There are many different ways that you could wire two dual voice coil subwoofers.
Depending on how you connect the voice coils, you could have 1ohm (all coils in parallel), 4ohms (parallel-series combination). Technically you could wire them for 16ohms (all in series), but this isn't done in practice because an amplifier won't provide much power to a 16ohm load.
You should wire the subwoofers to make an impedance (which is the 'ohms') which will match your amplifier. Not all amplifiers can handle 1ohm, so you may need to wire the subwoofers for 4ohms.
Be sure to do some research on this before wiring anything up or you could damage your amplifier. For some helpful wiring diagrams, check out the Fosgate Wiring Wizard:

What do the subwoofers ohms for?
the ohm is a unit of measurement based off of someones last name. When used in subwoofers, for example 4 ohms or 8 ohms, it actually determines the amount of watts the speaker needs. Like if two identical subwoofers were taken and one was 4 ohms and one 8 ohms and applied say 150 watts to each of them, the 4 ohm would be louder because ohms are the speakers resistance and the lower the ohms the less amount of power it takes for the subwoofer to reach a specific loudness. That's why professional huge subwoofers may be one ohm, because an amplifier that has less power than the sub could still power it because since its one ohm, the 500 watt amplifier at 4 ohms could be 1500 watts at 1 ohm.
Can you run two eight inch subwoofers requiring 50-100 watts of power each running at 4 ohms with a 2 channel 4 ohm amp putting out 75 watts per channel without damaging the subwoofers or the amp?
Yes
Yes this amplifier works with a variety of subwoofers with various ohm loads. The amplifier will product the same power at 1.5 - 4 ohms making this a great choice for most subwoofers. ?

What does the term dual voice coil mean in regards to car audio speakers?
AnswerDual Voice Coil in regards to subwoofers means there is 2 positives and 2 negatives. Its just used to wire up different ohm levels. Like if u have a subwoofer that are dual voice coil @ 4 ohms then u can parallel or series wire it to become Single Voice Coil @ 2 ohms. Google the word Series Wiring or Parallel Wiring for examplesAlso this type of speaker is one of the few that can be connected to 2 different amplifiers at the same time and still work properly. One coil is connected to the car stereo and the other coil is connecter to my scanner.
You have an Alpine type X 1243D subwoofer you are trying to decide if running it at a 2ohm load at max power or a 4ohm load at two thirds of its power range will work better?
Multiple subs wired together must be the same coil type and impedance. If they’re not, the power won’t divide evenly between them, and some subs would probably be over-powered while others get under-powered. If you want to run different types of subs in a system, each type needs to have its own separate amp. Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating. Figure out the possible total impedance(s) that the subs can be wired together to form. (SVC = single voice coil, 1 pair of terminals; DVC = dual voice coil, 2 pairs of terminals.) 1 SVC 2-ohms can only have 2 ohms of impedance 1 SVC 4-ohms can only have 4 ohms of impedance 1 DVC 2-ohms can have 1 ohm or 4 ohms of impedance 1 DVC 4-ohms can have 2 ohms or 8 ohms of impedance 2 SVC 2-ohms can have 1 ohm or 4 ohms of impedance 2 SVC 4-ohms can have 2 ohms or 8 ohms of impedance 2 DVC 2-ohms can have 2 ohms or 8 ohms of impedance 2 DVC 4-ohms can have 1 ohm or 4 ohms of impedance 3 SVC 2-ohms can have 6 ohms of impedance 3 SVC 4-ohms can have 1.3 ohms of impedance 3 DVC 2-ohms can have 1.3 ohms or 3 ohms of impedance 3 DVC 4-ohms can have 2.7 ohms or 6 ohms of impedance 4 SVC 2-ohms can have 2 ohms or 8 ohms of impedance 4 SVC 4-ohms can have 1 ohm or 4 ohms of impedance 4 DVC 2-ohms can have 1 ohm or 4 ohms of impedance 4 DVC 4-ohms can have 2 ohms or 8 ohms of impedance Look for an amplifier that can put out power up to the RMS wattage at an impedance load the subs can be wired to form. 8 ohms — figure on the amp putting out half the power it would at 4 ohms 6 ohms — figure on the amp putting out three-quarters of the power it would at 4 ohms 3 ohms — figure on the amp putting out the average of what it would at 2 ohms and at 4 ohms 2.7 ohms — figure the same as for 3 ohms, and add a few watts 1.3 ohms — use the 1-ohm spec and take away a few watts Example: You have two Alpine S Series S-W8D4 8" subwoofers and you want the right amp for them. They are DVC 4-ohm subs rated at 300 watts RMS each. Two 300 watts RMS subs together need a maximum total of 600 watts RMS. Using the chart in Step 2, 2 DVC 4-ohm subs can be wired together to form a 1-ohm, a 4-ohm, or a 16-ohm load. The last is too high a load to be practical, so you’ll look for an amp that can put out up to 600 watts RMS into either a 4-ohm load, or a 1-ohm impedance load: up to 600 watts RMS x 1 at 4 ohms, or up to 600 watts RMS x 1 at 1 ohm Among Crutchfield’s selection of amplifiers you’ll find: Memphis Audio PRXA600.1 — 600 watts RMS x 1 at 1 ohm JL Audio JD1000/1 — 600 watts RMS x 1 at 4 ohms Kicker KEY500.1 — 500 watts RMS x 1 at 1 ohm Any one of these high-quality amplifiers would work well with those subs. It doesn’t matter which impedance an amp plays through — 600 watts RMS through a 4-ohm load produces the same volume as 600 watts RMS through a 1-ohm load. You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms. Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms. Two subs on a 500 watts RMS amp will want about 250 watts RMS each. So you’ll look for subs each rated for 250 watts RMS or more. Using the chart in Step 3, for two subwoofers, a final 2-ohm load can be achieved with either two SVC 4-ohm subs or two DVC 2-ohm subs. So, you’ll look for two subs that are either SVC 4-ohms or DVC 2-ohms, rated for at least 250 watts RMS each: 2 SVC 4-ohms, at least 250 watts RMS, or 2 DVC 2-ohms, at least 250 watts RMS Among Crutchfield’s selection of subwoofers you’ll find: You have a Memphis Audio SRX500D.1 amplifier and you want it to drive two subwoofers The amp is capable of 350 watts RMS x 1 at 4 ohms and 500 watts RMS x 1 at 2 ohms. Let’s say you choose to maximize the amp’s potential and want the system to put out 500 watts RMS. This means your subs have to be wired to form a total impedance of 2 ohms.

How do you measure speaker impedance?
The real impedance is the resistance in ohms more 20%. A coil resistance of 6,7 ohms X 1.20 = an impedance of 8.04 ohms. If the voice-coil had exactly 8 ohms, the impedance would be 9.6 ohms and the sound would be unclear, tending to more basses.
What causes subwoofers to blow up?
the reasons a subwoofer blows is the amount of power running through the speaker is greater than the speakers RMS, or peak power. the cause for this could be the amplifiers power is set higher than what the speaker could handle, because certain amplifiers run too much wattage for speakers with only 2 ohms, for instance. You can also blow subwoofers having set your volume too high, then turning the stereo system off completely. when you turn it back on, it causes the voice coils to spring harshly, blowing the inside. you know a speaker is blown when you play music through it, it sounds like a bag of coins rattling when it performs.
If the current running through a wire is 1.2 amperes and it passed through a resistor of 7.5 Ohms what is the voltage of the system?
9V by using ohms law
Can you run a single 2ohm dual voice coil sub and a single 4ohm DVC sub off a single mono amp?
It depends on the amplifier. If you absolutely want to leave the current subwoofer configuration as 2ohm and 4ohm, the resultant impedance seen by the amplifier is as follows: Both wired In-Series: 2ohm + 4ohm = 6 ohms Both wired In-Parallel: 1 / ( (1/2) + (1/4) ) = 1.3 ohms The Parallel configuration can probably be only run by a 1ohm-stable amplifier whereas the 6ohm Series configuration can be run by any amplifier that is able to drive anything under 6 ohms. Also if ran in the Parallel configuration, this mismatch in driver impedance may also cause the 2ohm subwoofer to receive more power, resulting in a different sound characteristics than the 4ohm subwoofer. Usually with DVC subwoofers you want to match the impedance between drivers. If possible, configure each subwoofer to 4ohms and connect them in Parallel. This will produce a total impedance of 2 ohms (you need a 2ohm-stable amplifier). If your DVC subwoofers only support 2ohms and 8ohms do either: Both wired In-Series - configure subwoofers to 2ohms: 2ohms + 2ohms = 4ohms Both wired In-Parallel - configure subwoofers to 8ohms: 1 / ( (1/8) + (1+8) ) = 4ohms.
What amp would be best for two 12 jbl w12gti mkii?
For two 12" JBL W12GTI MKII subwoofers, a monoblock amplifier with an RMS power output that matches or slightly exceeds the subs' RMS power handling would be ideal. Look for an amp that delivers clean and stable power at the impedance (ohms) your subs are wired to – usually 1 ohm or 2 ohms. Make sure to consider the size of your vehicle's electrical system as well.
