okay I got a question for you guys with experience. I have the option of puting 5.25 components or 6.5 components up front in my car. I have 6x9s in the rear. Now I will have subs with some decent power going to them so what size do you think I should put up front for my speakers. I know this is kind of a vague question but in your experience what size would sound better when the speakers would be used exclusively for highs only. Also the speakers will be amped if that helps any. Also here is what will be included in my setup. I have heard all independently and liked them but I have yet to hear them together.

Pioneer deh-p9400mp head unit
kenwood excelon dual mag components up front(not sure on size)
kenwood 6x9 4 ways in rear(I know a little much but I got a good deal on them so what they hell....)
kenwood excelon kac-x501f 4 channel amp for speakers( at the most 100 watts per speaker at 2 ohms)
2 12in dei viper subs in sealed box
1200 watt viper mono amp powering the subs
all monster cable wires and cables for hookups.

What do you guys think?? I am not going for any competitions obviously, I just like my music loud. Do you think I made the right decisions for a decent setup?? thanks in advance!!!!
