No Problem to do this, but there are really no amplifiers with an output impedance of 4 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".

What voltage is applied to a 4 ohm resistor if the current is 1.5 amps?
Ohm's law: Volts = amps times ohms In the case of a 4 ohm resistor with 1.5 amps of current, the voltage is 6 volts.
How do you wire 4 dual 4 ohm coils subs to one ohm mono?
If you wire all 4 coils parallel, you get 1 ohm (mono).
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
Will two 4ohm subs running series and one 8ohm sub running parallel work together maintain a 4 6 or 8 ohm load if not how will the subs work together with a single monoblock amp?
4 Ohm subs wired in series gives an impedance of 8 Ohms. 2 4 Ohm subs wired in series, wired with an 8 Ohm sub in parallel gives you a final impedance of 4 Ohms. Speakers wired in series raise impedance, speakers wired in parallel lower impedance.
Dual 4 ohm subwoofer what kind of amp should you use?
4 + 4 wired in paralell + to + and - to - will give you 2 ohms. do this on both subs and then wire them together + to + and - to - and that will give you 1 ohm. so now get an amp that is 1 ohm stable 95% of mono block amps are. add your subs rms wattages together not peak let say your subs are 1200 peak and 600 rms then 600 + 600 equals 1200 watts rms is what you need. so for this instance i would need a 1200 - 1500 watt rms mono block 1 ohm stable amplifier. I like more power just in case after the subs get broke in they want more power.
Why buy an 8 ohm sub?
I have recently purchased 2 10" Kicker Comp 8-ohm subs for the simple reason that I already had an amp that matched the power rating for the subs at a 4-ohm load (amps rating). The amp will put out about 800w @ 2-ohm and 400w @ 4-ohm load (rms values). By running 2 single voice coil 8-ohm subs wired in parallel you are effectively cutting the impedance in half (8 + 8 = 4-ohm in parallel). To do this you simply connect the positive terminal of one sub to the positive of the other sub and then to the positive of the speaker output on the amp. Same with the negatives, sub to sub then to amp. Had I purchased the more common 4-ohm single voice coil subs my load to the amp would have been 2-ohms and too much power would be getting to the subs (100 watts more rms power than the peak power the subs could handle). I did this because of the space I had available and also because the Kicker Comp has performed well for me in the past as an entry-level woofer. Hope this helps!
How big should the amp be to two 12 subwoofers?
What you need to know is the RMS power rating and ohms of the subwoofer. (Example; RMS is 300 watts and it is a 2 ohm sub. This is what you would need. You have 2 subs so a total of 600 watts. So you want an amp with a max power rating of 600 watts, but he is the tricky part. They were 2 ohm subs. So your amp needs to be 2 ohm stable. No there all not 90% of amps are only 4 ohm stable.)
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.
How do you hook two subs up to one amp?
It depends on the impedance of the subs, whether they are single- or double-voicecoil (SVC or DVC), and the rated output impedance of the amp. If you've got two 8-ohm SVC subs and your amp is rated for a 4-ohm load, then you can put them in parallel. If you've got two 4-ohm SVC subs and your amp is only rated for a 4-ohm load, then you'll have to put them in series, even though you won't be able to extract maximum power from the amp. With DVC subs, you've got more flexibility to get an efficient match. In any case, you have to pay attention to polarity.
If 2 dual 4 ohm subs were wired in series parallel what would it put out?
The final impedance would be 4 ohms.
If 2 4 ohm subs were wired in series 2 equal an 8 ohm setup n you wire that in Parallel with another 4 ohm would it put out a 2.6 ohm load?
Yes, just make sure your amp can run at 2 ohms and you're fine.
