Anyway...

I am searching for 7 ch. of amplification (100x4, 200x2, 300x1) in two amps only ...
I am guessing you need this much power as follows...

100x4 (Mids & Highs???)
200x2 (Midbass???)
300x1 (subs???)

If so, you could make this easier on you by realizing that 50x4 for mids & highs is plenty of power to drive them into uncomfortable listening levels...

If I am guessing right... I recently bought 2 JL e6450 & I am very pleased with them... thought you might be able to work them into your design if their size allows it...

Here is a review on them...

The Alpines will fit...

Put the F345 next to each other (26" total length)
And the M605 is about 8" wide...

All 3 side by side is a total of 34"... looks to me the Alpine will fit with a little creativity...

I was recommending the 3 amp option assuming a 8ohm midbass...

For what it is worth, the F545 birthsheets I have seen have it cranking out 180+ watts per channel @ 14v... so it definitely has grunt ;)
