that kicker amp is underrated, i had one that rated 930.1 watts RMS at 2 ohms since it is not 1 ohm stable, loved the amp. i noticed the signal to noise ratio is a little higher on the kenwood. the kicker can handle more power with 2 40 amp fuses rather than kenwoods 2 30 amp fuses. the kenwood can go down to 5 hz and the kicker goes to 20 (which, below 20hz is inaudible but it can still be felt)

so i say the numbers are on kenwoods side, it may not be THAT much of an upgrade if one at all
