Hi. I have a set of 6.5'' infinity reference speakers each at 60 rms, and a set of 4" infinity reference speakers each at 35 rms. Both sets are 2ohm. I ordered this>> (http://www.crutchfield.com/p_113KAC6404/Kenwood-KAC-6404.html?tp=115&tab=features_and_specs) kenwood amp to power them. It runs 60 rms to every speaker at 2ohm, which is perfect. Right? Also, I have two 10", 4ohm, infinity Kappa perfect subs each at 400 rms. I am thinking about ordering this kenwood amp>> ( http://www.crutchfield.com/p_113KAC9105/Kenwood-KAC-9105D.html?tp=115&tab=features_and_specs) and run them in parallel. I'm thinking that would give them each 450 watts power, which is more than enough. I do realize that I would have to be careful not to blow any of my speakers, but I will probably never have them turned up loud enough to blow them anyway. My questions are,, did I choose amps that will compliment and bring out the full potential of my speakers? and also, will my alternator be able to run both of these amps at the same? I do not know anything about my alternator. But its new, I had to replace it less than a year ago. I have a 98 Toyota 4runner... if that helps any...
I'm kinda new when it comes to this car audio stuff, so let me know if any of my reasoning is wrong. I plan to wire everything myself, so if anyone has any tips of any kind that would be great.
Sorry for the long ass question.. but thanks in advance for any advice!!

(also, I'm ordering from amazon, not crutchfield, for crutchfield is significantly more expensive. I just posted the urls from there because crutchfield had all the information about the amps in an organized manner)
