look at this thread : Elate 3 ways and power
damo95 has the smaller x100.4 amp and is using 3 way setup not focals though but high class speakers in the same caliber as the focals
maybe shoot him a pm or email, this will at least give you an idea of the product, the x200.4 looks like a moster very powerful too
looks like the pg amp has the power you need i think carsound did a test on the new pg range but not the amp you are looking at, check out the web site
