I have used skar woofers for many years now. I have done builds with the VD, VVX, DDX, EVL, VXF, and ZVX. I have never had a problem with the subs. I think they are a very budget friendly company as a whole. What this boils down to is your overall budget and power abilities such as electrical and amp power. The Rp2000.1 is a solid amp and will power any of the subs up to the ZVX rather well. Keeping your voltage up is key so you don't clip the hell out of the woofer and reach mechanical failure.
