2 or 4 Ohm amp/8 Ohm Sub

when you have 8 ohms, there is more resistance than there would be if there was only 4. your sub will not be getting as much power as it was if it was only 2 or 4 ohms. if it is dual voice coil, you can hook it up to be 4 ohms and that is the way that i would do it.

  I have a 660 rms power acoustik fahrenheit amp and a 600W rms15" volfenhag sub in a 5.25 cu. ft. wedge box."In this bright future you cant forget your past"

with a dvc subwoofer think of it as two 4 ohm subs just hook it up like you were hooking up 2 4 ohm subwoofers

yeah, just put the positive and negatives of each coil in the same spot on the amp

what's the model number of the amp? The reason I asked is if it is a mono amp then you could wire the sub to 2ohms safely like this. But if it is a 2+ channel amp then we'll need to figure out something else because most 2+ channel amps are only 2ohm stable Stereo and 4ohm stable Mono. Hard thing to do with a single 4ohm DVC (unless you want to risk independant wiring).Squirrel

Your amp is listed as being 2ohm Stereo stable, but not 2ohm Mono stable. Which means you can either wire each voice coil independently to its own channel at a 4ohm load on each channel giving apx 330RMS to each coil (which is not recommended though, read more here on the dangers of independent wiring), or you can wire the sub into a bridged 8ohm load which will give you apx 400RMS to the entire sub. IMO, With your current equipment you would be better off (and safer) wiring to the bridged 8ohm load for 400watts. You would be underpowering the sub, but you wouldn't run the risk of it tearing it apart by using different input signals. Here's how you would wire it to an 8ohm load... Squirrel
