Lets say I got one of those new kicker subs, hooked up a 5000watt rms amp and a 800 watt 4 channel amp. The current draw is going to be close to 500amps. What would i have to do to have my truck handle that? The alt puts out 90amps max. I can put one extra alt and upgrade the current, but I'm still looking at a 300 amp overload - What can I do?

Are just going to use this setup for competition or for daily use?

In that case do the extra alternator but make sure to get a really big heavy duty one, also get the factory alternator rewound as high as it can be done.  I would also add a couple of batteries in the back, I would recommend at least two marine deep cycle batteries with an isolator.  I would also put in a 12 volt power supply to charge the batteries if you use more than two.  Also I am not familiar with the sub/s, but 5000 watts in anything other than a competition vehicle is over kill.  I am content with my two HX2 12 hitting 148.

I'd be happy with 2 more RF HE 3412's and another 500bd

Kicker says that it need's 5000 rms  but I think that if your not gonna use it for comp's but instead everyday listening, then I would believe that maybe 2500 to 3000 rms would give a good sounding result. What do you think?

But at $1600, I think I'll just stick to my 15 L5's instead, that way I know I don't need 5000rms to move those....LOL
