LakeRat, I say wire it up and see what it sounds like. That is all you can do. While I tend to side more with Diesel on this one (more of a quality person than a quantity person), getting good quality amps is worth each and every penny. You get what you pay for and normally even more. But, you have the amp, so, no sense in spending more money if it will do what you are after.
Wiht that being said, what I would tell you to do is to set things to where you would think they should be (ie, gain to 5V if your RCAs are running at 5V, etc). Then, crank the stereo and see how the balance is and what the sound quality is like. From there, adjust the gains to maximize your sound while keeping the quality in acceptable ranges. With this being said, the more distortion you keep in the system, the more likely you are to destroy speakers (distortion is what kills speakers, power takes a lot above the rating for quality speakers).
I am getting ready to install a similar amp (Kicker KV 700.5) into my Jag with a setup very close to what you have planned. Keep the individual subs at 4 ohm, but wire them up in parallel and then bridge the amp. That will maximize your output. But, please keep in mind that you are also causing the electronics to run hotter and therefore can lead to shorter lifespans. But, that is the price of running power.
