Since they are 4 ohm svc's then wire them in parallel and get yourself a mono amp.  It'll put your impedance at 2 ohms and be an almost perfect match for a lot of mono amps that run best at 2 ohms.  You shouldn't have a problem with overheating and depending on the amp, (and enclosure) you should have some pretty nice bump!

Alright, Kenwood just came out with a 600 watt amp that is mono and itll run stable at 2 Ohms. Im pretty sure Im gonna go with it. Its only about 150, and itll run 250 cont. into each speaker. I'm building my boxes today and I might get the amp too. Thanks for the help guys!

I have one sub,SVC. The memphis amp is a class D mono!!!I plan on running 4 SVC subs on it @ 1 OHM!!!

If it says 2OHM stable then It isnt real class D. It is mosfet technology. A real class D amp wont get hot @ low OHMs, And can run 1 OHM no problem. With a mono mosfet amp you are limited due to the OHM load!!

Not all class D amplifiers are stable into a 1 ohm load.

What? It is obvious from praddling like that, you have no idea what you are talking about. NOTHING that you just said makes any sense, and what did make a LITTLE sense wasn't even true!
1: There are "real" Class D amplifiers that are only rated to run 8 ohm loads. The impedance into which an amplifier is specified to run safely is Z-E-R-O indication of the class with which it is designed. It is an indication of the capabilities of the power supply, and/or the current capabilites of the output devices themselves, but it CANNOT in any way, shape, or form, tell you the class in which they are running.
2: MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is the type of device used in either the outputs or power supply drivers. It is a transistor type. There are still plenty of amplifiers made that use standard NPN and PNP transistors, and don't even come near the MOSFET technology.
3: ANY class of amplifier is limited by the impedance. It is STILL based on the capabilities of the POWER SUPPLY, and is no indication of the class of the output stages, whether Class A (the least efficient of audio amplifier classes) or Class D (the most efficient).
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

You are dangerous, you think you know more than you do and are giving BAD advice. haemphyst is right you cant tell a class bt the Ohm load.

http://www.ikesound.com/kenwood_kac_x10d i would consider this amp. i would also consider a amp that is 1200rms and stable @1 ohm to add 2 more svc 4 ohm subs.

If you don't mind orange you can pick some good gear from quantum audio.
