Eh, if the sony's are what ya got, then roll with them. Better subs exsist for sure, but thats all water under the bridge now that you've laid down some cash for them. I assume they are 4 ohms, maybe an old usacoustics 800f amp will do the trick? That should give you around 400 watts persub, I believe its rated power was into 2 ohms.Otherwise, pick up any new amp that'll do about 3-400 per side, some decent brands are mtx, xtant, orion and kicker...just make sure you think about the possibility of upgrading in the future, in other words, maybe find an amp that can make a lot of power, and run your current subs at an 8ohm load (less power to the subs the higher the impedance goes), that way, whenever you do get around to getting new subs, you have some other options, and can maybe keep a hold of the current amp you have.
