Well here goes. I have a 2 ohm speaker for the front and another 4 ohm speaker for the front as well, if i hook them up in parallel to the same channel what is the total ohms of the two speakers total???
Q#2...
I now have 2 speakers same set up, but both are 4 ohm speaker and they are connected in parallel, now is the total 2 ohms??
Also its hooked up to an amp one channel that has a 2 ohm at 140 wrms, or 4 ohms at 70wrms. If it is 2 ohm load from the 2 speakers does that mean that each speaker is getting 140 wrms or is it split in 1/2 and each speaker only sees 70 wrms???

why is one speaker 2ohm & another 4ohm?
you should have the identical speaker on the left & right

I have a 6.5 in the door, and a 4" in the dash and the other side same, i'm just wondering what will the ohm add up for the 2 on each side, meaning 2 ohm 6.5 and 4 ohm 4"..
You see...and just wondering if that will be a problem in hooking up to the amp power that i discribed earlier..

Yes it will be a problem.  Didn't we advise you before to can the 4" in the dash?  Regardless, placing a 4-ohm and a 2-ohm load on the same amplifier channel will do two things: 1) your net impedence on the amp will be 1.333 ohms, which may overload it, and 2) the relative loudness will not balance with the 2-ohm driver utilizing twice the amplifier power of the 4-ohm driver (and thus being louder.)

You need to do some homework.  I recomend going to this web site and commence reading, and keep re-reading until you start to understand.  You'll thank me for it later.
