I would highly recommend putting a decent set of splits in the front and amp them as well though. 2 12inch subs will definitely over power the factory speakers especially if you just run them off the H/U. It would sound terrible, but you might be into lots of bass and not much else. If so then go for it! I would also suggest removing/disconnecting the centre speaker as it is so small and weak it detracts from the sound quality.
I've drawn a rough diagram (not much of a drawer) for you to refer to for the wiring as described above.
