Hi, i got a pretty good deal on a RF p6001bd (600w rms @2ohm) and now i dont know what sub to get. I was planning on getting a Kappa 12.1 perfect (one sub is plenty for me, plus im broke) but i dunno if the amp is too powerful for it since its rated at 350w rms. This is going to be my first system so i dont really want to blow anything. I've looked at some audiobahn and rockford subs but there are so many i dont even know where to start. Any suggestions?

thanks in advance,
Phillip
