Help with single sub recommendations for 12" sub for a Rockforsgate Power 800.2 amp

I have had a Rockford Fosgate Power 800.2 sitting in my garage from my past car, finally going to put into another one of my cars but I no longer have the subs and very little trunk space because it's a convertible so I probably will get a shallow sub, I am looking at recommendations, single or dual voice coil, 2 or 4 ohms. I listen to a variety of music, some country, some R$B.

Thanks

Dennis
