oem rear speakers 2 or 4 ohm ?

[revstohigh]

I have done a lot of searching and correct me if i am wrong but word is that the sun and tune amp under pass seat is a 4 ch 200w 4ohm amp ?

but the front speakers are 2ohm . does this mean the front tweeters are also 2ohm ? and combined they = a 4ohm load ?
are the rear speakers 2 or 4 ohm ? i think they are 4 but not sure. im aware that they are a full range one way just need ohms.

I have a set of 6.5 polk momo components with crossovers from back in my thumping days . Since front has such shallow depth I would like to use woofers of these in the rear . and put the tweeters up front all running of rear amp signal (im aware this will require me to run aditional wires to the front doors) . Then i want to put a cheap , brand name pair of 2ways up front , no longer sharing its signal with the stock tweeter .
I will also add a small powered sub prolly the kenwood 5x7 150w which will run of a line converter .

if my calculations are correct this should put me at an even 4 ohm load on all speakers ?

I am happy with the oem Head unit for now and deff want to take advantage of having a stock amp till i outgrow it....

any corrections to my ohms or suggestions will be apreciated

Sounds like more of a "technical" question
someone should chime in with an answer.
I don't have the factory amp, so I'm not sure

new rears installed oem was infact 2ohm front and rear so i assume the amp is 2 ohm aswell . not very happy with the new rears ..... they are much clearer but very quiet compaired to the fronts. i had to fade half to rear to get a good ballance will either be replacing them all with aftermarket 2ohm 6.5's or putting 4ohm front components up front and replacing the hu and amp ......
