Do you think two sets of components (rear w/tweeters mounted ear level/front w/tweeter mounted ?) would give me good imaging, or is this too much? Also, anyone have any suggestions on size/brand?

 

JK -
Install components in the front, for sure, but use regular 5x7 or 6x8 speakers in the back... as that is all you will need.
IMHO I would think that putting components in the rear is a little overkill and additional $$$ to spend too.
I have the Lightning's single cab and I am running my system with a set of components in the front because the RR are disconnected.
With 75Wx2 from a Sony amp I have ample power and plenty of juice to drive my Polk MM465.
Are my Polk comps worth their $300 price? Absolutely!!!
Would I put another $300 in the RR? Doubtful.

Good luck,

It about like a car in there w/room. I got the Crew Cab, there is a lot of room from the back to front. Thats why I was thinking components in the back w/the tweeters mounted ear level to help fill...
