I don't see any problem running them from different amps, in fact, some serious competitor run each side with single amp ie: 2 amps for front stage only, but no rear speaker, as it will render useless in SQ competition. The goods will be more dynamic and better separation, the bad will be running a new cable and assesing the vehicle electrical system if it can take one more amp.

Just use 2 amps....one to power up your front stage and the 2nd one to power your subs. Just run the rear fills off the headunit, but to answer your question...
Good: you'll be surrounded by music (if don't really care about staging)
Bad: more $ spent for the amp and rear fills, more space taken up by the 3rd amp, your staging will be crap

"88 300CE- First Year Production
Here my explanation on why I even thought of this. Stock my 300ce only has 2 speakers in the front and two in the rear. The two in the front are new but just 4" focals and the rear I'm installing 5 1/4" MB Quart Components. Then I have these two 2-channel amps sitting here and the one I was apposed for the fronts is just a phase linear 120w amp with rms of 18x2 @ 4ohm, which I hardly find that to strain the battery at all. For the rears I have a 2-channel eclipse ea2212 with rms rating from 50w-70wx2, which should complement the components well. Currently my car has that old tweaked style factory fader in it and speakers need to be rewired. For the front amp I was just gonna mount it deep in the passenger footwell and the rear one yes in the trunk intercepting power from the 4 gauge power wire already back there from the subwoofer amp, run a small rca off the subwoofer amp as well as it has an auxillary output jack. I already have all the wiring I need (8 gauge) to do this. For the front I'll run the wire from the battery and the rear I use a "T" distributor block. My car is a e-class coupe so speaker staging should be too crazy as I installed the rear tweeters almost parrallel to where my headrest are (I sit back kinda far). By the way my subwoofer is just one 10" eclipse sub powered by a pheonix gold 800watt mono amp. In my past I've had some older eclipse non-preamp decks that I fell in love with, and this new alpine I got has the feature to act as if it's non amplified and I want to take advantage of this again. So whats your thoughts now?

I find that keeping the system as simple as possible works better, ie splits up front run by single 2 channel and the sub run by a monoblock. Unless you bring passenger all the time, i don't see the need for rear speaker. Sell the extra gear and buy a better one

I would ditch the Phase Linear amp since you said it puts out a mere 18 watts per channel. Personally, I think it would render useless running that amp since your Alpine head unit would probably put out the same kind of power if you ran the speakers off of it. Most Alpine units would run a minimum of 16 watts rms per channel. I highly suggest powering your Focal’s with your EA2212, set your gain & crossover accordingly, then run your MB Quarts off your head unit for rearfill. About your tweeter location, I would change the location to the front…somewhere near the A-pillar or near the side mirrors. Just think of it this way….when you’re at a concert….where does the music come from? From the front, right? Plus, with your tweeters mounted so close to your ears….doesn’t that give you ringing in the ears after awhile? Anyhow, that’s my .02 cents. My system in my beater is similar to yours. Alpine 9831, MB 4” components off a JL 300/2, Eclipse SW7104DVC.T2 off a PG Tantrum 500.1. This is how I mounted my tweeters

well my components aren't installed yet, but I do love sound quality and right now without the rear speakers my ride is lacking midsrange, Are 4" speakers really capable of pleasing me?

I'm in the same boat....4" in my dash lacks any midbass. 
My only other option is to go for some 5.25" or 6" on my door panels, but I'm really discouraged about drilling a big hole. I like to keep the interior close to stock as possible for that inconspicuous look.

true at concerts music does come from the front, but hearing music in a studio or in surround like a movie theater is always better/clearer than live.

Hearing a movie and music is two different things. In a movie it is a neccesity to have 5.1 setup. In music as w211 Ryda said, staging up front is more important. Technically, in SQ competition, your system is judged by how well it reproduced stage condition, ie where is the singer in the stage, where is the piano in relation to the singer, etc. But it'll come down how ur ear is like to be pleased

Makahveli,
I forgot to mention these to you if you're in dire need of midbass from a 4" speaker. Too bad they're not in 4 ohm configuration.

Hey Makahveli,
I have a 124 Cabrio with a similar type set up. I have a set of 4" mids in the dash, tweeter in the door mounted just ahead of the seat controls and a 6 1/2" mid bass drive in the stock location in the lower part of the door. There is a 4 channel amp driving just this. A pair of channel for the 4" and tweeter and a pair for the 6 1/2". As for having the old style doors, you might be able to find a set of new style at a wrecking yard or ebay and swap them out.
There is another amp driving a pair of 6" coaxils in the rear location.
And since I have a cabrio I have another amp driving a 10" sub in the passenger side footwell.
Sounds great, it's really nice and clean.
Joe

is a speaker pod made for this car? Check with Q-logic and see... as far as what your asking...
1 using a whole jib jab of seperate components isnt going to help you. What everyone IS missing is that SOME components are actually made to be driven by seperate amps... The MBquart Q series, and the 3 way Boston Accoustic components as well are designed to be driven by 2 amps. They give power to the tweet and seperate power to the midbass.
Now to comment on your tweet mounting locations... BEST location for a tweeter is with in 6" of its mid base component.
