I have a Sony Xplod 800 watt amp. Can i bridge this amp to power 2 Rockford Fosgate P2's 12inch?

i bought a car that came with 2 Sony Xplod 10inch Subs & an 800watt Sony Xplod Amp. I own 2 Rockford Fosgate 12inch P2's in a band pass box. I would WAY rather use my P2's instead of the Sonys. Can i bridge that Amp to the 12inch RF P2's??? I tried just switching them out but obviously the amp doesnt power them. Eventually i will end up buying a high wattage Amp for the P2's and then put the Xplods on the sides and hook them back up to the Xplod 800watt amp. what can i do in the meantime to power my 12inch P2's???
