Here's an example using three DVC subs.
Let's say you buy three DVC subs. Each VC on the subs are 3ohms.
You'll then wire the two VCs on each sub in series producing a total load of 6ohms for each sub.
Next, you'll wire the subs in parallel to the amp in parallel for a total ohm load of:
1/R = 1/6 + 1/6 + 1/6
R = 2ohms
Finally, find an amp that is stable into a 2ohm mono load. You'll probably want a very powerful mono sub amp.
