I have a kenwood  800 watts maximum peak power  and was wondering if it is better to buy the rockford fosgate 8gauge 500w amp kit or to go out and buy each individually?  or if there is something better out there?

I might as well add what type of subs i have so you guys can give me the best set up options...i have 2 12" Kenwood KFC-W3009<>wS('185','5') Single-Voice-Coil Subwoofers in a sealed box powered by the kenwood 800 w peak bridgeable 2 channel w/3 way power distribution (800 peak/460rms x 1 @ 4ohms, 460peak/230rms x 2 @ 2ohms or 300peak 150rms x 2@ 4 ohms)  how should I hook this up?

Any 8 ga. amp kit will work.  The load on the amp using these two 4 ohm SVC woofers will be 4 ohm stereo, or 8 ohm bridged.  You can get about 150 watts to each sub.

The subs should play okay with that.  They are rated at 200 watts RMS.  If you already have this equipment, then go with it like this.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

If i hook up my subs w/out bridging them, would that be better?  or will i get more if i bridge?

It will be the same.  4 ohm stereo = 8 ohm bridged.  When the subs are bridged, each channel reads a 4 ohm resistance load.  So hook it up however it best suits your installation.  You said both speakers shared a box, so use the bridged method.

Redstorm3,
The amp kit that you have is sufficient to do the job, but do check the minimum gauge requirement of your amp to be safe.   
“If i hook up my subs w/out bridging them, would that be better? Or will I get more if I bridge?”
Yes, you are better off not to bridge the connection to your sub. The amp will be much most sable not bridging.   Bridging the sub that you got will bring the impedance down to 2 ohm. Not a good idea since most amp is meant to be bridge at 4 ohm. If you want to get the most out of your amp. You can do this. Instead of running both of the sub, run a single sub at 4 ohm in bridge mode then you will fully maximize the power of your amp.   
Be careful whose advice you buy, but be patient with those who supply it.question on amp kits -- posted image.

Listen to Stevdart... 4+4=8, bridged to 8 ohms, your amp will see 4 ohms per channel... or run it stereo, with one woofer on each channel... It won't matter... same power, either way.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

I have a friend with 2 dvc 1ohm woofers. He want to wire them in a 2 ohm load stereo but he has a mono amp. Is that posible????
Dont use ten words when 5 will do fine.
