Just one of those cheap truck boxes. Similar to this except it has a port hole as well:

Since you have a ported box, it's tuned for a certain frequency, which you may or may not know. Each speaker is going to be built differently and require different size ported boxes for the tuning you are looking for. The 50 watt more power will not give a noticable difference, most likely. The RF sub is prob set up better with the box, with its tuned frequency being more of what you hear or like.
If you want, try sealing the port in the box to make the box a sealed, it will totally change the sound, more quality, which may sound better or more of what you want. just a suggestion

Goto the kickerwebsite and see what they recommend box wise (ie. how much air space it takes)

Actually...better yet call kicker and tell them what type of vehicle you have, the music you listen to, and the amp you have. Then they can tell you exactly what size box to build....they have specs for almost every vehicle. The specs on their website are just a guideline.

Quick STUPID question.. Am I sending TOO much power to this sub? Am I sending 500W RMS?? This is what the doc says:

Maximum Power Rating
All Channels - 1000 W
Continuous Power Rating (RMS) - Measured at 14.4 Battery Volts
4Ω Load Per Channel - 62.5 Watts x 4
2Ω Load Per Channel - 125 Watts x 4
4Ω Load Bridged - 250 Watts x 2

And I have it hooked up like so:
