Ok maybe I am making a mistake thinking I'm going to be able to run a good active crossover system on my first system ever. I'll start out with what I do know, if I get a good enough head unit I can run active straight off of it, I don't need anything better than that for now. Also I know that I have room for 6.5" speakers in the doors and 1" tweets in the A pillars. But what is the difference between a 2 way and 3 way speaker? Also I have pretty much no way to go listen to quality speakers unless I want to drive about 3 hours to the only decent car audio store around. So I know you are all going to say that I need to hear them myself to decide but that is just out of the question, I'm hoping that I can get the sound I want just by going active. I can describe that I enjoy a mellow tweeter but not too mellow, also in a speaker im not a SQ phile but I don't want any distortion and I want a little midbass presence. I know I can't get much midbass unless I get speakers just for midbass, but that won't be needed. Also they can not be drowned out by the 18" BTL in the trunk. Also what kind of headunit would be sufficient to run active on and have everything I'm going to need? I need a AUX plug in the back and I would like it to be easy to read and navigate through the menu's. I plan on powering these with the Sundown 100.4, but will this be too much power on the tweets if so will I need a seperate amp just to keep from overpowering the tweets or how does that work. I am completely new to this if you can't tell and I am looking for a little help. Thanks.

pioneer 880 Would do the trick nicely. And let you run your active fronts.

I am seriously considering this 880 it looks like a great head unit, but I read that a problem they have is you have to manually ground the rca outputs? why is this?

Poor design. It's an issue with most of the Pioneers. BTW, the Sundown amp actually should have enough crossover capability for you. It, of course, doesn't have time alignment or EQ ability. The Alpine 9887 will do what you need, too, and it's cheaper. As far as power balance goes, you can simply dial down the gains on the tweets if they are too overbearing.
