The amplifier will have an output impedance of around 0.04 ohms. There will be no 8 ohms. In hi-fi we have always impedance bridging. Zout << Zin.
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 = 8 ohms, the output impedance of the amplifier is Zout = 8 / 200 = 0.04 ohms.
You see, there is no "8 ohm amplifier" with a 8 ohm output.

What is the equivalent resistance of a pair of 4 ohms resistor in parallel?
Four 4 ohm resistors in parallel have an equivalent resistance of 1 ohm. Two resistors R1 and R2 in parallel have an equivalant resistance of R1R2/(R1+R2). Plug in 4 ohms for two of the resistors and you get 2 ohms. Repeat and you get 1 ohm.
How will you join 3 resistors of 2 ohm each so that the effective resistance is 3 ohm?
You can achieve an effective resistance of 3 ohms by connecting the resistors in series. Connect two resistors in series to get a combination of 4 ohms. Then, connect this combination in parallel with the third resistor to achieve an overall resistance of 3 ohms.
How many volts are required to push 3 amps through a resistance of 4 ohms?
Just use Ohm's Law: V=IR (voltage = current x resistance; using units: volts = amperes x ohms).
An electric DC circuit is attached to a 12 volt battery and has a 3 ohm resistor in it find the current flowing through the circuit?
If the 3-ohm resistor is the ONLY thing in the circuit, then the current flowing through it is (12 volts)/(3 ohms) = 4 amperes. If there are other things in the circuit besides the resistor, then the current depends on all of them.
A 4 ohm resistance wire is doubled on it calculate the new resistance of the wire?
The resistance of a wire is directly proportional to its length, so doubling the length will also double the resistance. Therefore, doubling the 4 ohm resistance wire will result in a new resistance of 8 ohms.
How many ohms would 2 16 ohm speaker cabinets and 1 8 ohm speaker cabinet calculate out to be?
If wired in parallel then 4 ohms.
What is the ohm's on Chevy Colorado speaker?
4 Ohms. Can use any standard 4 Ohm speaker as long as you don't chassis ground it.
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".
Can you convert an 8 ohm speaker into 4 ohms?
Yes It all in how there wired up
If an amp runs 1000 w rms at 1ohm how do you wire a dual 4 ohm speaker to run at 1 ohm?
the impedance of a speaker is a characteristic that is has. A 4 ohm speaker will always have a 4 ohm impedance and it cannot be changed. If 2 speakers of 4 ohm impedance are wired in parallel, then the total impedance will be 2 ohms. Similarly, if you wire 4 speakers together, the total impedance will be 1 ohm. Wiring a 2 ohm speaker to an amplifier rated to drive a 1 ohm load should work without any problems but expect the total power output to be somewhat lower than with a 1 ohm load.
Can you bridge an 8 ohm speaker to 4 ohms?
Ohms is a measure of resistance. When the electricity passes into the speaker, some of it is 'resisted.' The ohms rating of the speaker is how much is resisted, and an indication of how much energy it takes to drive it - the higher the ohms rating, the more difficult it is to drive.
Can you run 4ohm resistor to make 4 ohms speakers 2 ohm?
Yes, you can safely use a 4 ohm amp with one 8 ohm speaker, but you will not achieve full power. The 4 ohm amp is designed to supply a certain voltage into a 4 ohm speaker. Supplying that same voltage to an 8 ohm speaker will result in half the power, or -3dB. For maximum power, use a 4 ohm speaker, or two 8 ohm speakers in parallel.
What is the resistance of four 8 ohm speakers wired in a series?
Two 8 ohm speakers in parallel is 4 ohms, and the power will be split between them. However, unless the amplifier is rated for 4 ohm operation, you will not get the same total power out of the amplifer as you would with an 8 ohm load.
What is the different between 2 ohm and 4 ohm?
The difference between 2 ohms and 4 ohms is 2 ohms.
What ohm load will 4 12 in dual 2 ohm play at?
There are a lot of possibilities here, especially since your question is worded exactly right.I'm taking it you have 4 12" speakers, each of which have Dual Voice Coils (2 Ohms each). You want to wire them together and see what ohm load you have.Ok, there's multiple ways to wire this up. Series, Parallel, and Series/Parallel combo.Wiring these speakers in series can give you either a 4 ohm load, or a 16 ohm load. 4 ohms if each speaker by itself (having DVC) is wired in parallel and 16 ohms if each speaker by itself is wired in series.Wiring these speakers in parallel can give you either a .25 ohm load, or a 1 ohm load. Again .25 ohms if each speaker by itself (having DVC) is wired in parallel and 1 ohms if each speaker by itself is wired in series.Wiring these in a series/parallel configuration can give you tons of different wiring options and ohm loads. In your case .75, 1, 3.2, 4 ohm loads.So your best option would to be wire your speakers up in series, with each speaker wired in parallel to itself. This way you'll get a 4 ohm load, if done properly. Make sure your amp can run a 4 ohm load too.
Can I safely run 4 x 4ohm speakers with an 8 ohm rated amplifier?
Not really. The only possible configurations of four 4 ohm speakers is 1 ohm, 4 ohms, and 16 ohms. This will not match an 8 ohm rated amplifier. It will work, but you will not achieve rated power output, and you run the risk of damaging the amplifier.
Can you put 4 ohms into 16?
Sure, If you mean your stereo has 4 ohm output and using 16 ohm speakers. The volume will be reduced somewhat by doing this, but it won't harm the stereo. If you have 4 ohm speakers and stereo is designed for 16 ohms you can do it ,but the amp will run hot and you may suffer damage at high volume to the amp.
