need help choosing amp!

i found out that for christmas, my parents got me 2 12" Rockford Fosgate Punchs and a Rockford Fosgate Amp(it was a package deal at bestbuy.) the only problem is the amp is only about 275 watts. im going to use that little amp for my 6x9's i have on the rear deck, but what size amp should i get for the 12's? I dont want anything to big/expensive, but i want to use the subs to their potential.

p.s. ill post pics of my car soon!

can you be more spacific on when kind of subs are they, are they Z, HE, HE2, HX2 model? which one?

yah if they are punch Z you should use that amp they bought, becasue they dont take a lot of power.
And also note that fosgate amps are UNderrated. Which means they put out more power than they say.
I used to have a Punch500a2, it said 500watts, but it was actually 640 when I bridged it
