Good amps, but I'd actually want a little more power for those subs. They will work though. With the lower tuning, you will lose a little output, so I'd actually want a little more power than what the PCi comes with... Are you buying these new? What exactly are you trying to achieve and how big is your room? You'll also need to feed them with an already crossed over signal as those amps have no x-over. For a sub, I like to see an amp intended for use with a sub to be honest. Yes, plate amps have the drawback of not being self contained though.
