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.
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.
16 Ohms. Yes 16 ohms in series. 4 ohms 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.
wire two 8 ohm speakers in a parallel circuit!
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.
If wired in parallel then 4 ohms.
in parallel No. Two 8 ohm 'speakers in parallel present a 4 ohm load.
they are probably 4 ohm
yes
Yes
Sorry, but there is really no 4 ohm or 8 ohm amplifier. We use only voltage bridging. Scroll down to related links and look at "Interconnection of two units".
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".

if you put 2, 8 ohm speakers together on the same channel you will trick the amp into seeing a 4 ohm load, it is not advisable to run a 8 ohm coiled speaker on a 4 ohm amp unless you do the above. So if you want to run 2 8 ohm speakers from a 4 ohm amp this will work the best although the amp will need to be hefty as its worse to underpower a sub than overpower it! I have used a 8 ohm speaker myself on a car amp and had no problems but it was not a cheap entry level amp! some amps will take it, others will get hot and enter protection mode. Hope this helps!!!
Of course! As long as your amp's minimum impedance is 4 ohms or lower.
