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".
There is really no amplifier with an output of 8 ohm or 4 ohm. All loudspeaker amplifiers have an output impedance of 0.5 ohm or less. Scroll down to related links and look at "Voltage Bridging".

In fact there is no "8 ohm output" on an audio power amplifier and no Zout = Zin. In audio technology voltage bridging is the normal connection method where Zout < Zin. Read the link: "8 Ohm Output" and "150 Ohm Input" - What is that?
Sorry, there is no amplifier with an output impedance of 4 ohm on the market. Scroll down to related links and look at "Interconnection of two audio units". Look for an amplifier and a loudspeaker.
you dont
There is really no 4 ohm amplifier. The output impedance of a good amplifier is less than 0.5 ohms. Scroll down to related links and look at "Voltage bridging or impedance bridging - Zout < Zin - Interconnection of two audio units".
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.
Only if your amp is rated to handle a 1 ohm load. If it's not you WILL... fry your amp.
First, you must know: There is no 4 ohm amplifier. All audio amplifiers have an output impedance of smaller than 0.5 ohms. So you use impedance bridging. No problem to connect the 0.5 ohm output to your 4 ohm loudspeaker. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Never haerd of a 10 ohm radio. There is no 10 ohm radio amplifier on the market, when you think that must be the output impedance of the amplifier. The output impedance of a radio amp is always less than 0.5 ohms. Scroll down to related links and go to "Voltage Bridging or impedance bridging - Zout < Zin"
nope
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!!!
