Newbie needs help with speaker placement !!

[snowmanx]

Bought some speakers because they sounded awesome to me but now I can't decide where to put them...one of those issues that one guy says this way is better and another guy says that way is better. Looking for more opinions.
System is going in a 2005 Dodge ram Quad cab
Head unit is a Pioneer AVIC n3, with JL audio XR 653 3-way component, 6.5", 4" and tweet. Will be powered by JL slash 300/2 amp.

Obviously I've spent a little bit of dough and would like it to sound great...so where is the best place going to be for these speakers???

Response from another audio forum, that didn't seem to helpful.

"why would you put all speakers in the door? Also, how are they going to separate the back wave of the 4" from the backwave of the 6 1/2"?--every system I have heard them in were active setups. Not passive. These are not hack install/tunes either. "

Well...where should they all go then??? I was going to put the 6.5 in the stock door position, and the 4-tweet up in the dash, but like I said, two different installers said for sound staging they should all go in the same plane???? One installer said that it would sound stupid any other way and looked at me like I was retarded for even thinking of putting them on different planes, or even in the dash.

Other ways are like I already stated, or get some kick panels ang put the 4"-tweet in that, with the 6.5 in the stock door position.

I honestly don't know what is best and am trying to trust the "professionals"

Any more input would be great!

Thanks
