How much money do you want to spend? And what kind of vehicle do you have?

Which version of the HX2's? RF makes Punch and Power HX2 series. Also which ohm model do you have?

I would honestly suggest sealed enclosures, but if it's a choice between free-air and ported then I'd say ported. You loose too much SPL much with free-air setups.

With four RFD2212's (4ohm Punch HX2's 500RMS 1000Peak) you need 2000RMS minimum. My best suggestion is to use 2 class D amps rated at apx 1000 x 1 @ 1ohm and wire 2 subs per amp. I'd suggest two JBL BP1200.1 amps. That amp is 1ohm stable and rated at 1200 x 1 @ 1ohm. Two of them would have more than enough power to properly drive your subs (each sub needs 500 RMS and would be receiving apx 600RMS from the amps, which is still within the limits of the sub). Here's how you would wire the subs (I'm only posting 1 diagram, but each of the 2 amps should be wired like this)...

I hope you've either already upgraded or have plans to upgrade your alternator and battery because 2400 watts is gonna put a heavy load on your electrical system!
