First off are the subs dvc 2 ohms or 4 ohms? because kicker amps do not like to be wired to one ohm. once you determine how many ohms you have then i can recommend an amp for you...
if your subs are dvc 2 ohm you can wire the subs down to two ohms like this picture

however if your Subs are dvc 4 ohm the safest setup for the kicker amp would be to wire them to 4 ohms like this picture

and as for the amp id prolly step up to the 1000.1 jus turn the gain down a little... NEVER max out the gain or risk having to buy a new amp or subs 75% is pushing it
