I am thinking of buying this will it work well? (Sub and Amp)?

It seems like a waste to pay for a Kenwood amp and then run it to a Pyle subwoofer. If you do some searching you can probably find a better amp for around the same price range but keep in mind that amps do not necessarily mean volume. Running a 3200 watt subwoofer (I'm guessing that a peak rating, which you shouldn't use in the first place) with a might actually produce less sound than running it to a 1000 watt subwoofer. If the subwoofer's RMS rating (which I couldn't find listed anywhere) is around 1000 watts then it should work fine.
