Stereo??

I am doing my stereo and have some questions right now and am wondering if anybody is running what i have and how they are powering it? So I have 4 fosgate punch 6.5" 60 watt rms I don't have a amp yet for those so need advice but my thing is I am probably going to upgrade those to Polk um's in the next year so I'm trying to get a amp I can use for both setups. Secondly I am probably going to get a w3 10" jl sub at 400-750rms and which amp will be a good fit? And is anyone running this I have room for a 1.75 cu. sealed box. Also I have a amp but not sure if I can run my fosgates off it. It is a kicker zx450.2 2 channel and rms is 250 watts to 2 channels can I split that which would be almost perfect but the fosgates are 4 ohm so I'm not sure if it makes a difference( Iam not a stereo guy at all lol) ?and lastly I am thinking of splurging on rev 10's but never heard them while riding so is what I want to know is can you hear the music crystal clear or is muffled? And what amp is a good fit? Now I know I'm getting good equipment but at the same time I wanna use my money smartly so bang for the buck as far as amps go. Thanks in advance!
