which amp for older tower speakers?

Opinions please:

I want to get a new amp for the set of Boss 530's on my tower. Trying to decide between a rockford fosgate 5002 or a Kicker zx450. I have no experience with either, and the speakers are currently running off of the clarion 401.2

I think i read somewhere that these are wired in a 2 ohm configuration but not sure. I have a $200 budget and these seem to fit the bill. Any suggestions?
