Amplifier Subs

Do I have the wrong amplifier for my subs?

2 12 inch DVC 4 ohm Rockford Fosgate Punch P3D412 Subs each 500 watts rms, and a 1200 watt 2-channel MA Audio amp model number HK-898. Doesn't seem like my subs are hitting as hard as they should, so I'm wondering whats going on.

How do you have them wired up? Like this?

That should give you a 2ohm load....
And the amp here:
Specifications: *Power output: 300 watts RMS x 2 (4 ohm load), 500 watts RMS x 2 (2 ohm load), 1200 watts RMS x 1 (bridged mono, 4 ohm load)

So if you wire them as suggested by Crutchfield and assuming your amp should hit it's mark on power/watts rms....500x2 and 2ohm...then the amp SHOULD be fine for those subs.
Personally not a BIG fan of those subs and that amp. But again your subs and amp should be fine. Make sure you are not sending a crappy clipped signal to your subs...(you think they aren't hitting hard...) you turn up the gain, gee still not...you turn up bass boost, still not...crank the volume...ugh...then you start sending square waves to your subs...causing it to heat up and burn up the coils. Even if you TURN EVERYTHING UP on an amp that does not produce more power or less power than you need you can cause the subs to clip and therefore burning them up...
