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.

Correct way to hook up pioneer 12Ins sub woofer's champion series?
Depends if it is dual 4Ohm or dual 2Ohm and what Impedance your Amp supports. *If you amp can handle 1Ohm Load and you have a dual 2Ohm sub you can run the sub in parallel to get a 1Ohm load (parallel meaning both + are connected with each and same with both -) *If your amp can handle 2Ohm load and you have a dual 4Ohm sub you can run the sub in parallel to get a 2Ohm load. *If your amp supports a 4Ohm load and you have a dual 2Ohm sub you can run the sub in series to get a 4Ohm load. (series meaning the - from one coil is to be connected with the + on the other coil) Do not mix up Impedance's make sure you find out what your Subs Impedance is and what you Amps Impedance is
How do you wire dual voice coil 4ohm?

These are single voice coil. All JL Audio woofers are single voice coil except W6 and the 13w7. ?

What size of speakers are in a 1997 firebird?
6.5" 2 ohm in the doors, plus 1 inch 4ohm tweeter if you have monsoon 6.5" dual 4 ohm voice coil subwoofer in the sail panel. (highly recommend Elemental Designs) 4x6" round 4 ohm speaker + 1" tweeter if you have monsoon. There are no 2ohm voice speakers that I know of, so your sound output will be slightly lower with aftermarket speakers. If you dont have Monsoon, then you have 6.5" 4 ohm speakers, standard replacements apply.
How many channels do you need to power my subwoofer?
mono or two channel are the best for subs but it depends on if your sub is dual voice coil or single voice coil, what ohm load the amp can handle, and if it is single voice coil and are using one sub you need to make sure you can bridge a 2-channel amp if that's the kind you chose... Next question you ask it may help to add a bit more detail. If I knew the sub brand and model, ohms, and if it's dual or single voice coil i could help answer that much better.
Can you replace a dual voice coil speaker with a single coil and how do you wire it?
If you are going to replace a dual with a single you need to look up bridging it would be some thing like "{Right +}{Left -}
How do you wire amp to 1 ohm load?
need more info but I'll give it a shot and hope i answer your question. You will need one of the following to get your desired ohm load: 1- single voice coil at 1 ohms 2 - single voice coil at 2 ohms wired + to +, - to - 2 - dual voice coil at 4 ohm all wired + to +, - to - so that you only have 2 wires conected to the amp. hope this helps.
What do you set your amp to for 2 12 subs?
to mono if your amp will allow, also this is for single voice coil. otherwise run in mono parallel to run dual voice coils.
What is a voice coil?
a voice coil is the electromagnet that causes a speaker horn to move in response to the electrical impulses received from the amplifier.
What does HSS stand for on stratacaster guitar?
It stands for Humbucker, Single-coil, Single-coil, in reference to the type of pickups used.
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.
