Newbie audio question - what is the advantage, if any, of going with a dual voice coil vs single for a pair of 12" subs? Does it sound any different when played at moderate levels?
Also, will my Punch 500 have enough power for (2) 12s?
BTW - this is going in my GMC Yukon.

if everything else is the same, you wont hear a difference at any level

all depends on what you want and what you have. if you want 'testicle smashing oontz' and have a pair of 12w7's, then no. if you want just some low end extension then maybe... it all depends on the sub(s)
what subs are you looking at? and why do you want two 12's?
When designing your system, you need to look at what your end goal is, and go backwards from there. Do you want it loud? Do you want it to play deep? Big or small box? From there, you figure out what equipment does what you want.
The biggest thing about DVC subs vs. SVC subs is the ability to change the way you pull power from the amp.
In your example, two SVC subs can be wired two ways: Series or parallel. In the case of two 4-ohm subs, that means you can have an 8 ohm load, or a 2 ohm load at your amplifier.
If you do this same configuration with two DVC subs, now you have more options. Let's say you have two DVC subs with 4 ohm coils. You can now wire it in various series/parallel combinations. In series, you have 16 ohms. Series/parallel you get 4 ohms. Parallel/Parallel is 1 ohm.
So where this comes into play is when you start working with different amplifiers. Some are not stable at low impedances, while others can handle low impedance loads.
For example: Some amps can be bridged, but the lowest impedance when bridged may only be 4 ohms. Two SVC subs would need to be wired as 8 ohms in this case, negating the reason for bridging the amplifier... but two DVC subs would be okay in a series/parallel configuration at 4 ohms total.
Another example: Let's say your amp is rated down to 1 ohm. Two SVC 4 ohm subs will only drop to 2 ohms, whereas 2 DVC 4 ohm subs can drop to 1 ohm, allowing you to pull more power from the amp.
This doesn't mean that DVC subs are better than SVC subs. If you match the sub and amp properly, it's simply a matter of deciding what works for your application and going from there.
Does this make sense to you, or do you need other clarification?

you can have 8 and 2 ohm configs with two 4 ohm dvc subs but with half the power handling.

Got the schematic? I'm trying to think of how to make it work and I'm baffled. I could see a 10 ohm load being done easily enough, as well as a 5.3 ohm load... But the other two, not so much.
Holy Crap - I thought I didn't know much about this stuff, and now I really know I don't know much. I have always had aftermarket equipment in my daily drivers and have been happy with the sound. I used deck power to power the 4 speakers and an amp to power my subs. I always had a friend hook up the speaker wire configuaration for my sub/subs. I used the low level inputs from the deck and power wire to battery, etc. for my amp installs.
I don't think (1)12" sub will give me enough bass in my Yukon. I had one friend tell me to go dvc and another tell me to go single because I would be wasting money with my listening style going with dvc. He looked at my Punch 500 and said I would be fine going with single voice coils - just hook up one side of the (-) and go to the other terminal and hook up the (+). Put two speaker wires on top of each other for each terminal and go to the subs. I'm thinking this will "bridge" it, but am not sure. I had one solobaric 12" and did not like the way it sound. I had (2) 12s in the past in other vehicles and was happy.
what subs are you looking at getting and what is your listening style? Also what is your goal with the subs. do you want something that just blends in seamlessly, something that stops your chest or a combination of the two?

I am looking at Punch Series 1 or Stillwater Kickers - svc. I do not listen to rap, hip-hop, or anything that has a lot of booming bass. I am looking for more of a hard hitting trap set bass drum sound - clean and tight for the bass drum, yet something that will make the bass guitar sound come through as well.

12" subs - single or dual voice coil?
