Can resistance be added to speakers to make a 4 ohm speaker have an 8 ohm load?

You "can" add a four ohm resistor in series with a four ohm speaker, and make it look like an eight ohm speaker, however, the frequency response will not be the same. It is better to use to correct speaker for the amplifier, or use two four ohm speakers in parallel.
That resistors power rating must exceed the rating of the speaker. Half the from the amplifier will go to the speaker, while half will go to the resistor, making it get quite hot.

Is every resistance load resistance?
No. Load resistance is the value of the element actually doing the work of the circuit it is connected to. A speaker connected to an amplifier is the load.
What ohm should the speaker be if i want to achieve a 2 ohm load from 4 speakers?
Four 8 ohm speakers wired in parallel would give an effective 2 ohm load.
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 would make a 1992 oldsmobile's radio smoke?
the factory radio is bad on the inside or speaker ohm load is different are your speakers aftermarket?
How does load current varies with the load resistance?
Load current is related to load resistance by an inverse relationship. The load current increases linearly as load resistance decreases. Remember, the less resistance, the more current.
Can you attach additional speakers to the Bose 123 system?
In short, yes. you can add speakers to nearly ANY setup. however, you should be sure to add enough speakers with particular resistance (load/ohms) ratings in order to wire them in parallel and series so each channel has the same total ohms as the original speaker. If the total load on each channel is too high or too low, you could risk overheating the power source (head unit/amplifier), some headunits or amplifiers have built in safety mechanisms which turn off the unit if the load is either too high or too low. Keep in mind, when adding speakers, the power from each channel is split between them. For example, each speaker may get 100 watts, but if you add a speaker to each channel, each speaker will only get 50 watts. Not only this, but keep in mind Bose made some very specific connectors so you will have a hard time to add and connect the extra wires. The system is in no way made for this.
How do i Make a 8 ohm speaker 16 ohm?
You can't change the ohm load of a speaker. What you can do, is get a second 8 ohm speaker to run with that speakers in series and you will get a total ohm load of 16 ohms.To run them in series, simply wire the positive terminal of one speaker to the negative of the other speaker. One speaker will have an open positive terminal which you wire to the positive terminal on the amp, and same goes for the negative on the other speaker (to the amp's negative terminal of course).
Does a speaker selector only allow you to use one set of speakers at a time?
It can depend on how it is wired. Generally one would assume that a speaker seletor is for one set of speakers. It is possible to wire a selector to connect more than one set, but one should be aware that if putting speakers in parallel the impendence will be lowered, e.g. two 8 ohm spks in parallel will equal a 4 ohm load or appx half the original value, if the load gets to low, e.g. 2 ohms or less, the load can look like a short across the speaker terminals and cause the amplifier overload and burn out the output.
What will happen when source resistance equals load restiance?
when source resistance and load resistance are equal maximum power is transfered
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.
What is the definition of the resistance arm?
The resistance arm is the side of the lever (from the fulcrum to the load) that carries the load.
Is load the same as resistance?
Depending on who is asking about, it could be. But strictly speaking, no. When referring to "load", this could be resistance and reactance (Load at a certain power factor).
