Rockford Fosgate Advice in general?

I have a 1995 Ford Explorer Eddie Bauer Edition. I have in the back 2 brand goddam new Rockford fosgate Punch 12 in woofers, and an older 800 watt Pioneer Amp. I would like to know what everyone thinks of this system, it is not for competitions, i just like to have a louder stereo. It is wired into a factory JBL radio headunit in my truck, with an audiopipe Hi-Lo converter. I would also like to know of any type of amp that would make my subs sound better. Lastly, what songs would sound good (deep b) on my system. I am open to all types of music, gansta rap to heavy metal. Thanks for the help you guys.
