Don't get Pyle, they're low in quality chart.
If the CV's are really 600w rms, then you need 1200w rms amp to power both. Since you mentioned 4ohms DVC subs, that means the amp has to put out 1200w rms @ 4ohms or 1ohm. Therefore, look for am that has those numbers. |

So i got the CVs. they say they are 600w rms each (1200w rms pair) and can be wired at 1 or 4 ohm. Will this amp work before this buy it?
Memphis 16-PRD500.1 500x1 1OHM RMS
RMS Power (W) 200X1 @ 4ohms / 300x1 @ 2ohms / 500x1 @ 1ohm
THD @ 4 ohms 0.05%
Frequency Response +/- 0.5dB 10Hz - 500Hz |

if they are 600 rms each and you get that amp, you will only be fully powering one of the subs with 500x1 at 1 ohm, look at teh memphis 1000d or whatever the name of it is if your lookin at memphis specifiacally |
