If you connect four four-ohm speakers in parallel, the impedance will be equal to 1 ohm, and will allow the speakers to run at the advertised watt RMS. The equation is 1/(total impedance) = 1/(impedance 1) + 1/(impedance 2) and so on.
Parallel is like this:
Power source: +
Speaker+: + + + +
Speaker-: - - - -
Power source: -
However, usually if you hook up a 4 ohm speaker to a 1 ohm amplifier, it would still function it would simply not provide nearly as much wattage as it would have otherwise.
Also, if your speakers are dual voice coil (like many subwoofers) you could use 2 4 ohm speakers, connecting the two voice coils on each speaker in parallel and then connecting the speakers themselves in parallel.

Will wiring a 16 ohm woofer with a 16 ohm tweeter in parallel result in a total ohm load of 8 ohms?
If you mean as pairs, yes. put an 8 Ohm and a 16 Ohm speaker in parallel for each channel. The 16 Ohm speakers will take 1/3 the power and the 8 Ohm speakers will take 2/3 the power. The resulting impedance will be 5.33 Ohms.
Can you run 4ohm resistor to make 4 ohms speakers 2 ohm?
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.
What is affect of using a 3 ohm speaker with a 100 Watt amplifier?
Amplifier power and impedance are not related, although a lower impedance speaker will be louder. Most home stereos cannot drive loads below 4 ohms, however, so using this 3 ohm speaker with a home theater may cause the amp to go into protection mode or shut down completely. Check your owner's manual to see what impedance of speaker your receiver can safely drive.
A 3 ohm 2 ohm and a 5 ohm resistor are in series What is the total resistance in ohms of the system?
10 Ohms.
How would you connect 1- 4 ohm 40 watt speaker and 1- 6 ohm 35 watt speaker to left output of an AV receiver with 8 ohm and 110 watt output. Same combo for right output?
The 2- 4 ohm speakers can be hooked up in series to make 8 ohms. you cant hook up the 2- 6 ohm, cause if you put them in series, you have 12 ohms. If you put them in , parallel you have 3 ohms out from av to +(4ohms), -(4ohms) to +(4ohms), -(4ohms) to - av. And do the math 4ohms plus 4ohms equals 8ohms. doing the math on the 2- 6ohm speakers... 6ohms + 6 ohms = 12ohms I dont think 12ohms would blow your system, but it wont sound right. now if you raise the volume too loud on the av you will blow the speaker coils out you may boost the wattage of the 2-4ohm speakers (in series) to maybe 70 watts total ******************************************* If you connect loudspeakers in series, the amplifier can not properly damp them, but, unless you are a fairly critical listener, you perhaps won't detect the difference. Connecting two 6 ohm 'speakers in series will give a load of 12 ohms, and will not "blow" anything. Connecting a load impedance higher than the amplifier's design load will do no harm at all. The only disadvantage is that the amplifier will not be able to develop its rated power output.

What are the speaker sizes in your 2001 Saab 9 3?
In the 9-3 you have 3 1/2 inch speakers up on the dash. The cover just pops off with a flat head screwdriver. The rear speakers in the hatch area are 6x9's. And in the doors are 6 1/2 subs. All the speakers are 2 ohm speakers. So if you replace the speakers and keep the rest of the factory stereo make sure that you upgrade to 2 ohm speakers such as Infinitys. If you upgrade to 4 ohm speakers, which most speakers are, you will get less volume out of your factory stereo. The reason behind this is that the car's factory amp will then be placed at a 4 ohm load which will cut the power output to half spec. Less power, less loud music. And you will notice a big difference.So that's it. It is very easy to replace the speakers on the Saab so do not worry. You do not need to be a pro or anything.Comment re: answer. I have a 2000 9-3 and the factory rear shelf speakers were clearly marked as being 4 ohm speakers. So I'd be careful about assuming they are all 2 ohm. In fact, the front door speakers are 2 ohm and the rears are 4 ohm. This link (toward the bottom has the ohms for each speaker: http://www.mitt-eget.com/saab/faq_audio.shtml#as2_amplifier The base is "Premium" and "Prestige" is the better sound system. I installed 4 ohm in the Premium rear and they seem to be working great. New Comment: My 2000 9-3 Convertible has 4 ohm in the doors and 2 ohm (6.5 inch) in the rear. The rears are cheap-ass whizzer cones with an itty-bitty second order crossover.
Are the speakers in the thunderbird 3 way?
the speakers in the thunderbird are standard paper cone speakers. They are not 3-way though the stock amp in my 95 had plenty enough to drive 4 4-way speakers that i put in it.

How do you ruduce ohms on speakers on a 12 volt car stereo 25 watts system the speakers are 2 ohms and stereo is 4 ohms?
That should work fine...matching is not critical. However if you want to be "pure", you could: 1...Insert a 2 ohm resistor in series, but that reduces damping and you may get coil resonances. 2...Install a 2 ohm to 4 ohm transformer. Hard to find and expensive. 3...Install two speakers in series, remembering to phase them correctly.
What is the smallest number of resistor to provide 4 ohm if only 3 ohm are available?
4, 1 3 ohm resistor in series with 3 3 ohm resistors in parallel.
Will a 4 ohm amp work with a 8 ohm receiver?
Yes, if you use two 4 ohm speakers or or one 4 ohm resistor and a 4 ohm speaker to equal the 8 ohm resistance per channel. An important thing to note about this, is that you will need to make sure you get a resistor that can handle the current. You can go higher in resistance but not lower, it must be equal to or higher. Something important is added: The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout
