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 << Zin. The damping factor DF = Zin / Zout tells you what Zout is. Zout = Zin/DF. If the damping factor DF = 200 and the loudspeaker impedance is Zin = 8 ohms, the output impedance of the amplifier is Zout = 8 / 200 = 0.04 ohms. You see, there is no "8 ohm amplifier" with a 8 ohm output. Scroll down to related links and look at "Voltage Bridging - Zout << Zin".
Yes, but:
1.) if the amplifier is not rated for 4 Ohms, it may become overloaded at moderate volumes, overheat, and burn out.
2.) A 4 Ohm speaker will draw twice as much power from a typical solid state amplifier as an 8 Ohm speaker. Therefore the volume will be incorrectly high.
3. ) If you must use the 4 Ohm speakers, put a 4 Ohm resistor in series with them to make a total of 8 ohms. The speakers will play at half power. The resistor must be rated for half the power of the audio output channel in question. It may become hot and should be mounted away from items that might burn or melt.
Amplifiers are rated to operate with certain speakers. Most speakers on the market have an 8 ohm impedance and many amplifiers are designed to drive 8 ohm speakers. In most cases, an amplifier will operate with a 4 ohm speaker but there is a possibility that as the output level increases, the amplifier may be damaged due to excess current being drawn by the speaker.
With all amplifiers, it is worth checking the manual to see what the manufacturer advises regarding lower impedance speakers.
As an additional note, it is worth mentioning that amplifiers have an output impedance that is far lower than the rated load impedance. Therefore, there is strictly no amplifier that has 8 ohm outputs. For more information on this aspect, see the link below.
There is really no amplifier with an output of 4 ohms. All loudspeaker amplifiers have an output impedance of 0.5 ohm or less. Scroll down to related links and look at "Voltage Bridging".
Sorry, there is no 4 ohm amplifier in the world. All loudspeaker amps have an output impedance of less than 0.5 Ohm.

Will 8 ohm sub woofers work with a 4 ohm amp?
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!!!
Can a 4 ohm bridged car amp handle a 2 ohm speaker with proper amp cooling?
nope
What size amp do i need for two 10 inch kicker comp's?
You could go with a 600 watt 2 ch amp or a 300 watt mono block amp, depends on what OHM the subs are, if they are 8 ohm you could wire them down to 4 ohm or if they 4 ohm u could wire them to 2 ohm, i have a 600.1 Boss amp and subs are wired together at 2 ohm and they BANG.
What ohms am i running if i have two 4 ohm speakers hooked up to my amp vs two 2 ohm speakers?
Don't know how you have subs wired but should be 4 ohm load is what your amp will see.
Can you replace a 8 ohm woofer with a 4 ohm woofer?
Of course! As long as your amp's minimum impedance is 4 ohms or lower.
What will happen if a hook up an 8 ohm sub to a 4 ohm amp?
The sound quality won't be very good
Can you wire two 4 ohm subs to one 4 ohm amp the amp is only rated for 4 to 8 ohm load?
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".
Are kicker L7s good speakers and what kind of amp do I need to power 2-15 inch subs?
Yes, the L-7s are great. For the amp, you first need to find out whether the sub woofers are 2-ohm, 4-ohm, or 8-ohm. Depending on the answer to that question will determine whether or not you'll need a mono amp or a dual channel amp as well as the wattage.
Can you make 4 ohm output amp switch to 8 ohm?
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".
Can you hook up two 8 ohm svc subwoofers to a one channel amp?
If you connect two 8 ohm speakers to the average car amp, then yes, probably. Most car amps can handle a 4 ohm load, which is what it would be.
Can a 8 ohm amp power a 4 ohm speaker?
You will find no 4 ohm amplifier! So you will need no transformer. All audio amplifiers have output impedances of lower than 0.5 ohms. We have "impedance bridging" between amplifier and loudspeaker - no matching. Scroll down to related links and look at "impedance bridging - Wikipedia".
Wire 2 dvc 4ohm subs to 2 channel Amp-sub400rms4ohm amp 350x24 ohm rms 700x22 ohm rms 1400x1 4 ohm peak power Best way to set up?
This question makes little sense. Could you say what model amp it is? With two 4 ohm subs, you can either do 1 ohm or 4 ohm. Now if you have a bridgeable two channel, I think you can do a 2 ohm load. For a 4 ohm load, two 4 ohm subs, connect both positives from one side of the subs to the positive out. Then the negative coils from the opposite side (other side of the sub) to the negative output. Then connect the remaining negative and positive together on each subs. Look here http://www.the12volt.com/caraudio/woofer_configurations.asp
