If the amplifier is designed for an 8 ohm load, then you should use an 8 ohm load.
Three 8 ohm speaker in series is 24 ohms, and in parallel they are 2.67 ohms. Neither of those is a good match for an 8 ohm rated amplifier.
If you do this, you will not achieve rated power, and you may well damage the amplifier.

If you replace a 4 ohm speaker with an 8 ohm speaker can the amplifier blow the speaker?
A1: The output impedance of a power amplifier is always less than 0.1 ohms. There are no 4 ohm amplifiers on the market! A2: I actually just bought a new car radio/CD player that specifically shows 4 ohm speakers on the sticker. It is designed to work optimally with 4 ohm speakers. If you use 8 ohm instead, it will work, but you will not get the full power output that is specified. The amp can only kick out so much voltage and so much amperage - if it is designed for 4 ohm speakers, and 200 watts (stereo, so 100 watts per speaker), it can supply 20 volts (P = V^2 / R). If you used 8 ohm speakers to this amplifier, each speaker would only get 50 watts powered at full output voltage. Alternatively, if it is designed for 8 ohm speakers and 100 watts per speaker, it can provide 40 volts. If you used 4 ohm speakers instead, each speaker could be given 200 watts at 40 volts, resulting in severe overheating and damage to the amplifier.
Can you play 8 ohm speakers on a 16 ohm amp?
There is no 8 ohm solid state amp. Really! The output impedance of such an amp will be arround 0.4 ohms. Scroll down to related links and look at "Interconnection of two units- Voltage Bridging - Zout < Zin".You can, as long as the amp's impedance is much lower to the speaker(s) total ohm load you're fine. We have never impedance matching there.
Can a 4 ohm receiver drive 3 ohm speakers?
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 6 ohm speakers work with 8 ohm amp?
There are no 8 ohm amplifiers!The amplifier will have an output impedance of around 0.08 ohms. In hi-fi we have always impedance bridging. Zout
Can a 8 ohm speaker replace a 6 ohm speaker?
You need to find out how many ohm's your deck is pushing out and make sure you have the right grade speaker wire so you don't under power the speakerRubbish. A "deck" doesn't "push out" ohms.An amplifier is designed to develop a stated power in a stated impedance, and that is based on the amplifier's ability to deliver current.An amplifier designed to deliver maximum output to a 6 ohm load can safely drive an 8 ohm one. But it will not be able to develop its maximum power.
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
2 ohm stable amp can you wire up your four 4 ohm svc speakers too 2 ohm?
I think if you have 2 subs, you have to wire them in parallel so they are both loaded to 4 ohms, then the amplifier will see a 2 ohm load. what amp are yu using? im planning on getting a 2ohm stable class d mono amplifier for my 4 ohm DVC Subs. You need to wire both positives to one positive input and both negatives to one negative input for parallel wiring. That's what ive learned. Since your amplifier is stable at 2 ohms, you shud get a lot of power.
Will 4 5.5 ohm speakers connect to an amplifier with a 16 ohm output impedance?
Yes, they will. One can connect anything to anything else. Will it work? If so, how well? Is it safe? If the four speakers are connected in series, the total impedance of the speakers will be the sum of all the impedances of the speakers: 5.5 + 5.5 + 5.5 + 5.5 = 22 ohms The 22 ohm load on the amplifier will be a bit higher than the amp has been designed for, but the setup will work. At modest power levels it is doubtful that anything audible will be noticeable because of that slight mismatch, and as long as one doesn't crank it up too high, the amp won't notice the difference. It would be wise when hooking up the speakers to insure they are all hooked up in phase... Something important has to be added: There is really no 16 ohm amplifier on the market. The amplifier will have an output impedance of around 0.08 ohms. In hi-fi we have always impedance bridging. Zout
Can you series two 4 ohms speakers?
Yes, you can run a pair of 16 ohm speakers in series. The resultant impedance would be approximately 32 ohms. Assuming constant voltage, this would result in one quarter the original power to both speakers, or one eighth the original power to each speaker.
What exactly is a combo amp and how is it different from a normal guitar amplifier?
A combo amplifier for a guitar contains a normal guitar amplifier and one to four speakers. A normal guitar amplifier does not contain speakers, but is able to send the signal to a speaker cabinet.
What happens when you have a 4 ohm and a 2 ohm sub hooked up to an amplifier?
Yes, you can wire a 6 ohm sub with a 4 ohm sub to the same amplifier, but you need to verify that the amplifier can handle the resulting impedance of 2.4 ohms - many cannot, and could be destroyed. Also, realize that the power in the 4 ohm sub will be greater than the power in the 6 ohm sub.
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.
