Yes, but you need a big industrial chopper/mixer!
Really need more information here. The total will be 2.67 ohms. If it is a solid state amp that is rated to go down to 2 ohms you should be OK. The 4 ohm speaker will get receive twice the power of the 8 ohm. If it is a tube amp that is designed for 2-3 ohms ( not likely) it would also be OK for the amp.
Yes, but the results will probably not be what you hope for. In most cases you will have significant reduction in sound quality. The impedance of 4 ohms in parallel with 8 ohms is just 2 2/3 ohms, and most amplifiers don't respond well to such a low value. Give it a try; it probably will not hurt anything.
Its not recommended. A four ohm speaker cabinet can be changed into an eight ohm speaker cabinet, if you have enough speakers in the cabinet in parallel that can be rewired in series. Unless you have a high end cabinet, the likelihood of this is small.Two four ohm cabinets, however, in series will be eight ohms. Keep in mind, however, that doubling the resistance will halve the current, which will quarter the power. Also, changing the impedance of a speaker system will change the frequency response, because often the filters are tuned with resistors.
I believe the ohm meter will read about 90% of the true ac impedance.
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.
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.
Yes. As long as the speaker impedance is higher than the minimum rating for the amplifier, you are OK.

If wired in parallel then 4 ohms.
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.
take a 2 ohm bridge into 1 ohm
Study ohms law to get your head around it.
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).
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.
Yes, but it will not be as loud as it would have been had a 6 Ohm speaker been used. Byt the way, the word 'Ohm' is capitalized, because it was someone's name.
You cannot make a 16 ohm speaker into an 8 ohm speaker. You would need to replace the voice coil. You can, however, put two 16 ohm speakers in parallel, and the equivalent impedance would be 8 ohms. The only remaining issue is frequency response, and that's a factor of speaker and enclosure design, so best is to use the exact speaker as originally designed.
4 Ohms. Can use any standard 4 Ohm speaker as long as you don't chassis ground it.
That would yeild a 4 ohm load
Only if your amplifier is capable of driving a 4 ohm speaker. Some have a switch on the back to select 4 or 8ohm speakers. Details should either be printed some where on the back of the amp or the instruction manual
