There are a lot of possibilities here, especially since your question is worded exactly right.
I'm taking it you have 4 12" speakers, each of which have Dual Voice Coils (2 Ohms each). You want to wire them together and see what ohm load you have.
Ok, there's multiple ways to wire this up. Series, Parallel, and Series/Parallel combo.
Wiring these speakers in series can give you either a 4 ohm load, or a 16 ohm load. 4 ohms if each speaker by itself (having DVC) is wired in parallel and 16 ohms if each speaker by itself is wired in series.
Wiring these speakers in parallel can give you either a .25 ohm load, or a 1 ohm load. Again .25 ohms if each speaker by itself (having DVC) is wired in parallel and 1 ohms if each speaker by itself is wired in series.
Wiring these in a series/parallel configuration can give you tons of different wiring options and ohm loads. In your case .75, 1, 3.2, 4 ohm loads.
So your best option would to be wire your speakers up in series, with each speaker wired in parallel to itself. This way you'll get a 4 ohm load, if done properly. Make sure your amp can run a 4 ohm load too.
Because it has a Dual Voice Coil (DVC) which gives you more wiring options, eg. dual 2 ohm coils that let you wire in parallel for 1 ohm final, or in series for 4 ohm final load. You MUST use both of them for proper operation of you risk damaging the sub.
I = E/R = 12/1,000 = 0.012 ampere = 12 milliamperes.
P=VI=V^2/R P=12x12/6=24W
If you connect three 4 ohm speakers in parallel, the amplifier would see a load of about 1.3 ohms. This definitely could damage the amp if you drive it too loud.
In a 12VDC circuit with a 1K load, there will be 12ma of current. (Ohm's law: Volts = Amps * Ohms, so Amps = Volts / Ohms.)
You don't play a PC game with a dual shock 3 PS3 controller
If your home receiver is not rated for a 2-ohm load (many can handle a 4-ohm, but not a 2-ohm), you will damage components inside the amplifier by over-current. Don't use car stereo components in home stereo equipment. It's like using a hockey helmet to ride a motorcycle.
unfortionatly it alot more difficult than that. you first need to know if your subs are dual or single voice coil. then the ohm of the coils. your next step is to make SURE your amp is one ohm stable. (most are not) if your sub ohm will match you amp ohm. safely. its all in the wireing of the amp to the subs to change the ohms. if you dont know exactly how to wire them DONT DO IT yourself.

16 ohm, R1 + R2+R3 = RT in series.
The 12V battery connected to the 2.4 Ohm combination will supply 12/2.4 or 5A. The individual currents will be 12/3 or 4A for the 3 Ohm resistor, and 12/12 or 1A for the 12 Ohm resistor. The 2.4 Ohm parallel combination is obtained from a simple product-over-the-sum calculation.
The ohm is the unit of electrical resistance to current flow. More ohms (more resistance), the less current will flow. Less ohms (less resistance), the more current will flow. One ohm is defined as the amount of resistance that will cause one ampere of current to flow if the supply voltage is one volt. Ohm's law states that amps = volts / ohms So, if you had a 12 volt battery, and you connected a load, say a heating element that had a resistance of 3 ohms, how much current would flow in the circuit? amps = 12 volts / 3 ohms amps = 4
