The Soundstorm products are in about the same category as Boss, Visonik, Pyle, and Lanzar to name a few. Somewhere between overrated and definitely overpriced for the quality you get.
Look into the Alpine MRP-M1000. RMS = 1kW into 2ohms (600 into 4ohms), YES 4 OHMS(!), real power. No, it WON'T do one ohm. But most of those claiming to are not CEA2006 compliant anyway and can claim any power at any load and advertise for whatever buyers they can attract for their bottom-of-the-barrel products.
The MRP-M1000 is currently on sale at Crutchfield for only $347. Awesome power, and very good sound quality, too. I'm currently running 2 4ohm MTX Thunders off of "little brother", the MRP-M500, and they really shake the pavement.
You have to spend good money to get good power, there is no way around that.
The only wiring configurations for 2 2ohm DVC subs result in 0.5ohm, 2ohms, and 8ohms impedance. Check the Rockford-Fosgate "wiring wizard"
for the different diagrams.
Hope this helps.
