2 DVC 2 ohm wired to 4 ohm amp? Possible?

[ScreamingSkulls]

Hello everyone and please excuse the ignorance as this may sound like a stupid question. I have searched and search to find out if it's possible to do the following. My brother has a crossfire VR401 that I gave him and I really need it back as I have a Memphis Shallow 12. Anyways he has the following speakers:

2 Diamond CM310D2 (DVC 2ohm)

Amp I have that I was going to give him:

Sony 2 channel 800w Model: XM-ZR1252

Sony - Xplod 800W Class AB Bridgeable 2-Channel Amplifier - XM-ZR1252

Continuous Watts per Channel (4 Ohms) 125 x 2

Continuous Watts per Channel (2 Ohms) 170 x 2

Continuous Watts Bridged 340

Max Power Watts per Channel (4 Ohms) 280 x 2

Max Power Watts per Channel (2 Ohms) 400

Max Power Watts per Channel (4 Ohms Bridged)

Right now his subs are getting a 2 ohm stable wired to the Crossfire VR401 which is providing him 400W x 1 RMS at 2 ohm. I don't want to screw him over so I'm trying to see if the sony amp would provide a close RMS/Watts as the crossfire is.

Thanks for all your help.

Thanks and I know about that site and rockfords diagrams but I'm unable to find any info on 2ohm to 4ohm so I guess it would be safe to assume it can't be done.

Based off the amp details I gave you above the best wiring I can do for my little brother is to wire it up to the amp in 2 ohm load which would give me Continuous Watts per Channel (2 Ohms) 170 x 2 (170 per sub)? Is this the best possible solution you can see?

Thanks again.
