From your quick response, I take it you did not read the entire thread.
You are not robbing efficiency from the speaker by running one voice coil.
Facts are not opinions. And science is not based on opinions.
Yes, this is an internet forum, however, we have many professional members here. If you take the time to read through the threads in the two links I posted, you should be able to recognize who is qualified and who is not.

With one single 4 ohm and two dual 4 ohm voice coils wired to an amplifier channel, whether in parallel, series, or a combination of both, you will always have one woofer getting twice as much power as the other. Attempting to connect all of them to a mono amplifier, one pair will always receive twice as much power as the other, hence my suggestion to use only one voice coil on each DVC woofer with the SVC woofers. If you have two amplifiers or two channels with separate gain controls, run the SVC woofers on one and the DVC woofers on the other if you want to use all voice coils on the four woofers you have now.

You know what's silly? Arguing with a car audio professional on a car audio forum especially where the professional OWNS the forum. :)

"...There are 2 reasons we use dvcs In car audio one is for expanded wiring options but the second that comes into play is powerhandeling capabilitys. When you wire a sub in parallel you are changing the gauge of wire it's the same as running 2 runs of power cable to amps it allows for more current to flow each wire is carrying half the current effectively changing gauge".
Can anyone explain how this is even remotely possible?

It's not possible. c0ryp1 has been misinformed and/or simply does not understand what a dual voice coil is.
~wirewise~ Verify all wiring with your meter before making any connections!

This is the thread I've been searching for. I have as kicker in its own ported box and its 4ohm dvc and I have 2 svc 4 ohm subs in a qbomb ported box. My pioneer gm d9701 mono block had the rms to push all 3. This is my first build and I'm overwhelmed by the videos and can't grasp how I wire them.
