Just saying it powers 400 WRMS @ 2 Ohms doesnt tell if that rating is in mono or stereo. If its in stereo 2 Ohms then obviously you know what wiring you have which makes me ask why post this?
Exactly.
Also, to the original poster, you mentioned in the first post that the first diagram was of the subs wired in PARALLEL. Actually, only part of this is true. Each sub is wired in SERIES, if you look, each sub has positive to negative, then the leads left over wire the TWO subs in PARALLEL with each other. So what happens is, each 4 ohm DVC sub is wired in SERIES to 8 ohms, then they are wired together in PARALLEL to bring them back down to 4
ohms.
If you wired each sub in PARALLEL, each would produce 2 ohms resistance, and then if you proceeded to wire them together in PARALLEL, the resistance would drop to 1 ohm. However, if you wired them to 2 ohms each and then wired them in SERIES, it would bring the resistance back up to 4 ohms.
This is why DVC's/QVC's make for such flexibility in resistance wiring. The diagrams on Fosgate's page, and Infinity's page, and JL's page are all great, but if you want to really understand how resistance works with subwoofers and how impedance affects amplifiers, check this out:

I agree with the other posters here that wiring the subs together and bridging the amp to mono would most likely work better than giving each its own channel, especially if both subs are sharing the same enclosure/airspace with no separator.
