Which of these Subwoofer + Amplifier packages would hit the hardest in a SUV?

mtx might sound a little more clear on hip hop songs but if your going for extra hard bass and have people hearing you come down the road and almost pushing your back glass out the kenwoods my kenwoods hit extremely hard I only have a p300.1 amp pushing both of mine. You can't hardly breathe in my card they hit so hard.
