Hi, I currently have a Infinity kappa one amplifier wired at 4ohms to 2 DVC Kicker 07cvr124 (old) subs.
The amp specs are
Number of Channels/Type Mono / subwoofer
4-Ohm Power Output 500W x 1 less than 1% THD + N
2-Ohm Power Output 800W x 4 less than 1% THD + N
Bridged Power Output N/A
Total Peak Power Output 1600 Watt
Class D Operation Yes, with DirectFET transistors
Signal-to-noise Ratio (IHF-A) 112dBA (ref: rated power, 4 ohms)
Frequency Response 20Hz–320Hz (-3dB)
THD + N less than 0.05% at rated power (4 ohms)
Input Sensitivity 200mV–6V
Some sites list the amp as 1ohm stable with no RMS rating and i'm worried ill blow the subs or the amp if i wire them down to 1ohm. I would rather wire the subs to 2ohm but the 4ohm DVC subs can only be wired to 4ohm or 1ohm.
My other choice is to buy 2ohm DVC subs and wire them to 2 ohm on this amp.

According to the crutchfield site, the minimum impedance is 2 ohms.
If it's not designed for 1 ohm, it will either go into protect mode or fail. If it fails, it could damage the subwoofer.

says 1ohm stable. Are crutchfields listings more accurate?

That appears to be an original Infinity/Harmon document but it's also 4 years old so they may have changed the rating (or the crutchfield information may be wrong). Contact tech support at Harmon to see what they consider the minimum safe load to be.
the weird thing is I actually emailed them and got no response, so I called them and the tech support guy said "I'm not sure myself".
