yes you can you will have to wire up the speakers in parallel because with 8ohm it gives too much resistance and the amp will produce unwanted sound i.e. low volume.
Your question doesn't fully make sense. Let me see if I can answer part of it. If your amp puts out 220 watts, the speakers should be rated for at least 220w, or they may be destroyed if you turn the amp all the way up. Watts are a measurement of power, in the case of speakers they are rated for how much power (watts) they can handle. Ohms is a different thing altogether. Ohms are a measurement of resistance to electrical flow. Amps are usually rated to work with certain impedance level speakers (4 ohm, 8ohm, 16ohm, etc.) the lower the ohms, the harder the amp works. I know it seems backwards but it isn't. each amp is different so you would have to read the amp's spec sheet to see what they reccomend. I have no idea what you are asking for with the "12 DC" thing.
If the amplifier is not rated for 4 ohms impedence, you will quickly over-current the amp, burning out components. The power handling of the speaker and power output of the amplifier does not matter in this case. It must be compatible with the impedence load that you are connecting.
It depends on the application. If you have an amp that is stable in 8 ohms per channel, then 8 ohm speakers will work best. However, if you wanted multiple speakers on that channel you could use two 16 ohm speakers.
You always want to buy speakers rated higher than the max RMS output of the amp. I've blown plenty of speakers in my day as soon as I turned it on.Ohms is just as important. Never connect two or more speakers in parallel. This cuts the ohms to less than half and you will blow the amp if its not designed for it . You can connect speakers in series if you like but this cuts your RMS output to less than half and also could blow the amp. One speaker per channel and keep the gain nob one level below max to be safe.Car amps 4 ohms speakers.House amps 8 ohms unless specified.That answer (above) is not much help, nor true. (I wouldn't trust someone who has blown "plenty of speakers", it sounds like a poke and hope job.) Unfortunately, the correct answer is hard to obtain because the people who sell amplifiers and speakers don't always use the RMS power rating for CONTINUOUS power when describing the components. These manufacturers know that we folks are into POWER and they usually advertise the components "PEAK" power rating. WOO HOO!But bottom line, it's easier to blow the amp with higher rated speakers because the the amp is working too hard to fill that big jug so to speak. The rule is to get an amp with about twiceas much RMS value of wattage at 8 ohms as the speakers RMS value at 8 ohms. You'll need to leave the room because your ears will be throbbing before you'd do any damage to your speakers.But yes, it's always important to follow these steps and be sure to connect your speakers and inputs (mikes, instruments, etc.) first, AND have the power level controls SET LOW, then power up, and then adjust the volumes up until you get your sound right.Connecting speakers in parallel is a whole different topic, but it LOWERS the ohms resistance and yes, it takes lesser wattage to blow them.
1 amp.
the watts for 2 ohms is more than 4 ohms. depending on the ohms your speakers take up and the wattage the speakers use, tells you what size amp you need.
Two four ohm speakers in parallel is two ohms. Make sure the amp is rated for that load impedance, or you could damage it.

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.
The speaker will be fine and there will be little impact on its performance. In these situations, if there is a problem, it will be with the amp because that is what delivers the electrical current to the speaker. The situation you want to avoid is having speakers with a lower impedance connected to your amplifier. So you might have had a problem if your surround speakers were 4 ohms. However, as they have a higher impedance than the amp is set for, I wouldn't worry about it.
Series connection is connecting a - to one speaker and a + to another. Then connecting each speaker from + to - together thus combining them. In series a speakers ohms are added. For example you amp is rated to produce as low as 4 ohms per channel. On one channel you have a 4 ohm sub and a 6 ohm speaker connected in series. This will produce a total of 10 ohms which have a lower sound to it but be better for the amp. Parallel connection is exact opposite and is done to decrease ohms thus increasing the amps power per channel. This is very easily done you run power from an amp to one speaker then connect that speakers +/- to another +/-. Be careful by doing this you lower the ohms, don't go too low you will damage your amp. A 4 ohm per channel amp should not run any lower than its recommended ohms as it will burn out. For example you have a 4 ohm amp and you want to parallel two 6 ohm subs. This will produce 3 ohms on that channel, which the amp is only rated for 4 ohms thus this will burn it out. Check your amps rating and your speakers ohms before parallel or series wiring them together. Your safer bet is series wiring, the louder one is parallel wiring. You can parallel and series wire together but make sure you have an even amount for example 2 speakers series together and 2 paralleled together. It is your own opinion on what to do if you want a safer sound series them, a louder sound parallel them.
Depends on the impedance of each speaker. If they are car subs and not converted home speakers, they are probably 4 Ohms each. Depending on how you wire them you get either 8 Ohms or 2 Ohms. 8 Ohms is not a problem load-wise for the amp, but if it is rated at 100 watts into 4 Ohms, then you will only get 50 watts into 8. Many car subs nowadays will handle a 2-Ohm load, but some will not. Your two speakers will handle 2x150 watts or 300 watts. An amp that is rated to drive 300 watts into 4 ohms will either deliver more like 500 watts into 2 Ohms, or it will melt through the floor of your car. So you need to look up the specs for your amp in the instruction manual. If it will only run into a 4-Ohm load, you can only use one 4-Ohm sub per channel. If it will handle a 2-Ohm load, you will have to turn it up slowly or you will blow your speakers out. Mr Ohm and his law will not be denied.
You can wire and amp down to 0.3 ohms by decreasing its windings.
Depends on the amp and type of speakers brand and ratings would be nice info u also need to look at ohms of the amp and the speakers
If your sub is 2 ohms and your amp is 2 ohm stable, your done. Your amp will be at 2 ohms because the sub is 2 ohms.
If the amplifier is not rated for 4 ohms impedence, you will quickly over-current the amp, burning out components. The power handling of the speaker and power output of the amplifier does not matter in this case. It must be compatible with the impedence load that you are connecting.
It depends on the application. If you have an amp that is stable in 8 ohms per channel, then 8 ohm speakers will work best. However, if you wanted multiple speakers on that channel you could use two 16 ohm speakers.
