Alright, from what I understand, you have the type-r DVC which are 4 ohms each, meaning that you can either run them at 2 or 8 ohms. To get the most power out of your amp, then this is what you are going to have to do.
Wire the subs (the voice coil) in parrallel (positive to positive, negative to negative)
This will give you a sub which is now 2 ohms. Once this is done, just wire them up to your amp as if you were running it in stereo. The JBL BP1200.1 is a mono amp, so it will automatically run those wires in parrallel which now give you a 1 ohm load. That amp is 1 ohm stable, but you won't get an increase of power from going from 2 ohms to 1 ohm.
Those subs can handle 300 watts a piece with no problem, and they peak out at about 1000 watts, so you will be pushing more than enough power, so make sure that you adjust the gain right so that you don't over exert the subs.
If you want, you can also wire them up to a 4 ohms load to just get 600 watts. Reply if you want to know how to do that.
