Car Audio Online Shopping

What type of configuration as give me the cleanest low, but with too much power?
I shop online for car radio and I'm stuck I do not know the submarines I want and I'm looking for ideas I do not want to overload the lowest point, but I want something to really blow CfaN if they can work both ideas in a context for the sub and amp? and what kind of box? Thank you!
My system is a 1800W Kenwood monoblock and two 12 "Kenwood 1200W subs and I highly suggest this combination for both price and quality. a picture, I did mine, but I heard things really well on boxes of Polk Audio.
