cabinet?
Sorry, there is no 4 ohm amplifier in the world. It's a myth. A loudspeaker amplifier has an output impedance of less than 0.5 ohm. In hi-fi we have always impedance bridging. Zout << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. Zout = Zin/Df. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 4 ohms, the output impedance of the amplifier is Zout = 4 / 200 = 0.02 ohms. You see, there is no "4 ohm amplifier" on the market with a 4 ohm output impedance. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
Can i make 4 ohm output amp switch to 8 ohm..?
There is neither 4 ohm nor a 8 ohm output of an amplifier. Less than 0.5 ohm is the output impedance of a loudspeaker amplifier. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
Can an 8 ohm speaker be driven safely by a 16 ohm Guitar amp?
It's a myth. There is really no 16 Ohm guitar 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 << Zin. That means the output impedance of the amplifier is much less than the input impedance of the loud speaker. The damping factor Df = Zin / Zout tells you what Zout is. Zout = Zin/Df. If the damping factor Df = 200 and the loudspeaker impedance is Zin = 16 ohms, the output impedance of the amplifier is Zout = 16 / 200 = 0.08 ohms. You see, there is no "16 ohm amplifier" on the market with a16 ohm output impedance. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".
What is the Difference between 4 ohm to 8 ohm output?
There is really no amplifier on the market which has an output impedance of 4 ohms or 8 ohms. The impedance of an amplifier is always less than 0.5 ohms. We do not use matching, we use bridging when we connect the amplifier to the loudspeaker. Scroll down to related links and look at "Interconnection of two audio units".
